Exercise: UML Domain Model Class Diagram

Read the case and the use case diagram below, and then draw a UML domain model class diagram of the AVS system. state any assumptions you make:

Your client's organization is called A Video Store(AVS), a company that runs a series of discount video rental stores. The processes in their stores are as follows. Before a video can be put on the shelf it must be cataloged and entered into the video database. Every customer must have a valid AVS customer card in order to rent a video. Customers rent videos for seven days at a time. Every time a customer rents a video, the system must ensure that they do not have any overdue videos. If so, the overdue videos must be returned and an overdue fee paid before the customer can rent more videos. Likewise, if the customer has returned overdue videos but has not paid the overdue fee, the fee must be paid before new videos can be rented. Whenever any payment is received, the system should print a receipt. Every morning, the store manager generates a report that lists overdue videos. If a video is seven or more days overdue, the manager calls the customer to remind them to return the video. If a video is returned in damaged condition, the manager removes it from the video database and may sometimes charge the customer.
