Figure 1 below illustrates the development of how the topic was researched step by step across time. While the earlier book (Brautigam,2009 ) shows the general map of how China take actions in terms of finance in Africa, which is theoretic and lack of data support, the later article(Brautigam and Gallagher,2014 ) collects the officious data from 2003 to 2011 and focuses on the particular commodity-backed finance which is more specific in explaining the finance pattern: the Chinese government usually allows borrowers to repay these RMB loans with export goods, such as Tanzanias exported cashews, which are used to pay for†¦show more content†¦Instead, Brautigam and Gallagher (2014)point out that it is of speculative concern and both articles emphasize the inner importance, public opinions and data-based analysis about commodity-backed finance (Brautigam and Galla gher ; Brautigam and Hwang,2016). They both regard commodity-backed finance as the vital driving force in maintaining the finance pattern of Africa. Despite the similarities above, there are some difference among the researches. Method is the most obvious one .To work out the Chinese finance system in Africa, Brautigam(2009)interviews some related government officers and businessman to access to the financial pattern without specific data support. In contrast, Brautigam and Gallagher (2014) set on previous work by Brautigam (2009) and examine government, bank and press reports in both China and borrowing countries ,from 2003-2011, to copy-edit a list of loans and their characteristics. Then to copy-edit these data, he uses a scientific review of online media (Lexis/Nexis and Factiva) and then complicate these reports through consulting a various accessible sources in different languages.

