![FeastFam is a restaurant group which consists of multiple restaurants nationwide. Due to recent
restrictions imposed by the government, the group has had to adapt to a new way of managing
information in their daily operations. FeastFam has approached you to help them with the
creation of a database which will keep track of the following information:
• FeastFam franchise group has a main headquarter office. The address of this office should be
stored in the database.
• FeastFam has many restaurants across South Africa (indicated using a “has-a" relationship).
• Each restaurant has a name, location and phone number.
To handle reservations the following needs to be considered:
• Each restaurant can have many customers make reservations.
• Each customer can have many restaurants at which they make reservations.
• Each customer has a name, surname and contact number.
• For each reservation the following information is stored: Date, time, number of guests.
When the customer arrives with their guests, data such as their temperature must be captured in
a ReservationLog.
• Every reservation, therefore, has multiple ReservationLogs.
• The data that must be stored for each guest on arrival includes: Name, surname, contact
number and temperature.
The FeastFam database, furthermore, needs to keep track of two types of staff members,
namely, administrators and waiters. Staff members must be either an administrator or a waiter
but not both.
• Each staff member has a unique staff ID, name and surname.
• Each administrator has the name of their highest qualification stored in the database.
• Each waiter has a date when they started serving.
• Each waiter is also assigned many reservations and each reservation is handled by a single
waiter.
