Consider the following set of steps for booking a table at a restaurant―“Record booking” use case (Priestly, 2003, p. 63):
Record booking 1. The receptionist performs the “Display bookings” use case. 2. The receptionist enters the customer name and phone number, the time of the booking, the number of people at the table and the table number 3. The system records and displays the new booking.
The following functionality has been designed so far for this restaurant booking system:
where the “Display booking” use case simply retrieves the bookings of a given date entered by the receptionist.
Write a use case description for editing a booking. Think about what aspects of the booking can be edited. However, do not allow for changing the date of the booking (your description does not include changing the booking date). Include the following fields in your answer: use case name, participating actors, flow of events, entry conditions and exit conditions.
(b)               4 marks Based upon the use case you wrote in a), write a use case description for the exceptional case of the table selected being too small for the number of people who will attend during the booking. If the table does not provide enough seats, the table is not large enough for eating the meal.
In your answer, write only the flow of events (i.e., the steps of the flow of events).