Risks and Responsibilities of Coaching Free Essays

string(33) " under the control of the coach\." The purpose of this paper is to look at the area of risk management with reference to the sport of swimming. There is no doubt that the ability to prevent any types of injury to athletes is of the utmost importance. The safety of the athletes should therefore be the primary concern of both facility managers and coaches. We will write a custom essay sample on Risks and Responsibilities of Coaching or any similar topic only for you Order Now By working together, one would hope, that all unnecessary injuries could be prevented. One of the most severe injuries that can occur is that of a spinal injury. The area of prevention that addresses this issue is that of spinal injury management and it will be looked at more closely later in this paper. Even with all the extra emphasis in this day and age on safety issues, these kinds of injuries are still far too prevalent. In 1996, Michael Berger and Judith Middleton state that in the United Kingdom, there are around 40,000 children each year that suffer from head injuries. Some of these individuals will have received severe injuries, in that they will have been unconscious for at least 20 minutes and so will most likely have suffered brain damage. The sport of swimming has the obvious danger of drowning. There are also potential risks of spinal injuries caused by collisions with the floor of the pool, the walls in the pool and other swimmers. Many other injuries can be the result of a slippery deck or training equipment not correctly stored away. There is also a risk of injury from the chemicals which are present at a pool such as chlorine. Aquatic injury prevention should be part of any facilities risk management program. Risk management involves identifying and reducing dangerous conditions that can cause injuries and financial loss. Thus, the aim of a risk management is in a way a kind of preventative medicine, to tackle the issue of a problem thus ensuring that those kinds of accidents will not occur. There are some that would contend that those individuals that suffer an injury are unfortunate victims of circumstance. Many injuries can be avoided through an understanding of the factors that can cause injuries to occur and then a knowledge of how to go about preventing such situations to occur. Charles Bucher and March Krotee (1998) explain that there is an added risk in any physical education exercise as opposed to a regular class because the children are moving around and not sitting in a chair. The hiring of competent, qualified and certified employees in crucial not only for the planning but also for the conducting and supervising of activities. By making these simple efforts, the risk of injury can be minimized. Not only should the staff be up to par but also any equipment used as well as the facility being as safe as it could be. All coaches need to have fully up to date certificates and licenses. All necessary measures need to be taken to prevent any injuries from occurring and the correct level of supervision is crucial. Bucher and Krotee explain that the coach is required to act promptly in performing first aid and CPR and nothing more. Coaches should always show all necessary levels of care in their professional activities. The American Red Cross (1995) suggest that by understanding how injuries are caused, this will help prevent them from occurring by increasing the staff†s awareness of risks and hazards, helping patrons to avoid risky behavior and developing an attitude of safety at your facility. The Institute of Swimming Teachers and Coaches (April 1997) explain that by identifying not only what is a potential hazard but also assessing their risk level, and then evaluating whether or not all necessary precautions have been taken, this should help to prevent anyone getting injured. The ISTC, were not only referring to swimmers as potential victims but also to coaches, teachers, lifeguards, cleaning staff and receptionists. According to Bucher and Krotee, there is no doubt in today†s society that there are ever more increasing cases of teachers, coaches, schools and teams being sued in court. It seems as though lawyers are readily available, also the public are becoming much more aware of their rights, as far as what they should be protected from a safety standpoint. It is suggested that the risk of legal action can be minimized by following some simple steps. Collecting all pertinent facts about the health of your athletes. Purchasing only the best equipment form the most reputable dealers and acquiring used equipment from companies renowned for high quality reconditioned merchandise. Not laying the blame of an injury on anyone verbally but by carefully wording the exact nature of the injury and the preceding events on an accident report. Good supervision and instruction in very important. An emergency action plan should be drawn up, rehearsed and be ready to be activated at a moment†s notice. All necessary insurance precaution should be taken. Perhaps this is the most comforting defense for a coach. According to the United States Swimming, Inc. 1998 Insurance Summary, all swimmers registered with United States Swimming are covered by the USS Insurance policy as long as the injury suffered by the member was received during an approved activity under the policy. All USS swimmers are covered when they are participating in competitions, meets or events sponsored or sanctioned by USS, participating in organized, scheduled practice sessions and in organized, supervised travel to and from sponsored and sanctioned events or organized, supervised practice sessions. Anthony McCaskey and Kenneth Biedzynski (1996) explain that coaches are those principally the defendants in law suits as it is generally agreed that coaches have the most control of those individuals in their respective sports. A coach may be found negligent if he does not follow his duty to conform to a standard conduct that protects others from unreasonable risk of harm. Participants are termed as either those directly or indirectly under the control of the coach. You read "Risks and Responsibilities of Coaching" in category "Essay examples" Case law demonstrates that coaches responsibilities include: supervision, training and instruction, safe usage of all equipment, provided high quality assistants, warning of potential dangers, providing prompt and correct medical care, preventing injuries to competing athletes. The American Red Cross (1993) explain that lawsuits are becoming a concern for those giving care. Hence in the case of an emergency, the lifeguards and coaches are becoming increasingly apprehensive about giving care to victims of injuries. The American Red Cross suggests that by being aware of some basic legal principles, individuals may lessen the chances that they may later be found to be negligent in some area or another. All lifeguards have a duty to care. That is, they are legally bound to provide care to a injured party if the giving of such care is laid out in their job description. The rescuer should follow a reasonable standard of care and failure to do so may result in a chance of being found negligent. The Good Samaritan Laws protect anyone giving care as long as they are not negligent and they act in good faith. Consent should always be obtained from the individual. If the victim is an adult and they refuse care, one must not force care upon them. In the case of a child, the consent must be obtained form a parent or guardian. Any victim that is either unconscious or confused is assumed to give implied consent as it is assumed that if that person were fully aware of their predicament, they would accept the care that was offered. To obtain consent, the rescuer must identify themselves to the victim, give their level of training, explain what could be wrong and explain what care is planned. Once care is begun, a rescuer cannot stop giving care until advanced medical professional arrive at the scene. Confidentiality must also be observed. Only the facility or team spokesperson may speak to attorneys or the media . A rescuer should only speak with law enforcement officers and the rescue squad when it arrives. Finally, record keeping is essential. The documentation is considered to be almost as important as the care itself. Bucher and Krotte (1998) state that coaches and instructors are expected to carry out their activities with all necessary levels of care. If this is not the case, then they are leaving themselves open to a potential lawsuit filed against them for negligence. There is a requirement for the coach or instructor to take protective measures. Failure to do so will result in a lawsuit. In Roth versus New York (1942), all necessary measures were taken and a bather drowned after walking into deep water. There was nothing to stop this happening. The state was found to be liable. Bucher and Krotee explain that the failure to supervise correctly is the most commonly litigated situation. By having alert lifeguards and coaches, a facility can seriously reduce to chances of injuries occurring. According to the American Red Cross (1995), effective surveillance has four elements. The ability to recognize the ways in which a drowning or distressed swimmer behave in the pool. An example of this would be that a swimmers would have rhythmic breathing, relatively coordinated movements, have a horizontal body position and be making recognizable forward progress in the water. In contrast a distressed swimmer would be breathing but also be calling for help, waving and be making very little forward progress in the water, if any at all. A passive drowning victim would be considerably different to a swimmer. A Passive drowning victim would not be breathing, have no arm or leg movement, could be face down near the surface or in a submerged position and so obviously would be making no forward motion in the pool. Appropriate scanning techniques should also be employed to locate swimmers having problems in the pool. Lifeguards should be carefully and strategically placed throughout the facility. Each lifeguard should be fully aware of their responsibilities. Coaches are responsible for teaching swimmers all necessary skills to compete, the correct procedures to reduce the risks of injury and making sure that their swimmers are physically fit enough to compete. The failure to provide adequate training or instruction to reduce the risk of injury has been a commonly cited reason in recent litigation. Supervision is absolutely critical when the consequences of depriving the body of oxygen are considered. Soon after breathing stops, then too will the heart. After six minutes or so, brain damage is possible. Between six and ten minutes without breathing, brain damage is likely. If breathing is stopped for more than ten minutes, usually the brain damage is irreversible. Thus it is very important to be aware of the varying depths of water within the pool. In this way it is much easier to make sure that the children do not wander into water which is too deep for them. Also, this could help prevent spinal injuries from occurring by making patrons aware of when and where in the pool it is considered safe to dive. Without doubt, patron surveillance is one of the most important parts of a risk management strategy. The Certified Pool Operator (Fall 1997) states that it is very important to regulate the use of pools, by watching children and though constant supervision of the pool. The Institute of Swimming Teachers and Coaches (April 1997) mentioned that in some pools there may be blind spots resulting from the positioning of features, glares and reflections. All of these factors can hinder surveillance and so through careful planning, these problems should be attempted to be eliminated by strategic placing of lifeguards. This comes directly under the realms of a good risk management program. According to the Certified Pool Operator (Fall 1997), it is critical to identify areas of the pool that become slippery when wet. These range from the deck itself to corridors leading to and from the pool, locker rooms and snack areas. Communication can be used as a tool for helping to prevent injury and so is considered another ‘gear in the engine† of risk management. Patrons need to be made aware of potentials for injury. They also need to be educated as to the risks from inappropriate behavior. All rules and regulations necessary for the prevention of injuries need to be forcibly enforced. Signs are needed to warn pool users of danger areas. Since spinal injuries are more common in individuals visiting facilities for the first time and so are unaware of shallow areas. The side of the pool itself needs to be mark both on the deck it self and on the side of the wall facing the water to warn swimmers in the pool as to the changing depth of the water that they are in. In addition to signs depicting â€Å"No Diving† and the depth of the water, facility rules and regulations should also be clearly displayed. Running should never take place around the pool. As the side of the pool gets wet, it become treacherous. Signs should be posted prohibiting to consumption of food and drinks in and around the pool. There is the obvious potential for injury from broken glass on the pool deck or in the pool from bottles that are accidental dropped on the pool side. Pool rules are not designed to prevent the patrons from having fun but more so to allow them to have fun in a hopefully relatively risk free environment. The pool rules should be displayed clearly on the wall of the pool. There are many great examples of pool rules, on would be that diving is only permitted in diving designated areas. The deck needs to be checked daily for loose floor materials. There is also a risk for standing water on the deck itself. All such findings should be immediately reported to the facility manager. The deck should be kept clear of equipment and anything else that could be a potential hazard. The American Red Cross (1992) recommends that in areas where the water is less than five feet deep, there should be signs clearly stating ‘Danger-Shallow Water- No Diving†. It is suggested that these signs are close to the