A university registrars office maintains data about the following entities: (a) courses, including number, title, credits, syllabus, and prerequisites; (b) course offerings, including course number, year, semester, section number, instructors, timings, and classroom; (c) students, including student-id, name, and program; and (d) instructors, including identification number, name, department, and title.
