22. Case Study State Machine Diagram Higher Education University Management System
You are an analyst given responsibility of preparing state chart diagram for Student Life
Cycle of a Higher Education University Management System being developed. While you
interact with the Registrar of the University, who is your client you receive the following
information
• The University will maintain a prospect database. Prospects will be those individuals who
submit the purchased application to University. After Submission the prospect may or
may not join the program
• If the prospect does not register the program within three months he is not pursued
further for admission.
• A prospect may register for the program. Those who register are called as Registered
Students. Registered Students appear in the exam and can fail or pass. Registered
students who fail have to reappear to pass the program. If he does not pass the exam
within stipulated time period his registration is cancelled.
• A registered student’s registration can be cancelled for ineligibility or gross indiscipline.
• A registered student can abandon the program midway. Those who abandon the
program can reregister within a stipulated time period else their registration is cancelled.
You are required to prepare a state chart diagram for the above case.