edge of the pool in contrasting colors to the pool deck. If starting blocks are removable, they should be during recreational periods and should be stored in a safe location. If they are not easily removable, then they should be coned off or clearly marking as out of use to recreational swimmers. All kick boards and pull buoys should be stored away in their correct location and not left strewn about the pool deck. Any item left on the pool deck is a hazard. Any risk management program would include keeping the deck clear of obstructions. The American Red Cross (1988) states that all rescue and first aid equipment should inspected on a regular basis. This equipment should also be easily accessible. Any piece of equipment that is found to be damaged in any way should be removed, repaired or replaced immediately. Following an emergency, all equipment that is used should be replaced promptly. Other areas should also be checked on a regular basis, such as the showers, locker rooms and restrooms which should be kept clean and hazard free. Coaches are also responsible for taking all necessary measures to ensure that all equipment used by their swimmers is of an adequate standard. This issue is far more critical in a contact sport such as football where inadequate padding may lead to serious injury. Anyone working with chlorine should wear protective clothing such as gloves, goggles and clothing covering the rest of the body to minimize the risks of chlorine coming in contact with the naked flesh. Chlorine can enter the blood via absorption through the skin. Direct contact with the eyes can cause severe injuries. The American Red Cross (1995) terms chemical hazards as harmful or potentially harmful substances in and around the pool. Storage areas of chemicals should be clearly marked hence warning both staff and patrons of possible dangers. The doors to such storage areas should be kept locked. Any suspicious odors in these regions should be reported immediately. The American Red Cross (1992) recommend storing all chemicals and chemical testing kits in child proof containers and out of children†s reach. Every year many individuals are injured from diving related injuries. These injuries are usually caused by collisions with the bottom and sides of the pool. Thus it is of paramount importance that coaches and instructors take all precautions to prevent such injuries form occurring. Diving should not be taught unless all necessary safety equipment in readily available such as a back board and staff trained in spinal injury management are present. Coaches should make sure that all swimmers are educated in the obvious safety precautions. Never dive when someone else is in the water in front of you. All dives should be of a flat nature. All swimmers should enter the water fingers first and not head first, thus helping to cushioning the blow should the swimmer crash into the floor if the pool. Never hold or position objects in the pool. A great example as to why it important to keep the diving area clear of obstructions is given by the American Red Cross (1992), which referred to the case Bill Brooks. One day, he dived into a pool and hit his head on an inner tube. He could remember laying face down in the water and being unable to move. Brooks, who once played college baseball, is now a C5 quadriplegic and will never walk again. The best protection against possible injuries is an informed, safety-conscious swimmer. The Certified Pool Operator (Fall 1997) stated that in a typical year there are about 400 events that result in a quadriplegic injury in aquatic environments. According to the CPO, a quarter of these occurred in pools. The article went onto explain that 95% of the pool related injuries occurred in the shallow ends of pools. Through careful supervision and prudent coaching, swimmers can be educated as to safe methods of entry into shallow water. The Swimming Times (1997) suggests that the depth of the water should be taken into account in relation to the ability and height of the pupils. Hence, none swimmers should not be taught in water that is ten feet deep and likewise, competitive swimmers should not be coached in shallow water. McCaskey and Biedzynski (1996) swimming incident rates come be totally eliminated if swimmers did not use racing dives into shallow water during practice or meets. According to McCaskey and Biedzynski, there has not been a direct injury in college swimming since a non-fatal one in 1982. The American Red Cross (1995) reveals that sports related injuries account for 13% of all spinal injuries. These figures were derived from the National Spinal Cord Injuries Data Base. According to the American Red Cross, about 1000 people each year suffer spinal injuries from diving mishaps. The American Red Cross suggests the following ways to help prevent the occurrence of such injuries. The water depth should always be ascertained before entering. Only trained swimmers should be using the starting blocks. Coaches should be aware of these aspects and make sure they correctly supervise their swimmers during warm ups at competitions and at practice. All these measures mentioned so far in the paper appear to be obvious, but unless they are adhered to tightly then mishaps can occur. It is not worth gambling with your swimmers† health. If a suspected spinal injury occurs, then the area must be stabilized and immobilized. There are certain situations when a spinal injury must always be assumed to have occurred. It is always better to be safe than sorry. If proper precautions are not taken when caring for injured victims, then that lack of risk management leaves the coach and facility open to legal action. A spinal injury should be assumed for any injury involving a diving board, diving into shallow water, a fall from a height greater than that of the victim†s height. Also any visible bumps or depressions to the head, altered consciousness or complaints of back or neck pain from the victim. In some cases, the victim may be face down in the water. Although, the victim should be moved as little as possible following a suspected spinal injury, in this situation, the victim needs to be removed form the water. If the victim is not removed, drowning will take place, the heart will stop and soon there after, brain damage will occur. The American Red Cross First Aid Manual (1993) explains that head injuries can rupture blood vessels in the brain causing pressure to build up leading to brain damage. The American Red Cross (1992) describes the typical recipient of a diving injury as a first time visitor to a location, not warned by a sign about the potential dangers, when lifeguards were not present and the water depth was less than four feet deep. Any good risk management program could dramatically reduce the risk of this kind of injury. By having vigilant lifeguards, water depths clearly marked and no diving signs clearly posted on the deck, most of the risk can be reduced. These are all components of a well rounded risk management program. Since most spinal injuries occur when a person dives into water less than five feet deep, on arriving at a pool, a coach should check the poolside for all relevant safety warnings and make his swimmers aware of this risks. The facility staff should also be highly alert at all times. All pools should have an emergency action plan. The EAP should explain exactly what procedure should be followed in the event of an aquatic emergency. The initiation of the EAP is the responsibility of the lifeguard. A typical signal to all pool patrons and staff is three long blows of a whistle. This would draw the attentions of the other pool patrons and then they would be more easily removed from the water for the protection of the victim. Also, other staff members throughout the building would be alerted of the EAP being activated. The next stage is to begin whatever rescue or emergency action that needs to be taken. After determining the nature and extent of the emergency, another lifeguard or staff member will call the police, fire or rescue squad as necessary. The emergency number is usually 911 but may vary from area to area. If the pool a which you coach is in a new area, it is your responsibility to make sure that you are fully aware of the number to call in the event of an emergency. The required first aid should be continued be given to the victim until advanced medical care arrives. Once care is commenced, it cannot be withdrawn, if it is, this constitutes abandonment which is a liable situation. Once advanced medical care arrives, all necessary accident reports are filled and the aid in crowd control. More often than not, only one person is designated as the spokesperson for a facility. This person and this person only is allowed to talk to anyone except for the police and the rescue squad. The Institute of Swimming Teachers and Coaches (April 1997) explains that whether or not a pool operator believes that his pool is a high or low risk facility, it is essential to have an emergency action plan. According to the ISTC, an emergency is anything considered to of danger to a bather or employee. The following all come under that general description. Overcrowding is a situation where too many people are in a confined area. This could be fatal in a swimming pool. A good risk management program would outline maximum numbers for a pool. These levels would be set well below that of over crowding, hopefully eliminating this risk. Disorderly behavior is also a common cause of emergencies. With vigilant surveillance and firm enforcing of pool rules and regulations, this too could be eliminated as a risk. Lack of water clarity will occur when the chemical levels in pool be out of balance. This too is a liability. If a child dives into water which he assumes to be deep but is in fact shallow, this could lead to a lawsuit. Especially because of the fact that the water clarity may have directly affected that child†s judgement. The ISTC explains that as a coach, it is your responsibility to know how to raise the alarm, how to get help form other staff members, how to initiate the appropriate rescue, who should summon the emergency services and so on. Qualified lifeguards are trained to act as a team in the case of an emergency, thus it is crucial for a coach or instructor to be able to contribute positively to an emergency situation. The Institute of Swimming Teachers and Coaches (May 1997) states that teachers and coaches must be trained in what to do in the case of an emergency and in turn should make the pupils understand and be aware of the procedures involved in the EAP. The pupils needs to know where to congregate in case of an emergency and possibly if they will be required to stand near a particular doorway to attract the attention of the advanced medical care when it arrives. The Institute of Swimming Teachers and Coaches (1996) stated that 93% of the schools in a survey had a formal emergency action plan. Two schools stated that they did not have one. Most of the schools in this survey had had swimming as part of their curriculum for more than six years. Coaches and other facility staff should go through regular in service days to rehearse emergency procedures. The emergency action plan should be rehearsed most importantly. For this procedure is what could make the difference between life and death for a victim. In service training should cover the following points: review the potential hazards at the facility, review and update rules and regulations, practice the emergency action plan , practice rescue skills, carry out physical conditioning. Following an emergency, an accident report needs be filled out by the members of staff involved. The facility information such as address and phone number. Personal data of the injured party should also be included: name, age, sex, address. The location of the incident should be included as well as the a description of the incident. It is very important to include what care was provided; was medical attention welcomed by the victim or refused? All of these issues are very important as law suits are far too prevalent in this day and age. Remember, consent must be obtained from the victim. To obtain this, the care provider must identify himself to the victim, give his level of training, explain what he thinks is wrong and then explain what he plans to do. If the victim refuses care, the care provider must try to convince the victim to receive care. According to the American Red Cross (1993), record keeping is nearly as important as the actual care given. The record is a legal document and is vital if legal action is taken. Risk management is an important function of a sport program. A coach should be fully aware of all legal and ethical responsibilities that come with his position. Any form of negligence on his or her behalf resulting in increased risks of injury can lead to the increased chances of legal action. Risk management is not only concerned with limiting the chance of injuries being suffered but also reducing the chances of financial losses following such an incident. Coaches† Quarterly (1998) states that effective in 1998, all United States Swimming coaches must have the following qualifications: Safety Training for Swim Coaches, First Aid and CPR. The Certified Pool Operator (1997) blames the individuals for their careless behavior. According to the article, pools are becoming safer. The main reasons for injuries today are victim†s carelessness. In a perfect world no one would need to know rescue techniques. Everyone would be careful, and safety would not be a problem. But ours is not a perfect world. Because of dangerous situations, careless or carefree people, and changing water conditions, many dangers are in and around water. Risk management in a pool environment is basically concerned with aquatic injury prevention. A highly developed risk management program will substantially reduce the risks of injury. By understanding how injuries are caused, one can better prevent them. Effective communication with patrons is critical for helping to prevent injuries. Through this communication, the patrons can have fun in a safer environment. How to cite Risks and Responsibilities of Coaching, Essay examples

