...Database Final Exam review 1. What is data? Data are values of qualitative or quantitative variables, belonging to a set of items 2. What is information? Data becomes information after it has been processed to add context, relevance and purpose. 3. Role of data and information – Data and information allow users to make better decisions based on good information and data 4. Field – a column in a table which is a property of an entity (attribute) 5. Record – A row or tuple in a table 6. Tuple – A record or row in a table 7. ACID - ACID stands for Atomicity, Consistency, Isolation, and Durability. Atomicity means if one part of the transaction fails, all of the transaction fails, leaving the database unchanged. Consistency means the data written must be valid according to all the rules and the rules are applied from state to state. Isolation means that the data used during the execution of a transaction cannot be used by a second transaction until the first one is completed. It is executed as if it were being executed serially. Durability ensures that once transaction changes are done, they are permanent and cannot be undone or lost, even in the event of a system failure. 8. What is data redundancy and which characteristics of the file system can lead to it? Data redundancy exists when unnecessarily duplicated data are found in the database. It is the result of poorly designed databases which allow the data to be stored in different locations...

...I used to play soccer for a club,just for recreational purposes,in fact i was one of the cofounders of the team. The team we assembled was a mixture of young and old, and for this reason we were the laughing stock of the league, because all other teams were made up solely of young players, who were exceptionally talented. The team ended up on the wrong side of the score for the first few games we played, and got nicknamed the “whopping boys”. Eventually we grew tired of the nickname and of our performances on the field, and we decided to try and improve things, first thing we did was to elect a leader for the club. Even though i didnʼt want the job, i was voted into the position, and as the president it was my duty to represent my team when the league called for club meetings. At the time we were all students, so it was decided that we would all contribute towards any and all expenses,but unfortunately when you dealing with a blend of young and old, things donʼt always go according to plan, people constantly made up excuses for not showing up for practice, or for not contributing towards our equipment. Even though it wasnʼt my duty, i took it upon myself to ensure that every single player showed up for practice, i used to drive up to the houses of all those who didnʼt have any transportation. It was a tiring job, but i realized that if i wanted the team to be successful, i had to make certain sacrifices, some of which included taking money out of my own pocket...

...patient for hearing aid suitability. It was agreed that these three sessions encompassed all aspects in Audiology she may come across in her future career. For example, she can fit a hearing aid, she can assess a patient and she has learnt that not all fittings are straight forward, for those presenting with a unique problem(s). The end product is patient satisfaction, provide a solution for the patient and to support that in practise. Leanne has come on in leaps and bounds since her early days in the department. She is confident, but finds it difficult to ask questions. However, she does manage talk about things in the appointment through her reflective reporting. This is something I may need to talk with her about when I have the final meeting with her. But I am not overly concerned at this moment in time. The 3 reflective reports that Leanne produces is of good quality, informative and reasonably accurate. It also highlights aspects of training she mentions that we both have undertaken together in the appointment, so I suppose she is reporting her own training and that of mine in her words, that I can use as evidence that can be signed off. Each three reflective reports enclosed have been signed by myself and my mentor-supervisor, including this document.

...the students are Bill and John. Bill believes that the completed -contract method is most like recognizing revenue at point of delivery because in the end the final product is delivered and has fulfilled any requirements to recognize revenue. John believes that percentage-of-completion is most like point of delivery and this allows a company to recognize revenue over time. I support Bill’s opinion that the completed-contract method is closest to recognizing revenue at point of delivery. The reason I support this is because while there is still construction taking place, as in the percentage-of-completion method, there still is no actual product being delivered. Along with no product being delivered, it is possible that the final product may never actually be made. If there’s a chance the end product not being made then there is no way to recognize revenue for that product. Using the completed contract method we hold off on recognizing any revenue until the final product is finished and delivered to the client. In my opinion completed contract fulfills the requirements of revenue recognition which are (1) the amount has to be realized / realizable and (2) the revenue must be earned. In completed contract at point of delivery the item can be considered earned now that it is completed and ownership has passed to the final customer. Percentage-of-completion does help serve large contracts that take years to complete so that a company can recognize some revenue every year. The problem...

...Utter chaos or sheer comical genius? The Eric Andre Show transcends what most people typically think of in terms of a variety show. This man has taken his talents as a comedian and created something that is truly unforgettable. The show on Wednesday, September 19 started with Eric Andre running out on stage throwing beer, sandwiches, what seemed to be chicken carcasses, and many other objects out into the crowd as he jumped off stage and began to run through the dense mass of people pushing, shoving, and simply making a riot amongst the observers. He disappeared and shortly after appeared back on stage fully naked running around the set. Things slowly settled down and it was time for his first guest, Russell Brandt. The crowd grew eager and when he finally came on stage, it was clear that it was in fact not he. Either that, or Russell Brandt changed his image to that of a malnourished Philadelphian homeless person. Once on stage “Brandt” sang a song, in what seemed to be English accompanied by a plastic guitar and a 2 liter bottle filled with some unknown foamy liquid that eventually also ended up in the crowd. His next two guests consisted of a local juggler and Freeway, who is a native rapper of North Philadelphia. It was clear that neither of the two were aware of what they were actually participating in. Right as the juggler was about to begin his performance, the lights dimmed and Doc Chicken emerged. This was nothing more than a rubber chicken with a stethoscope...

...One of the strategies we discussed to resolve the conflict was (1) Meet with the three employees to discuss their ideas, (2) Meet with Jan and Marc to understand why they are unable to come to an agreement or compromise, (3) As the manager direct each employee to develop and present their ideas about the ad to a management team. The first strategy we discussed was to have a meeting with Jan, Sally, and Marc to find out why and how we could help them come to a decision about the ad. Allow each employee to present what ideas they have for the ad. As the manager listen to the idea, explain to them your views on what makes a successful ad, and make any suggestions for improvement on the ideas, if needed. Feedback is welcome, but we have a deadline to meet. Ask each one of them what they can produce to help promote this ad. Also remind them that they have been successful in the past and we are sure you can work together to solve this conflict. It’s about compromising. The second strategy is meeting with Jan and Marc, since they were unable to compromise. Even though they worked very well together in the past and Sally tried to get them to come to an agreement they could not set their personal values aside. The manager needs to be the negotiator to guide employees to see others views. Compromise is the key to good negotiation. You need to be able to give in a little to get closer to what you want. Have Marc and Jan present their ideas for the ad, give feedback on...
