Database Design Paper Essays - Free Essays, Term Papers Database Design Paper ?A database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of records well, but be accessed easily. In addition, new information and changes should also be fairly easy to input.? (tech-faq.com); to ensure usefulness over the long-term, databases should be built with high data integrity and the ability to recover data if the hardware fails. Information that has been corrupted or destroyed serves no purpose within a business structure. Being the Armed Forces is like being a field value in one giant database. Everything from the gear we are issued to how we are identified as an ?individual? (ssn#) is a scannable number to be coded, referenced, and utilized by anyone with proper clearance. ?The database architecture is the set of specifications, rule, and processes that dictate how data is stored in a database and how data is accessed by components of the system.? (wingenious.com) Database architecture type s can be broken down into three broad categories, each of which can have several subcategories: One Tier, Two Tier- client/server, and ?N? Tier- client/server. The One Tier architecture is best suited to the single user and relatively small amounts of data. It runs on the user?s local machine and references a file that is stored on that machine?s hard drive, thus using a single physical resource to access and process information. For multiple users and small scale applications Two Tier client/server architecture would be better suited than One Tier architecture. Users interact through a GUI (graphical user interface) to communicate with the database server across a network via SQL (structured query language. For the large scale applications, ?N? Tier client/server architecture must be adopted. The client/server model expands to include a middle (or business) tier, which is an application server that houses the business logic. The middle tier translates client calls into database queries as well as translating data from the database into client data in return. The client and server never actually talk to one another directly. (windowsecurity.com) The database architecture I use at work, I would qualify as ?N? Tier client/server architecture. When entering or leaving base, all military personal must have their IDs scanned. This information is checked against a central database by going through a middle tier to prevent direct contact with the military mainframe, both for security and volume reasons. In a relational database, the data in different tables is mapped with relations. ?Information can be accessed or added without reorganizing the tables. A table can have many records and each record can have many fields? (tech-faq.com). Unlike flat databases, data integrity is built into the model at various levels to ensure the accuracy of the data, that the records are not duplicated, and that the relationship between a pair of tables is valid. (dewey.library.nd.edu) Microsoft Access does a great job of reinforcing referential integrity with a strong normalization protocols that ensure table definitions and informational relationships.

buy custom Hamlet as a Tragic Hero essay

buy custom Hamlet as a Tragic Hero essay Shakespeare presents Hamlet as a tragic hero. He has smart traits to qualify to be a hero. For example, this character is daring and brave. This is portrayed by the fact that he takes a high risk by going to England. In case his plan failed, this character would be executed in England. Hamlet also comes out as a loyal person in that he remains loyal to his father. He gets angry because of his fathers death and, thus he remains angry at his mother and Claudius for killing his father. Hamlet also comes out as an intelligent person when he pretends to be insane to be able to gather the necessary information regarding Claudius. He, however, had a flaw since he could not move on whenever he wanted. Hamlet continued attending school even as an adult for failure to move on with life. It also took him a long time to stop grieving his fathers death simply because he could not move past that. Finally, when he managed to stop grieving, Hamlet could not kill Claudius. He continued to pretend that he was mad even after confirming that Claudius caused his fathers death. Hamlet could not accomplish many things. He did not marry Ophelia even after dating her for a long time. The audience pities Hamlet for his parents death, and the fact that he loved his parents such that he became hurt by the changes that took place. Hamlets failure to move over one thing led to his death. He is killed using a poisoned sword. He had several opportunities to deal with Claudius but he made a decision being a tragic hero. The tragedy of Hamlet is an enigma. At one time, Hamlet should kill the king, but the play portrays him as a failure since he is unable to kill him. Some people argue that Hamlet failsto revenge because his inner feelings do not permit him. He seems to be weak willed. It could also be that the task placed on his shoulders was heavy for him. Other critics argue that Shakespeare wanted to show tragedy of a person who is weak willed, and at the same time poorly equipped. Other critics argue that Hamlet fails to kill the king because of the obstacles he comes across as he tries to accomplish his goal. Opposition from the king and his people makes proves difficult to kill the king at once. These critics believe that Hamlets aim was not to kill the king, but to chastise him and expose him for his guilt. Two things happen at the end of the tragedy. Hamlet kills the king alongside four other victims. The audience gets surprised since they did not expect that to happen. Reasons behind the killing of the killing are so obvious such that the audience has forgotten the initial reason for revenge. People do not hear the death of Hamlets father in the end of the play. The king gets killed as a result of different reasons from vengeance. The tragedy, therefore, reaches its catastrophe. The kings death, however, is overshadowed by several immediate causes and several other deaths. These killings are different from other killings that had occurred, previously, in the tragedy. Most of the previous deaths happened but was not noticed. The queen also dies, and people do not seem to notice. We only see Hamlet biding him farewell (Shakespeare 58). Hamlets death also gets overshadowed and blurred. After his death, he is no longer remembered. The tragedy can be explained by two formulas. First, we shall use the formula of the story where Hamlet avenges his fathers death by killing the king. According to tthe formula of the plot, Hamlet does not kill the king for that reason but for different reasons other than vengeance. This contradiction is part of the play by Shakespeare who intended to express himself by teasing the audiences emotions. The tragedy fulfills its task set from the beginning, but it keeps on deviating. The audience realizes later that it came from a very different direction. The reasons that prevented Hamlet from killing the king, led to the death of the king. The catastrophe gets to a point of contradiction when the play is interrupted by irrational events. However, the mystery and obscurity come from the author. Conclusion In conclusion, the plays contradiction revolves around the story, plot, and the dramatis. These three factors develop differently. Hamlet makes feelings of the audience move to two levels. First, one can see the goal of the tragedy and secondly the digressions arise. After the kings death, the death of Hamlet, the protagonist, attracts people immediately. This gives the spectator understand the contradictions and conflicts that existed throughout the play. Different people give different reasons for Hamlets delay or failure to act. Some say that the task given to him was tough for him to tackle. Others believe that that Hamlet was a coward with some other critics arguing that Hamlet was an imaginary person since he had long died even before the start of the play. However, we have found out that it was the authors tactic to bring out the message intended to give his audience. He, however, manages to kill the King at the end of the play, though he appears to have killed him for differe nt reasons rather than vengeance for his fathers death.

Legal Advice for Harry and Mrs.Tourniquet in Relation to the Accident Essay

Legal Advice for Harry and Mrs.Tourniquet in Relation to the Accident that Led to Employment Dismissal - Essay Example This essay declares that the main point of substantiating the school’s governor’s dismissal is negligence. However, Mrs. Tourniquet may also argue that the school had also become negligent since they had not made sure that a nurse would be available during school hours. There was negligence on the side of the school management because they were unable to make sure that pupils be given proper medical attention, when accidents occur. If Mrs. Tourniquet will use this as a defense, it does not mean that she will not be held liable, but at least the parents of the child may sue the school, and not only Mrs.Tourniquet to demand damages. Certainly, Harry or his parents may demand damages first from the school because it was their obligation to look after their child. If only there was a nurse during the time of the accident, Harry’s leg may have not been amputated, and Mrs. Tourniquet will not be provoked to do anything that is beyond her responsibility as a biology tea cher. This paper makes a conclusion that dismissing Mrs. Tourniquet does not exempt the school from the obligation of providing monetary compensation. The dismissal may not be justified by Mrs. Tourniquet’s wrongdoings, but it is a learning experience for education institutions in not ignoring the possibility of accidents taking place at any point, and at any day. To conclude, Harry may demand damages from the school. Mrs. Tourniquet is still likely to be dismissed for her negligence and misconduct.