Answer: Introduction: The strategic financial analysis report has been prepared t investigate over the various techniques and tools which are useful for the company to make a better decision about the position and the performance of the company in concern of the competitors and the last year performance. Financial analysis is a study which is performed by the analysis, investors and the management of the company to analyze the stability position, profitability position, and financial position etc of a company. Various tools and methods are variable to evaluate the financial analysis of a company such as ratio analysis, vertical analysis, horizontal analysis etc. In this report, the main concern has been shown over the traditional methods and contemporary method of financial analysis and it has been evaluated that how both of these methods work and how does it assist the comapny to make a better decision about the position and the performance of the company. For traditional methods, ratio analysis, vertical analysis and horizontal analysis has been evaluated and for the contemporary methods, CAPM model, Dividend growth model and effective market hypothesise has been taken into the concern. These report briefs that how effective these analyses could be in evaluating the performance of a company. Critical review of traditional methods of financial analysis: The review over the traditional methods of the financial analysis is as follows: Horizontal analysis: Horizontal analysis is a form of analyzing the financial statement of the company on the basis of last year or months performance. In this analysis, an analyst could compare the performance of a month with the last months performance or a fiscal year. For instance, an organization has generated different revenues in different year than it could be compared through the horizontal analysis and it could be found that whether the revenues have been enhanced or it has been reduced from the last year (Jiashu, 2009). There are two methods to analyze the horizontal analysis of a company. First one is dollar analysis, in which the amounts of two different periods are compared. This statement helps a company to reach over a conclusion o reduce the level of the expenditure, second one is % analysis which depict that the performance of the business must be calculated on the basis of the %. Hillier, Grinblatt and Titman, 2011) Gapenski, (2008) has depicted in his study that horizontal analysis is one of the best technique to analyze the performance of a company. Further, it has been added by Dixon and Monk, (2009) that it is one of the simple technique to analyze the performance and the changes into the organization in a particular year. Zimmerman and Yahya-Zadeh, (2011) has briefed that due to this technology, it becomes easy for the company to manage the alternates the changes and it also assist the comapny to analyze the roots due to which the changes have occurred (Weston and Brigham, 2015). It assists the managers to make a better decision about the performance of the company. Further, it has been found that there are various shortcomings as well of this task which would manipulate the result and thus the decision making would also not be fair. According to the study of the Voelkl and Fritz, (2017), it has been found that the horizontal analysis manipulates the result and it do not offer the knowledge that why the changes have taken place and what are the main reasons behind these changes. Ward (2012) adds that it is a complex task to analyze and evaluate the base year for the study. Further, Weaver, Weston and Weaver, (2001) depicts that horizontal analysis is not useful in managing the price level challenge. It misleads the result of the financial analysis and thus it becomes tough for the organization to manage and make a better decision about the betterment of the company (Radebaugh, Gray and Black, 2006). Lastly, it has been found that horizontal analysis is a good technique to analyze the changes in terms of % in current year in the context of base y ear. Example: For instance, the study of horizontal analysis has been done over Admiral plc and Amec plc to analyze the impact of this study over the organization and decision of management and stakeholders of the company. This study depict that it is easy for the investors and the analysts to analyze the performance of the company. Further, it has been analyzed that it becomes important for the organization and the analyst to perform the study according to the rules and the norms to manage the performance of the company. From the study of horizontal analysis over both the companies, it became easy for the stakeholders and the management of the company to analyze the performance of the company and analyze the changes in current year according to the past year (Kinsky, 2011). Further, it has been found that the comparison study could also be easier. Form the study of Admiral Plc, it has been found that the performance of company in context of the figures of 2011 has been changed on a huge level. Currently the gross profit of the company is 33.92% of gross profit of 2011 which is quite higher than any other year. More, it has been found that the net profit of the company has also been 23.27% which is highest in last 5 years (Appendix). Through this study, it has been found that the performance of the company has also been enhanced. Further, the study has been done over the balance sheet of the company to analyze the performance of the company and changes in the financial figures of the company in last 5 years. From the study, it has been found that the level of total assets has been enhanced in 2015. Further, the total liabilities and total stakeholders equity depict that the various positive changes have taken place into the financial figures of the company which depict about the good performance of the company (Appendix). Form the study of Amec Plc, it has been found that the performance of company in context of the figures of 2011 has been changed on a huge level. Currently the gross profit of the company is 38.59% of gross profit of 2011 which is quite higher than any other year. More, it has been found that the net profit of the company has been -210.76% which is lowest in last 5 years (Appendix). Through this study, it has been found that various changes have taken place into the figures of the company in last 5 years. Further, the study has been done over the balance sheet of the company to analyze the performance of the company and changes in the financial figures of the company in last 5 years. From the study, it has been found that the level of total assets has been enhanced in 2015 (Appendix). Further, the total liabilities and total stakeholders equity depict that the various positive changes have taken place into the financial figures of the company which depict about the good performance of the company. Vertical analysis: Vertical analysis is a form of analyzing the financial statement of the company on the basis of various categories such as sales, assets, liabilities, cash flow etc. In this analysis, an analyst could compare the performance of a category according to the base category such as in balance sheet, the figures must be compared according to their base figure i.e. assets, liabilities and the total equity of the company. For instance, two or more companies of the same industry have been analyzed and the analysis has been done according to their net profit on the basis of their sales (Oliver and Schoff, 2017). Variance analysis works on assumptions that the analyzed companies would be of the same industry and all the data only bases over the basic figures. There is only one method to analyze the vertical analysis of a company. That is dollar analysis, in which the amounts of net profit would be compared to the sales of the company. This statement helps a company to reach over a conclusion to reduce the level of the expenditure and make a better analysis report about the performance of the company in comparison of the other company. (lord, 2007) Madhura (2011) has depicted in his study that vertical analysis is one of the best technique to analyze the performance of a company and compare the company with other companies in the same industry. Further, it has been added by Lacalle (2017) that it is one of the simple technique to analyze the comparative study and the performance of the company. Kaplan and Atkinson, (2015) has briefed that due to this technology, it becomes easy for the investors to analyze the different companies and make a better decision about the performance and the position of a company (Horngren, 2009). This analysis study helps the analyst and financial managers to identify the position and reach over a good decision. Further, it has been found that there are various shortcomings of the vertical analysis. Schlichting, (2013) depicted that the people who are at the bottom level feel demotivated due to vertical analysis in comparison of the upper chain. According to the study of the Phillips and Stawarski, (2016), it has been found that the vertical analysis takes a lot of time to reach over a final conclusion and it also makes the financial figures complex. Palicka, (2011) adds that it is a complex task to analyze and evaluate the performance and the position of the company in comparison of the competitive company (Madhura, 2014). Lastly, it has been found that vertical analysis is a good technique to analyze the changes in the financial figures of the company in comparison of the main base figure of the company. Example: For instance, the study of vertical analysis has been done over Admiral plc and Amec plc to analyze the importance and shortcomings of the vertical analysis in an organization. Further, it has been analyzed that it becomes important for the organization and the analyst to perform the study according to the rules and the norms to manage the performance of the company (Borio, 2016). From the study of vertical analysis over both the companies, it became easy for the stakeholders and the management of the company to analyze the performance of the company and analyze the changes in current year according to the past year. Further, it has been found that the comparison study could also be easier. Form the study of Admiral Plc, it has been found that the performance of company in context of gross profit has been better from last 5 years. Currently the gross profit of the company is 74.97% of total sales. More, it has been found that the net profit of the company has also been better in last 5 years. Through this study, it has been found that the performance of the company has also been enhanced. Further, the study has been done over the balance sheet of the company to analyze the performance of the company. From the study, it has been found that the total current assets of the company have been lowered in context of total assets in current year. Further, the study over liabilities and stakeholders equity depict that the various changes have taken place into the capital structure of the company. Form the study of Amec Plc, it has been found that the performance of company in context of gross profit has been bad from last 5 years. Currently the gross profit of the company is 12.25% of total sales which has been very less from last 5 years. More, it has been found that the net profit of the company has also been worst in last 5 years (Appendix). Through this study, it has been found that the performance of the company has been worst in last 5 years and company is supposed to make few changes into the performance. Further, the study has been done over the balance sheet of the company to analyze the performance of the company. From the study, it has been found that the total current assets of the company have been lowered in context of total assets in current year (Appendix). Further, the study over liabilities and stakeholders equity depict that the various changes have taken place into the capital structure of the company. Traditional ratio analysis: Traditional ratio analysis is a form of analyzing the financial statement of the company on the basis of various categories such as liquidity position, solvency position, profitability position, efficiency position etc. In this analysis, an analyst could compare the performance of a company according to the various categories such as in profitability position, the net profit of the company could be compared with the total sales of the company. For instance, two or more periods of a company have been analyzed and the analysis has been done according to their various financial figures (krantz, 2016). Traditional ratio analysis works on assumptions that other factors do not make an impact over the performance and stability position of a company. Mainly liquidity position, profitability position, solvency position, efficiency position etc are analyzed. This analysis helps a company to reach over a conclusion to make a better analysis report about the performance of the company. Following are some of the ratios and their formulas: Description Formula Profitability Net margin Net profit/revenues Return on equity Net profit/Equity Liquidity Current ratio Current assets/current liabilities Quick Ratio Current assets-Inventory/current liabilities Efficiency Receivables collection period Receivables/ Total sales*365 Payables collection period Payables/ Cost of sales*365 Asset turnover ratio Total sales/ Total assets Solvency Debt to Equity Ratio Debt/ Equity Debt to assets Debt/ Total assets (Kurth, 2013) Kinsky, (2011) has depicted in his study that ratio analysis is one of the oldest technique to analyze the performance of a company. Further, it has been added by Elton et al, (2009) that it is one of the simple technique to analyze the position of the company in various terms. Baker and Nofsinger, (2010) has briefed that due to this analysis method, it becomes easy for the investors to analyze the position of the company and make an investment decision (Ackert and Deaves, 2009). This analysis study helps the analyst and financial managers to identify the position and reach over a good decision. Further, it has been found that there are various shortcomings of the ratio analysis. Higgins, (2012) depicted that this analysis does not take a concern about the historical data. According to the study of the Glajnaric, (2016), it has been found that the ratio analysis study do not take a concern about various economical condition such as inflation rate to make a decision about the performance and changes into the company. Gitman and Zutter, (2012) adds that it is a complex task to analyze and evaluate the operational changes in the company. Further, Borio, (2013) depicts that accounting policies of a company also make an impact over the ratio analysis study. It misleads the result of the financial analysis and thus it becomes tough for the organization to manage and make a better decision about the betterment of the company. Example: For instance, the study of ratio analysis has also been done over Admiral plc and Amec plc to analyze the impact of this study over the organization and decision of management and stakeholders of the company. This study depict that it is easy for the investors and the analysts to analyze the performance of the company. Further, it has been analyzed that it becomes important for the organization and the analyst to perform the study on various basis to make better decision (Glajnaric, 2016). From the study of ratio analysis over both the companies, it became easy for the stakeholders and the management of the company to analyze the performance of both the companies and make a better decision about the performance of the company. Further, it has been found that the comparison study could also be easier. Firstly, the study of ratio analysis has been done over Admiral plc to analyze the changes and the performance of the company in last 5 years. The study has been done over working capital ratio and return on assets to analyze the changes which has taken place into the position of the company in last 5 years (Appendix). From the study, it has been found that the working capital ratio of the company has been 0.7638 in 2015 which was 0.3120 in 2011. It depict that the current situation of the liquidity of the company is better and it depicts that the level of current assets have been enhanced by the company to manage the level of the working capital. Further, the study has been done over the ratio return on assets to analyze the performance and the changes of the company. From this study, it has been found that the return on assets position of the company has been lowered from 2011 in 2015. Currently, the company is offering 21.53% return which is quite lesser than 33.28% in 2011 (Appendix). Further, the study has been done over the balance sheet of the company to analyze the performance of the company and changes in the financial figures of the company in last 5 years. From the study, it has been found that the level of total assets has been enhanced in 2015. Further, the total liabilities and total stakeholders equity depict that the various positive changes have taken place into the financial figures of the company which depict about the good performance of the company (Appendix). This depict that company is required to make some changes to enhance the level of return on assets. Lastly, the study of ratio analysis has been done over Amec plc to analyze the changes and the performance of the company in last 5 years. The study has been done over working capital ratio and return on assets to analyze the changes which has taken place into the position of the company in last 5 years. From the study, it has been found that the working capital ratio of the company has been 0.8279 in 2015 which was 1.6998 in 2011 (Appendix). It depict that the current situation of the liquidity of the company is better and it depicts that the level of current assets have been reduced by the company to manage the level of risk and cost of the company. Further, the study has been done over the ratio return on assets to analyze the performance and the changes of the company. From this study, it has been found that the return on assets position of the company has been lowered from 2011 in 2015. Currently, the company is offering 97.90% return which is quite lesser than 132.83% in 2011. This depict that still the position of return on assets of the company is better in market. Contemporary methods of financial analysis: Capital asset pricing model: Capital asset pricing model is the modern technology to identify and analyze the financial condition of a company. According to this study, it has been found that this model assist the investors to analyze the total return which is required while investing into the company. This technology mainly focuses over the risk factor and the return factor. This model depict that the return from an investment must be equal or more than the cost of capital of the company than only it would be profitable for the company (Zabarankin, Pavlikov and Uryasev, 2014). Investors could take the help of capital asset pricing method in evaluating and analyzing the attractiveness of the projected investments. This method is mainly used by the investors to make a well diversified portfolio so that the risk and return of the financial securities could be maintained. (Tsanakas and Millossovich, 2016) The above is the formula of the capital asset pricing method which evaluates about the total expected return from the securities. This formula depict that for analyzing the expected return, it is required for the investor to analyze the risk free rate of the country, market return of the industry, consumption beta etc. Tian Jiang, (2015) has depicted in his study that capital asset pricing method is one of the best technique to analyze the performance of the stock of a company. Further, it has been added by Seitzinger et al, (2010) that this study do not only take the concern of the internal figures such as ratio analysis do rather it takes a concern of the economy and market condition and make a better decision on the basis of that. Ross, Westerfield and Jaffe, (2007) has briefed that this modern analysis has made it very easy for the investors to analyze the total return which must be expected from a company while investing into the shares and debt of the company (Reilly and Brown, 2011). This analysis study helps the analyst and financial managers to identify the position and reach over a good decision. Further, it has been found that still few changes are required to done in the capital asset pricing model to make it better. Peterson and Fabozzi, (2002) depicted that the CAPM model takes a concern of the risk free rate. Risk free rate is the yield over the government securities which changes on the daily basis. According to the study of the Moles, Parrino and Kidwekk, (2011), it has been found that the CAPM has built over four assumptions which also include an unrealistic world picture. Lumby Jones, (2007) adds that it is a complex task to analyze and evaluate the beta of the company. Mainly, this model concerns about a proxy data and thus the outcome is unrealistic (Lee and Lee, 2006). Thus it becomes tough for the investors and the analyst to make a better decision about the investment and divestment from the company. Lastly, it has been found that capital asset pricing model analysis is a good technique to analyze the changes in the company and thus it becomes easy for the inve stors to invest into the company. Dividend growth model: Dividend growth model is also known as Gordon growth model. This model is the modern technology to identify and analyze the financial condition of a company. According to this study, it has been found that this model assist the investors to analyze the value of the expected dividends in the future. This technology mainly focuses over the time value of money (Damodaran, 2011). This model analyzes the current market price and future dividend of a company and makes a decision about the investment in the company according to that. Investors could take the help of dividend growth model in evaluating and analyzing the intrinsic value of a companys stock. This method is mainly used by the investors to analyze the worth of a security so that the best decision could be made. Dividend growth model could be calculated by using the below formula: Gordon Growth Model: stock price = (dividend payment in the next period) / (cost of equity - dividend growth rate) (Bornholt, 2013) The above is the formula of the dividend growth model which evaluates about the total worth of a companys stock. This formula depict that for analyzing the price of a stock of a company, it is required for the investor to analyze the last dividend payment, current growth rate of the dividend and equity cost of the company. Batra and verma (2004) has depicted in his study that dividend growth method is one of the new and modern technique to analyze the performance and the worth of the stock of a company. Further, it has been added by Barlow, (2006) that this study evaluates the worth of the stock price of a company which also takes the concern of the market condition so that the comparison of the company could be easy with the competitors and industry. Fulin (2011) has briefed that this modern analysis has made it very easy for the investors to analyze the total worth of the equity of the company so that the best value could be recognized and the decision could be made according to that (FIRRER et al, 2012). This analysis study helps the analyst and financial managers to identify the position and reach over a good decision. Further, it has been found that still few changes are required to done in the dividend growth model to make it better. Elmuti and Kathawala, (2001) depicted that the dividend growth model do not takes a concern of the non dividend factor like brand loyalty. Customer retention and intangible assets are also not recognized by this method, but these values enhance the worth of the business. According to the study of the Du and Girma, (2009), it has been found that the dividend growth model mainly express that the growth rate of the dividend of a company always stables and known but in reality, it fluctuates rapidly. Deegan (2013) adds that it is a complex task to analyze and evaluate the intrinsic value of the stock of a company. Mainly, this model concerns about a proxy data and thus the outcome is unrealistic (Davies and Crawford, 2011). Thus it becomes tough for the investors and the analyst to make a better decision about the investment and divestment from the company. Lastly, it ha s been found that dividend growth model analysis is a good technique to analyze the worth of the company. Effective market hypothesis: Effective market hypothesis is the modern and best technology to identify and analyze the financial condition of a company. According to this study, it has been found that EMH theory express that it is not easy for the inventors to beat the market as the market efficiency of the security market causes the already existed share prices incorporate and express about all the relevant information. This analysis depict that the security market always deals of the stock on their fair value so that it becomes impossible for the investors to buy the stock in lower prices (Davies and Crawford, 2011). This model analyzes that it is not possible that entire market is wither performing very good or very bad collectively. This rule could be applied over a single security. Investors could take the help of EMH in evaluating and analyzing the market position. This method is mainly used by the investors to analyze the worth of a company. The EMH theory performs according to the 3 division of a result which is strong, semi strong and weak. This formula depict that for analyzing the worth of a company, it is required for the investor to analyze the various economical and market position as well as the policies and the strategies of the company (CORRERIA et al, 2012). Bui et al, (2016) has depicted in his study that effective market hypothesis is one of the new and modern technique to analyze the performance and the worth of the company. Further, it has been added by Bromwich and Bhimani, (2005) that this study evaluates the worth of a company and for which they also takes the concern of the market condition so that the comparison of the company could be easy with the competitors and industry. Brigham and Michael (2013) has briefed that this modern analysis has made it very easy for the investors to analyze the total worth of the company so that the best value could be recognized and the decision could be made according to that (Brigham and Houston, 2012). This analysis study helps the analyst and financial managers to identify the position and reach over a good decision. Further, it has been found that still few changes are required to done in the effective market hypothesis theory to make it better. Brealey et al, (2007) depicted that the EMH do not takes a concern of the various important factors. According to the study of the Borio (2014), it has been found that the EMH theory is based over various assumptions. Amold (2013) adds that it is a complex task to analyze and evaluate the worth of a company. Mainly, this model concerns about a proxy data and thus the outcome is unrealistic (Brigham and Ehrhardt, 2013). Thus it becomes tough for the investors and the analyst to make a better decision about the investment and divestment from the company. Lastly, it has been found that EMH analysis is a good method to analyze the worth of the company. Conclusion: To conclude, horizontal analysis is used to evaluate the performance of the comapny on the context of last year. Further, vertical analysis and ratio analysis is used to evaluate the performance of the comapny with the industry position and on the basis of various positions respectively. More, the modern technologies depict that the CAPM method helps the investors to analyze the return from the investment. Dividend growth model helps the company to analyze the worth of the security and EMH helps in analyzing the worth of a company. The best financial analysis method is EMH theory as it takes a concern of all the relevant factor and depict a good result. References: Ackert, L. and Deaves, R. 2009.

