Advising Management System (AMS) Case

In the School of Computer Science, Telecommunications, and Information Systems, all students are assigned to a faculty advisor upon matriculation. Faculty advisors are responsible for assisting students with schedule and course planning, career planning, and life. Faculty advising appointments are most often made by the front desk in the CTI main office. Because the School is growing so quickly, it has become necessary to develop a database that will:

  1. House faculty pre-set advising hours each quarter (e.g., MW, 2-4pm). These will change each quarter.
  2. Store students assigned to each faculty member
  3. Log appointments made for each student with the faculty member so that:
  1. Track student requests to change advisors (e.g., from Johnsonbough to Kalin)
  2. Track advisee load for each faculty member (e.g., # of students assigned to faculty)
  3. Track advising areas for each faculty member (e.g., CS, HCI, TDC, etc.)
  4. Trigger a request for the student file to be pulled and placed in the faculty mailbox 24 hours before the scheduled appointment when an appointment is made.
  5. Provide comment space for faculty to enter advising notes for each student.
  6. Trigger an e-mail note to the faculty with appointment information for each appointment that is created.
