A database named yourusernameFMA has been set up for you to use for this assignment. For the FMA you must create the required tables and run the queries using this database. If you are unable to access this database by the last session of the module, please inform your tutor so that the problem can be resolved.
Note: you should not make changes to your FMA database once you have submitted your work. Marks will be lost if the queries you submit cannot be run on the FMA database that you have created.
Review the feedback from your TMA to ensure that your database model and table specifications are correct. Make any amendments necessary before creating the tables. Write and run CREATE TABLE statements for each table. Each statement should include a brief comment at the start stating its purpose, the name of the author and date of creation. Statements should be clearly set out with each column definition starting on a new line and using UPPERCASE for MySQL reserved words. They should include primary and foreign keydefinitions as appropriate and define the database engine to be used.
Hint: Think about the order that you need to create the tables in.