Computer Crime Essays (3095 words) - Software, System Software

Computer Crime Computer Crime It's the weekend, you have nothing to do so you decide to play around on your computer. You turn it on and then start up, you start calling people with your modem, connecting to another world, with people just like you at a button press away. This is all fine but what happens when you start getting into other peoples computer files. Then it becomes a crime, but what is a computer crime really, obviously it involves the use of a computer but what are these crimes. Well they are: Hacking, Phreaking, & Software Piracy. To begin I will start with Hacking, what is hacking. Hacking is basically using your computer to Hack your way into another. They use programs called scanners which randomly dials numbers any generating tones or carriers are recorded. These numbers are looked at by hackers and then used again, when the hacker calls up the number and gets on he's presented with a logon prompt, this is where the hacking really begins, the hacker tries to bypass this anyway he knows how to and tries to gain access to the system. Why do they do it, well lets go to a book and see Avid young computer hackers in their preteens and teens are frequently involved in computer crimes that take the form of trespassing, invasion of privacy, or vandalism. Quite often they are mearly out for a fun and games evening, and they get entangled in the illegal use of their machines without realizing the full import of what they are doing, I have a hard time believing that so lets see what a hacker has to say about what he does Just as they were enthraled with their pursuit of information, so are we. The thrill of the hack is not in breaking the law, it's in the pursuit and capture of knowledge., as you can see the hacker doesn't go out to do destroy things although some do. It's in the pursuit of knowledge. Of course this is still against the law. But where did all of this start, MIT is where hacking started the people there would learn and explore computer systems all around the world. In the views of professional hacking is like drugs or any other addictive substance, it's an addiction for the mind and once started it's difficult to stop. This could be true, as hackers know what they are doing is wrong and they know odds are they will be caught. But as I mentioned some hackers are just above average criminals, using there skills to break in banks and other places where they can get money, or where they can destroy information. What a hacker does at a bank is take a few cents or even a few fractions of a cents from many different accounts this may seem like nothing but when all compiled can be alot. A stick up robber averages about $8,000 each job, and he has to put his life and personal freedom on the line to do it while the computer hacker in the comfort of his own living room averages $500,000 a job. As for people destroying information, this is for taking some one down, destruction of data could end a business which for some is very attractive. It can cost a company thousands of dollars to restore the damage done. Now that you have an understanding of what a hacker is, it time to move on to someone closely associates with a hacker. This is a Phreak, but what is that. For the answer we turn to the what is known as the Official Phreakers Manual Phreak [fr'eek] 1. The action of using mischievous and mostly illegal ways in order to not pay for some sort of telecommunications bill, order, transfer, or other service. It often involves usage of highly illegal boxes and machines in order to defeat the security that is set up to avoid this sort of happening. [fr'eaking] v. 2. A person who uses the above methods of destruction and chaos in order to make a better life for all. A true phreaker will not go against his fellows or narc on people who

