A company has a number of employees. The attributes of Employee include employeeID (primary key), name, address, and birth date. The company also has several projects. Attributes of Project include projectName and startDate. Each employee may be assigned to one or more projects, or may not be assigned to a project. A project must have at least one employee assigned, and it may have any number of employees assigned. An employee's billing rate may vary by project, and the company wishes to record the applicable billing rate for each employee when assigned to a particular project. At the end of each month, the company mails a check to each employee who has worked on a project during that month. The check amount is based on the billing rate and the hours logged for each project assigned to the employee.Draw class diagram
