Sample Paper : Movie Rental Business

The aim of this project is to implement database design steps in a Movie Rental business, with the purpose of storing relevant data about the customers and the movies they have rented. The business has a system, represented in Table 1, that “In its current form, the table is a traditional database. Should you keep it that way?” The answer to this question triggers the project and yes, it should be kept that way. Traditional databases, also known as relational databases, organize the data into tables, which can be related based on common data (Halpin, 2001), enabling a better understanding of the relationships among the entities. Relational databases have several advantages like the process of normalisation, less redundancy, the use of SQL and DDL, more flexibility when changing or adding data, being transactional which makes it easier to backup.

 

The project advances with the process of implementing the database, followed by the justification of the database design steps.

Normalize Data

Here first we have normalize the above table and create separate tables. The initial table was in 1NF. In order to be in 2NF redundant data was moved to a separate table, remaining the information shown above in Table 2, which was already in 3NF since every field depended on the primary key.

Considering the remaining data, it was clear that it would be easier to group the data in tables where the fields were dependent on the primary key, creating Tables 3 and 4. They were already in 3NF, achieving all the requirements for 1NF and 2NF

image.png

Almost all of the data was separated in tables, only “quantity” was missing, so the best way to incorporate that data and connect it to the rest of the database was to make a relationship with the Rental Table and the Film Table, with 2 Foreign Keys creating a Composite Primary Key.
