In Chapter 4, you saw the creation of the Tiny College database design. That design reflected such business rules as “a professor may advise many students” and “a professor may chair one department.” Modify the design shown in Figure 4.36 to include these business rules: An employee could be staff or a professor or an administrator. A professor may also be an administrator. Staff employees have a work level classification, such a Level I and Level II. Only professors can chair a department. A department is chaired by only one professor. Only professors can serve as the dean of a college. Each of the university’s colleges is served by one dean. A professor can teach many classes. Administrators have a position title. Given that information, create the complete ERD containing all primary keys, foreign keys, and main attributes.

In Chapter 4, you saw the creation of the Tiny College database design. That design reflected such business rules as “a professor may advise many students” and “a professor may chair one department.” Modify the design shown in Figure 4.36 to include these business rules:

  • An employee could be staff or a professor or an administrator.
  • A professor may also be an administrator.
  • Staff employees have a work level classification, such a Level I and Level II.

  • Only professors can serve as the dean of a college. Each of the university’s colleges is served by one dean.
