Answer the given problem:

problem 1: Draw an entity relationship diagram (or ERD) for the given situation:

A company has a number of employees. Each employee is identified by an Employee_Id. The company wants to store Employee_Name, Employee_Address, and Employee_BirthDate in the database. The company as well has some projects. Each project is recognized by a Project_Id.  The company wants to store Project_Name and Project_StartDate in the database. Each employee should be assigned to one or more projects, or might not be assigned to a project. A project should have at least one employee assigned and might have any number of employees assigned.  An employee’s billing rate may differ by project, and the company wishes to record the applicable billing rate (Billing_Rate) for each employee when assigned to a specific project.

Please use Visible Analyst to draw the ERD. Copy and paste the diagram in the Word.
