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 catalogued 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.
