목차

1.Chapter Ten Minicase

2.Chapter Eleven Problems and Exercises

3. Draw a class diagram model to depict relationships between the objects you identified in problem 2. Be sure to specify the multiplicity. Were you able to identify any aggregate relationships

3. Chapter Eleven Minicase
1. Schedule an interview with the business analyst responsible for your school's registration system. Based on the information the analyst provides, perform the following:
a. Draw a context model diagram
b. Identify the actors and the use cases they initiate
c. Complete a use-case description for the event of a student enrolling for a course. Do the same for a student dropping a course
d. Using the use cases you gave previously prepared, construct activity diagrams and then a class diagram

4. Chapter Twelve Problems and Exercises
1. How can a successful and thorough systems analysis be ruined by a poor systems design? Answer the question relative to these factors:
a. The impact on the subsequent implementation (in other words, the systems implementation phases, which you studied in Chapter 3
b. The lifetime of the system after it is placed into operation
c. The impact on future projects

6. A programming assignment in the classroom is a subset of a systems design. Obtain a copy of a programming assignment from a current course. Evaluate the design from the perspective of the system design phase tasks and the completeness of the design specifications

본문내용

1.[ Chapter Ten Minicase ]
1. A new production scheduling information system for XYZ Corporation could be developed at a cost of $125,000. The estimated net operating costs and estimated net benefits over five years of operation would be :

Assuming a 12 percent discount rate, what would be the payback period for this investment? Would this be a good or bad investment? Why? What is the annual ROI (return on investment) for the project? What is the net present value of the investment if the current discount rate is 12 percent?

☞ 위의 그림은 Net Present Value 분석과 Payback 분석을 한 표이며, 이것을 통해서 시스템에 투자에 대한 손익을 한눈에 파악을 할 수 있을 것입니다. 즉, Payback 분석을 통하여 Payback period가 대략 4.5 year로 나온 것을 표와 그림을 통해서 알 수 있을 것입니다.
☞ 손익을 계산해보면, $8,147만큼의 이익을 낼 수 있으므로 좋은 투자로 볼 수 있을 것입니다.
