1. Question 3.25 in textbook page 57. Several classes shown in Figure E3.12 have attributes that are really references to other classes and could be replaced with associations. A person may have up to three companies as employers. Each person has an ID. A car is assigned an ID. Cars may be owned by persons, companies, or banks. Owner ID refers to the ID of the person, company, or bank who owns the car. A car loan may be involved in the purchase of a car.

Prepare a class diagram without IDs and using association and generalization. Try to assign multiplicities. You may need to add one or more classes of your own. Note: 1. Must use correct UML notation. 2. Must typed in word file
