Hi Please help.
Map the E-R diagram to a relational schema. (Show the ERD for the database. )
The company is organized into departments. Each department has a name, a number, and an employee who manages the department. We keep track of the start date when that employee started managing the department. A department may have several locations. We store each employees name, social security, address, salary, sex, and birth date. Employees are classified into managers, technicians, engineers, or secretaries based on their functions. An employee is assigned to one department, but may work on several projects, which are not necessarily controlled by the same department. We keep track of the number of hours per week that an employee works on each project. Each project is located in a specific city. We also keep track of the direct supervisor of each employee. We want to keep track of the dependents of each employee for benefits purposes. We keep dependents name, sex, birth, date, and relationship to the employee.
