2SYSTEM ANALYSIS AND DESIGN
1. Introduction
The following report states the system analysis of Air Australia by stating the details of
the business operations that are included in the system. A detailed analysis of working schedule
for developing the information system is detailed in this report. The completion of the
information system should be done according to the schedule done. This report also states the
design of the system as use case diagrams, data flow diagram, entity relationship diagram and
with interfaces that will be used in developing the system.
2. Developing the Information System:
Air Australia is reservation system that maintain the database of the airlines in Australia,
the passengers as well as the reservations that are done by the passengers. The information
