Scenario Description 

 

 Zam Zam International Hotel is one of the famous hotels in Oman. It has several branches in Muscat and other parts of Oman. For the betterment of customer service hotel management decided to replace the existing reservation system by a new Web-based system. In the new system customers can register using e-mail and contact number. Customers can search for rooms that match their preferences by filling a form, in which they specify the following information: bed size, smoking or non-smoking preference, start and end dates of stay, and city where the hotel is located. After submitting the search request, the system checks the room availability and returns either a match and daily price or a non-match. In the case where a room is available, the customer can confirm the booking by providing his personal information (i.e., name, address, phone number, and email) and his  credit  card  information  (i.e.,  type,  number,  and  expiration  date)  for  billing  purposes.  After booking  the  room  and  storing  the  customer’s  information,  the  system  returns  a  confirmation number to the customer that the customer will use for check-in. A customer can cancel a reservation by simply specifying the reservation number. In this case, he/she must receive a cancellation notice. No particular restriction is put on the reservation cancellation. A system administrator manages the system. A consular and hotel staff assists the customers in the reservation and cancellation process if needed. In addition to that if a customer is not having credit card than he/she can make payment either by check or cash after reaching to the hotel. Therefore, we will need a mechanism to provide this flexibility and customization. Using an iterative development strategy, we are going to proceed through object-oriented analysis and design.