Everglades Flooding Essays - Everglades, Free Essays, Term Papers Everglades Flooding The Everglades: Florida's Dying Natural Wonder Perhaps we take it for granted that our beautiful homeland will be forever changed because of the effects of modern civilizations. The environment, local animals, plants, and neighboring niches are all being affected by a few factors. The insensitivity of humans towards our fellow living creatures has caused the Everglades to shrink dramatically in the last one hundred years. The health of the everglades has been compromised because we as humans need more space to live on, bigger roads, and adventures on which we embark. In the following paragraphs, I will explain one of the most threatening factors to Florida's Everglades, habitat loss. Originally, the Everglades consisted of nearly 8,100 square miles, now, it has been reduced to about 2,300 square miles of which about three-fifths is in set-designated water conservation areas. Two-thirds of the original everglades is the water that falls on one-thirds of the original watershed. In simpler terms, the water in the Everglades is being washed into the ocean at a faster rate than the animal and plant life can adapt to. If this problem continues on the same route it is on, the death toll of animals and plants will reach catastrophic proportions. Many years ago, the Everglades was much deeper than it is now and the wet season lasted many months. Now, huge amounts of water come in short intervals and are dried up more quickly than it can be replaced due to drainage. Grasses who survive in deep water are being killed rapidly. Due to the death of these grasses, several species of fish have decreased dramatically in number. The loss of these grasses allows the melalueca to dominate these areas as the supreme species of plants. Fourteen animal species in the everglades are endangered and many more are threatened. The loss of habitat and overcrowding of certain species are disturbing animal population. Since the 1900's, ninety percent of the bird population has died. In 1988 a serious drought left many animal species homeless and many dead. Food loss due to lack of water killed many plant species. By 1989, only 5,000 bird nests and 15 colonies were present in the watershed of the everglades. In only one year, that number dropped to 1,000 nests. As we all know and love, the food web explains how countless animal and plants are co-dependents of each other and how the domino effect can change each and every one of those species. Many conservation efforts have been done to save the everglades, yet they have all failed miserably in a feeble attempt to erase the damage cause by the most abundant predator to any species world wide, mankind. The Everglade Agriculture Area has been set up to enrich the soil in the Everglades, hopefully restoring the animal and plant life to the original numbers that they used to be. When the water levels plummet and new nutrients are added, the soil is exposed to large amounts of oxygen. This speeds up the bacterial growth and can further harm plant life. The soil can then turn to fine dust and lower the water level several feet. Another effort to save the everglades it to kill the melalueca trees, which suck up large quantities of water. Cutting down the trees was first attempted, but that effort further spread the melalueca seeds. Another method was tried, poison. Poisons are being developed to kill small islands of melalueca trees with out harming the neighboring plants. Everyone can agree on one thing, the distribution of melalueca trees in the Everglades by humans is one of the worst ideas to plague the Everglades epidemic. Overall, vast amounts of money have been spent to save the Everglades. The Clinton administration has donated 1.5 billion dollars on conservation efforts. The 13 billion-dollar tourism industry to the Everglades and the Keys has helped with funds for the Everglades Wildlife Fund and other organizations. On average, the amount of money donated per year to Everglade's conservation efforts is about 2 billion dollars. The reason I chose to do this report on the Everglade is because I got an offhand look at how the Everglades is being destroyed slowly. While going on an airboat tour of the Everglades,

Ethics Critique Essay Example | Topics and Well Written Essays - 1000 words - 1

Ethics Critique - Essay Example According to psychological research, moral judgments are shaped by the human mind and behavior (Ross, et al.345). On the same note, moral judgments are influenced by what a person perceives to be right or wrong. In this respect, the issues of ethics moral, norms, and ethics emerge. These three issues vary from one person to another for differentiated reasons, among them individual growth and development, cultural effects, and the impact of the society on an individual. Therefore, based on the work of the mind and the underlying human behavior, a person can make moral judgments that do not necessarily match those that might be made by another person. Psychological research essentially explains how human beings make moral judgments, based on the human mind and behavior (Ross, et al.358). The right or wrong factor at an individual level is accounted for, alongside virtues and ethics that are also based on the human mind and behavior. The link between all the aforementioned variables can help in explaining the thoughts, judgments, or actions that an individual, or society for that matter, undertakes regarding any given situation or condition. In this respect, judgments or actions by human beings can be justified through psychological research. In understanding how human beings act, feel, and think prior to making moral judgments, psychological research factors in a number of variables that influence the whole process. To start with, human beings must be aware of some given form of morals in order to enable them make moral judgments. In other words, they must be in a good position to distinguish between right and wrong. This aspect is shaped by the environment, behavior, culture, and society among other variables. Once the human being is potentially in a position to differentiate right and wrong, the issue of moral

FINAL PAPER Essay Example | Topics and Well Written Essays - 2500 words

FINAL PAPER - Essay Example ating phenomenon to mankind, the very essence of our existence and the ability for an individual to ponder reflectively on his/her life has been a puzzle to all generations, the problems of identity exist because we exist, on the same concept, the problems emanate from our natural awareness and inquisitiveness, firstly, our identity is directly attached to our personhood, but the question arises, what is a person? The answer most probably must mention some several key activities like locomotion and reproduction, Locke argued that a person is an organism that possess mental capability, Descartes, in his famous quote, I think, therefore I am also directly mentions the faculty of thought, but the challenge arises when we cannot prove whether other ‘things’ have similar capabilities as we do, for example cattle that possess locomotive and reproduction abilities, another question ensues with this issue in that we must wonder- do these other ‘things’ think as we do? And if they do, do they possess an identity as we do. Computers are capable of doing analytical tasks at a speed faster than an individual-so, does it think? So with such matters, it is not a simple task to draw a line between a person and a non person. Besides, it is a reasonable question to ask oneself, when does one become a person, and what would cause him to cease to be? If a person is an organism that possesses mental capability, where do we classify the lunatic or a fetus? No wonder there have been very controversial debates on abortion as some perceive a fetus as a non person while others perceive a fetus as a living organism. The debate further boils to when does life (person) begin, at birth or during conception? Personhood therefore can be clearly defined especially after considering other intelligent animals and automated robots and that are capable of imitating almost everything that we can do, unless we accept the common definition that a person is a human being. This definition

Quality Management Assignment - The assignment is based on the Eurocab Essay

Quality Management Assignment - The assignment is based on the Eurocab case study and appendices attached. Study the case and an - Essay Example One way of achieving both efficiency and effectiveness is through quality management which can be done using the total quality management (TQM) model. TQM is an organisational culture devoted to customer satisfaction through an integrated system of tools, techniques and training aimed at the continuous improvement of the products and services offered (Kotler & Armstrong, 2004). As such, this essay seeks to carry out a critique of EuroCab’s current approach to quality and how this compares with Crosby's fourteen point plans. The analysis will highlight the aspects of the plan being implemented as well as outline the points missed. The second part of the essay will look at the extent to which the six sigma methodology can be implemented within the organisation. 1. EuroCab is one of the leading European manufacturers of customised metal cabinets of various sizes and designs. These are sold to different customers to contain, support and securely protect electrical and electronic c ontrol systems from damage. However, the operations of this organisation are geared towards productivity and there are quality concerns since some of the products manufactured do not conform to the expected standards. Quality of a product or service is based on the judgement by the individual or organisation of a particular product with regards to benefits, value or satisfaction that can be derived from using it (Kotler & Armstrong, 2004). Organisations that are concerned about their viability should prioritise the aspect of quality in order to gain a competitive advantage. As noted, the aspect of quality is of concern to Eurocab and this section of the essay seeks to critique the company's current approach to quality and how this compares with Crosby's fourteen point plan. Philip B Crosby is a quality guru and is known for the concepts of â€Å"Quality is Free† and â€Å"Zero Defects. There are four absolutes of quality in his quality improvement process which are: Quality is conformance to requirements, the system of quality is prevention, the performance standard is zero defect and the measurement of quality is the price of non-conformance. Details of quality gurus can be viewed at the Department of Trade and Industry’s website at . His model is comprised of fourteen steps and these are going to be used to analyse the company’s current approach to quality. He suggests that the first step is that management should be committed to a formalised quality policy but in this case, it seems there is no such coordination between the management and the other members of the organisation in other departments. The management is primarily concerned with productivity while at the same time quality related issues are neglected. The blame for any faulty cab is given to the Quality, Manufacturing as well as the Electrical assembly departments. The management does not make follow up on its quality policies to ensure that that there is conformity in the o perations of the organisation as a whole to satisfy the quality needs of the customers as well as the company. The second aspect of Cosby’s 14 steps is the formation of a management level quality improvement team (QIT) with responsibility for quality improvement process planning and administration. As such, it can be noted that EuroCab has

