Question

Imagine you have been asked to develop a booking system for the Colombo Marriot
Hotel, a new hotel proposed to be built in the Colombo Port City. Your specific task
is to design the “make advance reservation” scenario. When making an advance
booking, the scenario of events is as follows.
To book a room, the customer requests to view room types and is provided three
types of room: Single, Double or Family. The customer then selects a room type and
is then supplied with details of each room type, including En-suite bathroom, minibar, internet connection and/or TV, etc. The customer then needs to enter the start date
and number of nights of stay. If a room is available, the system displays the cost of
the stay. If the customer is happy with the cost, the customer enters a name and email
address. The system will then make the reservation and provides a reservation
number. The customer is then asked to supply payment card details, including card
number, issue date, and expiry date. The system will then transact the payment and
provides confirmation of reservation.
An existing payment transaction system is already in place at the Heritance. There is
no requirement to replace the existing payment transaction system which works
perfectly well at the moment. The new hotel reservation is required therefore to
integrate with the existing payment transaction system.

1. Draw use-case diagrams for the make advance reservation scenario.
2. Draw a class diagram for the Hotel Room Booking System. You may assume
that an external system exists for payment card validation.
