I need help making a UML Class Diagram: I have created on below.

Question:

The ABC company keeps track of a companys employees, departments, and projects. Suppose that after the requirements collection and analysis phase, you are provided the following description.

• The company is organized into departments. Each department has a unique name, a unique number, and a particular employee who manages the department. We keep track of the start date when that employee began managing the department.

• A department may have several locations. A department controls a number of projects, each of which has a unique name, a unique number, and a single location.

• We store each employees name, SSN, address, salary, gender and birth date. 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. We also keep track of the direct supervisor of each employee.

• We want to keep track of the dependents of each employee for insurance purposes. We keep each dependents first name, gender, birth date, and relationship to the employee.

  Design UML class diagram for the ABC company. Specify relationships between classes.
