As the head of information systems for a college you are tasked with developing a new student
registration system. The college 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. Professors will be able to
access the system to sign up to teach courses as well as record grades.
Due to a decrease in federal funding, the college cannot afford to replace the entire system at once. The
college will keep the existing course catalog database where all course information is maintained. This
database is an Ingres relational database running on a DEC VAX. Fortunately the college has invested in
an open SQL interface that allows access to this database from college’s Unix servers. The legacy system
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
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, will be included to help students make informed decisions.
The new system will allow students to select four course offerings for the coming semester. In addition,
each student will indicate two alternative choices in case the student cannot be assigned to a primary
selection. Course offerings will have a maximum of ten students and a minimum of three students. A
course offering with fewer than three students will be canceled. For each semester, there is a period of
time that students can change their schedule. 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 be billed 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 student will be able to access the system to view an 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 the 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.
Give below are the UML Use Case Diagram and Use Case Specifications (Descriptions). Your task is to
draw the Sequence and Class Diagram(s).
