PurpleBox is a database system which keeps track of the information about Movie Rentals $($Blu$-$ray

DVD$,$ digital, and other formats$)$ as well as customers. It will be used exclusively in a single movie

rental shop on Weber$$s main campus. Without the use of this database system the rental shop

would have to maintain scattered inventory records and customer information. Designing a

centralized database will help to provide general accessibility to this information as well as ensure

the data are preserved more securely$.$

The Business Logic

The rental shop has customers who can physically rent $($many different formats such as Blu$-$Ray,

DVD$,$ and more$)$ or digitally stream Movies $($hereby referred to as Movie Rental Items$)$ directly from

their shop $($we are not dealing with multiple locations$)$
