To store information about gym classes, a relational database was created using MySQL. There are
four tables in the database: User, Class, Timeslot, and Booking. A user takes one or more classes.
A user could be a student (Y') or not ('N’'). A class may be available in different times. The
instructor's name and start_time are stored in the Timeslot table. In the Booking table are recorded
the user's class reservations (value 1 reserved, 0 free).
The database's Entity-Relationship model is shown below:
