5. OO Modeling (40 Points total ) (40 Points total )
1) Write down all candidate objects and candidate actions in the following usage scenario (10 points)
《面向对象分析与设计》试卷第 5 页 共 7 页
This is a student registration system. There are full-time and part-time students. Each class has a set of scheduled times and a number of credit hours. When a user tries to register for a class, the system checks their schedule for time-conflicts. If there is a conflict, an error is returned. If there is no error, then the system checks to see if the total number of hours including this class is no more than the maximum number of hours for a full-time student. If so, then the system returns an error. If no problems are found, the system registers the student for the class, and informs the user of success.
2) Produce a class diagram to model the system. (Make sure to include all objects and actions that you will need for the sequence diagram you will produce in part 3 below.) (15 points )
3) Produce a sequence diagram to model the success-case of this scenario (i.e. the sequence of actions performed when there are no errors.) Please label everything with meaningful names, or include a description of each label. (15 points)
