A business consists of many departments where each department has a name, number, and an employee and a manager (who manages the department). The name of an employee is stored in such a way that we carn easily keep track of his/her first name, middle initial and last name. Track is kept of the date that the department manager started managing the department. Each department controls a number of projects where each project has a name, number and a location. We shall keep track of each employee's social security number, name, address, salary, sex, and birth date. We shall assume that each employee works for one department but may in fact work on several different projects. We shall keep track of the number of hours per week that an employee currently works on each project. Track will also be kept of the direct supervisor of each employee. Further, each employee may have a number of dependents. For each dependent, we store their name, sex, birth date, and relationship to the employee
