Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy (EER) if appropriate.

Two-Bit Drilling Company keeps information on employees and their insurance dependents. Each employee has an employee number, name, date of hire, and title. If an employee is a full-time inspector, then the date of certification, the renewal date for that certification, and the yearly salary should also be recorded in the system. If an employee is a part-time inspector, then the date of certification, the renewal date for that certification, and the hourly wage should also be recorded in the system. For all employees, the Social Security number and dependent names should be kept. All dependents must be associated with one and only one employee. Some employees will not have dependents, while others will have many dependents.
