A small airline has just purchased a computer for its new automated reservations system
OBJECTIVE:
The objective of the assignment is to use object-oriented design techniques to design an application.
DESCRIPTION:
A small airline has just purchased a computer for its new automated reservations system. You have been hired to design an airline seating application for the FBN (Fly-By-Night) Airlines. In this portion of the assignment, the task is to do the object oriented design for the application. This system will be used only by the company and its employees. Customers will not interact with the system.
Your application should, of course never assign a seat that has already been assigned. When the first class section is full you should ask the user if s(he) would like the economy section and when the economy section is full you should ask the user if s(he) would like the first class section.
REQUIREMENTS:
Design an application that assigns seats on an airplane. The airplane has 20 seats in first class (five rows of 4 seats each, separated by an aisle) and 90 seats in economy class ( 15 rows of 6 seats each, separated by an aisle). Your app should take four commands: add passengers, show seating, create ticket and quit. When passengers are added, ask for the passenger's name, the class (first or economy), the number of passengers traveling together ( 1 to 2 in first class, 1 to 3 in economy), and the seating preferences (aisle or window in first class, center or window in economy). Try to find a match and assign seats. Then create tickets for the passenger. The passenger tickets should be stored in an output file so they can be retrieved and printed at the airport. If no match exists, display a message. Follow the design process that is described in the presentation for this topic.
Once you have a conceptual model for your application, you should identify the classes you will need to implement your model. Once the classes have been identified you need to identify their responsibilities and relationships to the other classes
1. A UML class diagram showing all your classes and the relationships between them.
2. A sequence diagram of one particular interaction between objects in your application. Label the diagram with the name of the scenario you are modeling.
