System analysis and design

Long Answer Questions

A university has an online registration system that enables the staff of each academic department to examine the courses offered by their department, add and remove courses, and change the information about them (e.g., the maximum number of students permitted). It should permit students to examine currently available courses, add and drop courses to and from their schedules, and examine the courses for which they are enrolled. Department staff should be able to print a variety of reports about the courses and the students enrolled in them. The system should ensure that no student takes too many courses and that students who have any unpaid fees are not permitted to register. (Assume that a fees data store is maintained by the universitys financial office, which the registration system accesses but does not change).

1) Draw a level-0 data flow diagram (DFD) for the university registration system.

2) Draw an Interface Structure Diagram (ISD) for the university registration system.

3) Based on the data flow diagram created in section 1, create a structure chart for the system.

4) Develop a use scenario for the university registration system.
