Objectives:  The Airline Reservation System to be used at different reservation agency to reserve to seats for passengers online. It is a customer oriented software and also easy to use. The Reservation System is an attempt to integrate the services offered by the different airlines and companies across the world.

STEP-1 CONTEXT DIAGRAM OF THE PROBLEM, ALSO KNOWN AS DFD-0

As the inherited feature of the function oriented design, we worked on the top-down-approach. According to this approach the main module ( context diagram of this software) Is further decomposed into several lower level modules that perform distinct functions. As a user (our client) can express his query in several forms like •

• •

He wants to know about the reservation position i.e. confirmed or not confirmed (submodule1) He is interested in the details of any flight of any airline (submodule-2) He requests to reserve a seat in any of the flight of any airlines (submodule-3)

 Thus further we can divide our DFD into three DFDs on the basis of the functions required by the user. The main functions and corresponding DFDs are
