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, instructor(s), timings, and classroom; (c) students, including student-id, name, and program; and (d) instructors, including identification number, name, department, and title. Further, the enrollment of students in courses and grades awarded to students in each course they are enrolled for must be appropriately modeled.

The assumptions made are: a. a class meets only at one particular place and time.

a.This ER diagram cannot model a class meeting at different places at different times.

b.There is no guarantee that the database does not have two classes meeting at the same place and time.
