For my Databases module i was tasked with creating a database, adding data, creating selections and performing a transaction.
Used to create the tables which i use for my project.
Was used for an earlier version of the product where i created a function to perform input validation.
Used to add data to the tables which will be used by the selections.
Select data from the tables using different types of joins, subqueries and set methods.
Mimic a transaction to modify an entry in the table and add a new value.
