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. 1.1) Draw an Extended Entity Relationship Diagram (EERD) using the information provided above. Include all attributes and their datatypes.
