Exercise 1 (Individual Assignment) [25 points] Several objects classes shown below have attributes that are really pointers to other object classes and which could be replaced with associations. An employer 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. Car owner ID is the ID of the person, company, or bank who owns the car. A Car loan may be involved in the purchase of a car. Burying object references as pointers is the incorrect way to construct an object model. Prepare an object class diagram in which the pointers are replaced with relationships. Try to get multiplicities right. You may need to add one or more object classes of your own. Eliminate all IDs. You must use a professional diagramming tool, such as Visio, to draw the class diagram.
