Information Systems Chapter Questions
Information Systems Questions. A couple of paragraphs per question, please.
* Consider a system that produces budget reports for your department at work. Alternatively, consider a registration system that produces enrollment reports for a department at a university. For whichever system you choose, answer the following design questions: Who will use the output? What is the purpose of the output? When is the output needed, and when is the information that will be used within the output available? Where does the output need to be delivered? How many people need to view the output?
* Under what circumstances would you recommend that a file server approach, as opposed to a client/server approach, be used for a distributed information system application? What warnings would you give the prospective user of this file server approach? What factors would have to change for you to recommend the move to a client/server approach?
* The Internet is a network of networks. Using the terminology in this chapter, what type of distributed network architecture is used on the Internet?
* One of the potential problems with gathering information requirements by observing potential system users is that people may change their behavior when they are being observed. What could you do to overcome this potential confounding factor in accurately determining information requirements?
*Choose a transaction that you are likely to encounter, perhaps ordering a cap and gown for graduation, and develop a high-level DFD or a context diagram. Decompose this to a level-0 diagram.
*Before a new system is implemented, it should go through various stages of testing to ensure the system performs and behaves as designed. What are the various types of testing that should occur for a new
system? Which do you believe is most important and which do you believe is most difficult to perform?
