Consider the following scenario to model. There are two types of people to model, faculty members and students. Faculty members and students all have common characteristics such as names and addresses. Faculty members also have ranks and tenure status, whereas students have majors and grade point averages. You can request any type of person to provide information about himself or herself. If you make this request of any person, you will get their name and address. If you make this request of a faculty member, you will also get information about tenure status and rank, whereas if you make this request of a student, he will tell you about his major and GPA. A faculty member may advise one or more students.
In addition to modeling the people, we should model courses. Each course has a name, and a description, and perhaps one or more prerequisite course. A faculty member may teach any number of courses. A student may take any number of courses.
Discuss how you would model this scenario in an object-oriented system. In particular, identify all classes, their attributes, messages, and operations. Identify the generalizations and inheritance relationships, as well as any associations. Also, indicate whether polymorphism is involved; and if so, where it is.
