The library system needs to modernize its existing system. The library materials are currently cataloged in a database, but media checkout is currently done by hand.

Within the system, library patrons should have the following abilities:

• Sign up for a new library membership

• Check out media using their membership card or number

• Reserve media using their membership card or number

• Reserve available meeting rooms

• View their transaction history

• View outstanding media that has been checked out

• View outstanding media that has been reserved

• View current fines on their account

• Pay any fine balance

Additionally, library staffers should have the ability to do the following:

• View library member's information (including fines, reservations, meeting rooms, and checked-out materials)

• View the checkout/reservation history of any item in the media catalog

• Approve meeting room reservation requests

• Accept payments for member fines

• Add and Edit materials in the catalog
