the Project Manager of UAAR-LMS systems for PMAS-AARU, you are given the task to develop a new student registration system. The university would like a new client-server system to replace its much older system developed around mainframe technology. The new system will allow students to register for courses and view report cards from personal computers attached to the campus LAN as well as over the Internet. Professors will be able to access the system to sign up to teach courses as well as record grades. Due to decrease in HEC funding, the university cannot afford to replace its entire system at once. The UAAR will keep the existing course catalog database where all course information is maintained. This database is an Ingres relational database running on an Oracle platform. Fortunately, the UAAR has invested in an open SQL interface that allows access to this database from UAAR’s Unix servers. The legacy system’s performance is rather poor, so the new system must ensure that access to the data on the legacy system occurs in a timely manner. The new system will access course information from the legacy database but will not update it. The registrar’s office will continue to maintain course information through another system. At the beginning of each semester, students may request a course catalogue containing a list of course offerings for the semester. Information about each course, such as professor, department, and prerequisites, are part of the project. The new system will allow students to select four course offerings for the coming semester. If a student is not assigned to its primary choices, he will indicate two alternative choices for courses. A Course offering should add at least three and at most ten students. The one with fewer than three students will be canceled. Students are given the choice to change time period for the course. Students must be able to access the system during this time to add or drop courses. Once the registration process is completed for a student, the registration system sends information to the billing system so the student can pay for the semester. If a course fills up during the actual registration process, the student must be notified of the change before submitting the schedule for processing. At the end of the semester, the students can view electronic report card. Since student grades are sensitive information, the system must employ extra Security measures to prevent unauthorized access. Professors must be able to access on-line system to indicate which courses they will be teaching. They will also need to see which students signed up for their course offerings. In addition, the professors will be able to record the grades for the students in each class. Design a detailed Domain model for the UAAR student registration System.
