A RENTAL BUSINESS $-$ DESIGN

You have been asked to create an information system for a rental business $($SuperRent$)$

using the following attributes and constraints:

SuperRent only rents out DVDs for a fixed duration, i$.$e$.$ all transactions are

rentals.

DVDs content can be: movie, game, or music.

DVDs can be of the following types: new arrival, promotional, normal.

Each DVD is identified by a unique stock number.

Rental charges vary according to the DVD content.

Rental duration varies according to the DVD type.

A Late fee is charged per day when a DVD is returned after the due date.

The late fee rate varies according to the DVD content.

Only cash payments are accepted.

Only members can borrow from SuperRent; members are identified by a unique

membership number.

Members can rent items from any store and return them to any store.

A rental cannot be completed before paying the late fees.

On completion of rental transaction, the customer receives a printed receipt. The following is the Rent DVD use case in expanded, essential, conversational style. It includes both a typical course of events, and an alternatives section.

Based on the Process Rental use case and using the provided class diagram:

Assignment $2$:

Add the necessary attributes based on the provided list of attributes and constraints

$($see first page$).$

Find the control classes and add the operations. The output of this activity is the class

diagram representing the entity classes and control classes by assigning necessary

operations.

Assignment $3$:

Draw the sequence diagram of the Use Case Process Rental.

Provide the Java code $($classes and their implementation$)$ based on the modified class

diagram.

The grade will depend on the use of object$-$oriented design principles

not only on the working solution.
