Video Reservation Database System
A local video rental service has contacted you to develop a database to electronically facilitate a
streamlined reservation and rental process. The database assist in managing member, title, copy of title,
and rental information to provide users with an efficient and enjoyable video rental and reservation
experience. The database will store detailed member information, including attributes such as identity (a
unique identifier for each member), last name, first name, address, city, phone number, and join date,
which records when a member became part of the platform. Each member can reserve multiple titles
associated with their identity. At the same time, each title can be reserved by many members, allowing
for multiple users to access the same content. The title keeps the catalog of video titles available in the
reservation system including identity for each title, title name, description, rating, category, and release
date. These attributes help users browse and select right titles for reservation.
A copy of title representing instances of a title and comprising of a unique identifier for each copy and
status (indicating whether the copy is available for reservation or not) is being kept. Each title can have
many copies associated with it and thus, ensuring that multiple physical copies of the same title are
available for members to reserve.
A rental records transaction when members rent titles. Each rental transaction is associated with a
specific copy of a title, ensuring that only one member can rent a particular copy at a time. Specific
information such as book date (when the rental was initiated), account rental date (when the rental was
added to the member's account), and expiry rental date (when the rental period expires) are kept for the
rental transaction. Each rental transaction is associated with a specific member, indicating the user who rental transaction. Each rental transaction is associated with a specific member, indicating the user who
rented the copy. The complete Entity Relationship Diagram (ERD) for the proposed database model
comprising of all entities involved and their respective attributes are presented in the Figure 1 as shown
