Construct an ERD to represent employees and positions. For employees, the ERD should record the unique employee number, first name, last name, department name, office number, hire date, and date of birth. For position, the ERD should record the unique position number, position name, and step number. Positions can be classified as management, associate, or other. Management positions have a salary range (minimum and maximum) and a car allowance amount. Associate positions have an hourly rate range. There are no attributes to record for other position types. An employee must hold one position. A position can be held by many employees.