Introduction To Rdbms Oodbms And Ordbms Information Technology Essay

Introduction To Rdbms Oodbms And Ordbms Information Technology Essay The relational model is based on the structure of a database. A database is simply a collection of one or more relations or tables with columns and rows. The use of set theory allows for data to be structured in a series of tables that has both columns and rows. Each column corresponds to an attribute of that relation, while each row corresponds to a record that contains data values for an entity. The main elements of RDBMS are based on Ted Codds 13 rules for a  relational system, the concept of relational integrity, and normalization. The three fundamentals of a relational database are that all information must be held in the form of a table, where all data are described using data values. The second fundamental is that each value found in the table columns does not repeat. The final fundamental is the use of Standard Query Language (SQL). Benefits of RDBMS are that the system is simple, flexible, and productive. Because  the tables are simple, data is easier to understand and communicate with others. RDBMS are flexible because users do not have to use predefined keys to input information. Also,  RDBMS are more productive because SQL is easier to learn. This allows users to spend more time  inputting instead of learning. More importantly, RDBMSs biggest  advantage is the ease with which users can  create and access data and extend it if needed. After the original database is created, new data categories can be added without the existing application being changed. There are limitations to the relational database management system. First, relational databases do not have enough storage area to handle data such as images, digital and audio/video. The system was originally created to handle the integration of media, traditional fielded data, and templates. Another limitation of the relational database is its inadequacy to operate with languages outside of SQL. After its original development, languages such as C++ and JavaScript were formed. However, relational databases do not work efficiently with these languages. A third limitation is the requirement that information must be in tables where relationships between entities are defined by values. Today, the relational model is the dominant data model as well as the foundation for the leading DBMS products, which include IBMs DB2 family, Informix, Oracle, Sybase, Microsofts Access and SQLServer, as well as FoxBase and Paradox. RDBMS represent close to a multibillion-dollar industry alone. To combat the limitations of RDBMS and meet the challenge of the increasing rise of the Internet and the Web, programmers developed object-oriented databases in the 1980s. The main objective of Object-Oriented Database Management Systems, commonly known as OODBMS, is to provide consistent, data independent, secure, controlled and extensible data management services to support the object-oriented model. They were created to  handle big and complex data that relational databases could not. There are important characteristics involved with object-oriented databases. The most important characteristic is the joining of object-oriented programming with database technology, which provides an integrated application development system. Object-oriented programming results in 4 main characteristics:  inheritances, data encapsulation, object identity, and polymorphism. Inheritance allows one to develop solutions to complex problems incrementally by defining new objects in terms of previously defined objects. Data encapsulation or simply encapsulation allows the hiding of the internal state of the objects. Encapsulated objects are those objects that can only be assessed by their methods instead of their internal states. There are three types of encapsulated objects users and developers should recognize. The first is full encapsulation, in which all the operations on objects are done through message sending and method execution. The second is write encapsulation, which is where the internal state of the object is visible only for reading operations. The third is partial encapsulation, which involves allowing direct access for reading and writing for only a part of the internal state. Object identity allows objects of the database to be independent of each other. Polymorphism and dynamic binding allow one to define operations for one object and then to share the specification of the operation with other objects. This allows users and/or programmers to compose objects to provide solutions without having to write code that is specific to each object. The language important to OODBMS is data definition and manipulation language (DDML). The use of this language allows persistent data to be created, updated, deleted, or retrieved. An OODBMS needs a computational versus a relational language because it can be used to avoid impedance mismatch. DDML allows users to define a database, including creating, altering, and dropping tables and establishing constraints. DDMLs are used to maintain and query a database, including updating, inserting, modifying, and querying data. The OODBMS has many advantages and benefits. First, object-oriented is a more natural way of thinking. Second, the defined operations of these types of systems are not dependent on the particular database application running at a given moment. Third, the data types of object-oriented databases can be extended to support complex data such as images, digital and audio/video, along with other multi-media operations. Different benefits of OODBMS are its reusability, stability, and reliability. Another benefit of OODBMS is that relationships are represented explicitly, often supporting both navigational and associative access to information. This translates to improvement in data access performance versus the relational model. Another important benefit is that users are allowed to define their own methods of access to data and how it will be represented or manipulated. The most significant benefit of the OODBMS is that these databases have extended into areas not known by the RDBMS. Medicine, multimedia, and high-energy physics are just a few of the new industries relying on object-oriented databases. As with the relational database method, object-oriented databases also has disadvantages or limitations. One disadvantage of OODBMS is that it lacks a common data model. There is also no current standard, since it is still considered to be in the development stages. Object-oriented database technology is a marriage of object-oriented programming and database technologies. Figure 1 illustrates how these programming and database concepts have come together to provide what we now call object-oriented databases. Introduction to RDBMS OODBMS and ORDBMS Perhaps the most significant characteristic of object-oriented database technology is that it combines object-oriented programming with database technology to provide an integrated application development system. There are many advantages to including the definition of operations with the definition of data. First, the defined operations apply ubiquitously and are not dependent on the particular database application running at the moment. Second, the data types can be extended to support complex data such as multi-media by defining new object classes that have operations to support the new kinds of information. Other strengths of object-oriented modeling are well known. For example, inheritance allows one to develop solutions to complex problems incrementally by defining new objects in terms of previously defined objects. Polymorphism and dynamic binding allow one to define operations for one object and then to share the specification of the operation with other objects. These objects can further extend this operation to provide behaviors that are unique to those objects. Dynamic binding determines at runtime which of these operations is actually executed, depending on the class of the object requested to perform the operation. Polymorphism and dynamic binding are powerful object-oriented features that allow one to compose objects to provide solutions without having to write code that is specific to each object. All of these capabilities come together synergistically to provide significant productivity advantages to database application developers. A significant difference between object-oriented databases and relational databases is that object-oriented databases represent relationships explicitly, supporting both navigational and associative access to information. As the complexity of interrelationships between information within the database increases, so do the  advantages of representing relationships explicitly. Another benefit of using explicit relationships is the improvement in data access performance over relational value-based relationships. A unique characteristic of objects is that they have an identity that is independent of the state of the object. For example, if one has a car object and we remodel the car and change its appearance, the engine, the transmission, and the tires so that it looks entirely different, it would still be recognized as the same object we had originally. Within an object-oriented database, one can always ask the question, is this the same object I had previously?, assuming one remembers the objects identity. Object-identity allows objects to be related as well as shared within a distributed computing network. All of these advantages point to the application of object-oriented databases to information management problems that are characterized by the need to manage: a large number of different data types,   a large number of relationships between the objects, and   objects with complex behaviors. Application areas where this kind of complexity exists includes engineering, manufacturing, simulations, office automation and large information systems. Object-Relational database (ORDBMS) is the third type of database common today. ORDBMS are systems that attempt to extend relational database systems with the functionality necessary to support a broader class of applications and, in many ways, provide a bridge between the relational and object-oriented paradigms. ORDBMS was created to handle new types of data such as audio, video, and image files that relational databases were not equipped to handle. In addition, its development was the result of increased usage of object-oriented programming languages, and a large mismatch between these and the DBMS software. One advantage of ORDBMS is that it allows organizations to continue using their existing systems, without having to make major changes. A second advantage is that it allows users and programmers to start using object-oriented systems in parallel. There are challenges in implementing an ORDBMS. The first is storage and access methods. The second is query processing, and the third is query optimization. Since the development of RDBMS, OODBMS, and ORDBMS, many vendors have extended their systems with the ability to store new data types such as images and texts, and with the ability to ask more complex queries. One rising technique is enterprise resource planning and management resource planning, which add another layer of application-oriented features on top of a DBMS. Included applications come from  Baan, Oracle, SAP, and Siebel. These programs each identify a set of common tasks encountered by a large number of organizations and provide a general application layer to carry out these tasks. More importantly, DBMS have advanced into the Internet and Web Age.  Stored data is widely being accessed through a Web browser. Today, queries are being generated through Web-accessible forms and answers are being formatted using a mark-up language such as HTML. In addition, many vendors and distributors are adding features to their DBMS aimed at making it better equipped for Internet usage. In summary, relational and object-oriented database systems each have certain strengths as well as certain weaknesses. In general, the weakness of one type of system tends to be strength of the other. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦. Object Relational Database Management  System  (ORDBMS) is a DBMS or Database Management System akin to a relational database, but with an object oriented database model that allows  custom web development  professionals to combine the database with custom data types. It bridges the gap between relational databases and Object-Oriented Database Management System (OODBMS).   Traditional RDBMS (Relational Database Management System) focused on the efficient management from a limited set of data-types. Object relational DBMS allows  web sites development  experts to combine their own data types and methods.   The limitations of RDBMS have led to the introduction of object-relational database management systems ORDBMS systems occurred in the early 1990s out of research. One of the most notable research projects, the Postgres introduced two products Illustra and Postgre SQL. The mid-1990s saw many commercial products appearing. These included Omniscience, UniSQL and Illustra 2.   Objectives of Object Relational Databases: To bridge the gap between object-relational mapping and conceptual data modeling techniques. To bridge the gap between object oriented modeling techniques (used in programming languages like C++, C# and  Java) and relational databases. Advantages of ORDBMS: Object Relational Database Management Systems ensures large storage capacity, which is an important part in web based  development The access speed is fairly quick. ORDBMSs have massive scalability. ORDBMSs boast excellent manipulation power of object databases. Supports object functionality by adding separate APIs and  server  subsystems Redesigns the database engine completely Supports rich data types by adding a new object-oriented layer. Apart from these benefits, an object relational database management system has some drawbacks. One of the major disadvantages is its incapability for high-speed internet applications. However, ORDBMSs are designed to manage large amounts of information, an important aspect in the  development of website. The IDC opines that the ORDBMS market has the potential to surpass the size of ODBMS in the next couple of years in web based development.

