Q1) Airline Project: Problem Description The aim of this project is to build an airline reservation system. The system should provide two basic sets of services to an airline: 1. The first set of services allows the airline to provision its system. For example, allowing planes to be added to the airlines fleet, classes of flight to be added, and flights to be scheduled. 2. The second set of services allows the airline to service customers. For example, allowing a passenger to query the flight schedule for flights that satisfy an arbitrary condition, and to book, confirm, or cancel tickets. There are three kinds of tickets: first class, economy, and coach. The different kinds of tickets vary in a couple of ways: cost and refundability. The cost of a particular fare varies in the following ways: Type of Ticket First Class Coach Economy Craig Larman, 1998 Percentage of Full Fare 100% 85% 70% 19 Airline Project: Problem Description (cont.) If a first class or coach ticket is canceled, there is always a full refund. However, economy tickets are only refunded if they are canceled at least two weeks before the flight. When a booked reservation is paid for, it is said to be confirmed. The seat associated with a reservation which is booked but not confirmed may be reallocated when seats become scarce, thus effectively canceling the reservation.
