(b) Each department in part (a) employs one or more employees, and each employee works for one department. (c) Each of the employees in part (b) may or may not have one or more dependants, and each dependant belongs to one employee. (d) Each employee in part (c) may or may not have an employment history. (e) Represent all the ER diagrams described in (a), (b), (c), and (d) as a single ER diagram.