An object relational database is also called an object relational database management system (ORDBMS). This system simply puts an object oriented front end on a relational database (RDBMS). When applications interface to this type of database, it will normally interface as though the data is stored as objects. However the system will convert the object information into data tables with rows and colums and handle the data the same as a relational database. Likewise, when the data is retrieved, it must be reassembled from simple data into complex objects. Performance Constraints Because the ORDBMS converts data between an object oriented format and RDBMS format, speed performance of the database is degraded substantially. This is due to the additional conversion work the database must do. ORDBMS Benefits The main benefit to this type of database lies in the fact that the software to convert the object data between a RDBMS format and object database format is provided. Therefore it is not necessary for programmers to write code to convert between the two formats and database access is easy from an object oriented computer language. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ To define Object-Relational Database Management System (ORDBMS) it is enough to take simple equation: ORDBMS = ODBMS + RDBMS = (O + R) * DB * MS. On a logical level, an ORDBMS is the MS process methods applied for DB data structure, which is complied with O object and R relational concepts. The R relational concept in the context of DBMS is based on the relations in the form of two-dimensional tables of rows and columns. Transformation of queries into relational algebra is the main confirmation that affiliates a database with the relational model. It is prejudice to think that SQL2 language is a single and necessary criterion of RDBMS just as to think that Java is a single language of OO programming. Noteworthy feature of RDBMS is the possibility to process a large mass of the uniform n-element tuples (rows or records) quickly. All necessary for object representation is available in the object DBMS (ODBMS). Often the ODBMS is equated to the OODBMS, namely DBMS integrated with an Object-Oriented (OO) programming language like C++ and Java. The characteristic properties of ODBMS are 1)  complex data, 2)  type inheritance, and 3)  object behavior. These features will be considered below regarding the ORDBMS. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ Complex data creation in most SQL ORDBMSs is based on preliminary schema definition via the user-defined type (UDT). The table remains a most clear form for representation of complex data in any ORDBMS. students id name course first last st031 Jane Hunter Economy Planning st072 Richard White Computers in Engineering The name attribute (or field or column) consists of the first and last attributes. The value of the course attribute is a set of Economy and Planning elements. Such structure is able, for example, for the Informix SQL (http://www-3.ibm.com/software/data/informix/pubs/library/index.html). CREATE ROW TYPE Student (      id CHAR(5),      name ROW (first VARCHAR(12), last VARCHAR(20)),      course SET (VARCHAR(128) NOT NULL)   );   CREATE TABLE students OF TYPE Student;   INSERT INTO students   VALUES (      st031,      ROW(Jane, Hunter),      SET(Economy, Planning)   );   INSERT INTO students   VALUES (      st072,      ROW(Richard, White),      SET(Computers in Engineering) ); Other SQL ORDBMS suggests other composite type constructors, for example VARRAY or ARRAY instead of the SET, and OBJECT instead of the ROW. Constructors of the simple built-in types, with limitations like CHAR(5), came from SQL2. Is it necessary to define schema before filling a database? Historically, the answer was canonical yes for two reasons. Firstly, the definition of database schema essentially helped to control the type of input data. Secondly, the data type limitation made possible the early DBMSs to organize data with maximal memory and processor efficiency. Nevertheless, development of database schema is a most laborious process. There are a lot of situations related with complex data when precise schema description is not necessary or unreasonably slows project development. Furthermore, both reasons for schema predefinition are no longer valid. Control of input data should be executed by supporting an input form, (e.g., via JavaScript on the Web client side). With the hardware advances in modern database systems, the influence of data type limitation on performance is practically insignificant. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ An object-oriented database management system (OODBMS), sometimes shortened to  ODBMS  for  object database management system), is a database management system (DBMS) that supports the modelling and creation of data as  objects. This includes some kind of support for  classes of objects and the  inheritance  of class properties and  methods by subclasses and their objects. There is currently no widely agreed-upon standard for what constitutes an OODBMS, and OODBMS products are considered to be still in their infancy. In the meantime, the object-relational database management system (ORDBMS), the idea that object-oriented database concepts can be superimposed on relational databases, is more commonly encountered in available products. An object-oriented database interface standard is being developed by an industry group, the Object Data Management Group (ODMG). The Object Management Group (OMG) has already standardized an object-oriented data brokering interface betwee n systems in a network. In their influential paper,  The Object-Oriented Database Manifesto, Malcolm Atkinson and others define an OODBMS as follows: An object-oriented database system must satisfy two criteria: it should be a DBMS, and it should be an object-oriented system, i.e., to the extent possible, it should be consistent with the current crop of object-oriented programming languages. The first criterion translates into five features: persistence, secondary storage management, concurrency, recovery and an ad hoc query facility. The second one translates into eight features: complex objects, object identity, encapsulation, types or classes, inheritance, overriding combined with late binding, extensibility and computational completeness. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦.. http://www.versant.com/en_US/products/oodbms.html/ OODBMS (OBJECT DATABASE) ADVANTAGES Using an  OODBMS  /  ODBMS  (object database management system, object-oriented data management system) for data storage brings powerful advantages to applications that use complex object models, have high concurrency requirements, and large data sets. It is difficult, time consuming, expensive in development, and expensive at run time, to map the objects into a relational database and performance can suffer. Versantsobject database  solutions (ODBMS) are designed to handle the navigational access, seamless data distribution, and scalability often required by these applications: Versant Object Database  OODBMS  (Java,  C++) FastObjects .NET  OODBMS  (.NET) Why Versants  OODBMS  solutions instead of traditional RDBMS? Where data handling requirements are simple and suitable to rigid row and column structures an RDBMS might be an appropriate solutiuon. However,for many applications, todays most challenging aspect is controlling the inherent complexity of the subject matter itself the complexity must be tamed. And tamed in a way that enables continual evolution of the application as the environment and needs change. For these applications, an  OODBMS  is the best answer: COMPLEX (INTER-) RELATIONSHIPS If there are a lot of many-to-many relationships, tree structures or network (graph) structures then Versants  OODBMS  solutions will handle those relationships much faster than a relational database. COMPLEX DATA For many applications, the most challenging aspect is controlling the inherent complexity of the subject matter itself the complexity must be tamed. For these applications, a Versant  OODBMS  is the best answer. Architectures that mix technical needs such as persistence (and SQL) with the domain model are an invitation to disaster. Versants  OODBMS  solutions let you develop using objects that need only contain the domain behaviour, freeing you from persistence concerns. NO MAPPING LAYER It is difficult, time consuming, expensive in development, and expensive at run time, to map the objects into a relational database and performance can suffer. VersantsOODBMS  solutions store objects as objects yes, its as easy as 1, 2, 3. Versants object database solutions are designed to store many-to-many, tree and network relationships as named bi-directional associations without having the need for JOIN tables. Hence, Versants object database solutions save programming time, and objects can be stored and retrieved faster. Modern O/R mapping tools may simplify many mapping problems, however they dont provide seamless data distribution or the performance of Versants  OODBMS  solutions.
