Introduction:
We live in the world of uncertainty. Everything is changing. The rule and
regulations, governmental policies, business relations, trade law technological
environment, social and cultural environments etc are changing in the continuous
flow. From the viewpoint of technology, information is the most important weapon
for financial institutions, economical sector, business organization etc to penetrate the
market and beat the competition. In other word, many organizations, financial
institutions, business sector all depend on their data/information for its regular
activities. So, it must be kept safe and secure so that authorised personnel can only
access it. A database with database management system is the backbone of an
efficient information system. Initially the first computer focused on the clerical tasks
(Leon, 1999) so that the file based management was popular but modern database
approach is popular because of the growing programming skills and complex
computer. Nowadays, different database management system is used by different
organization depending on their nature.
Airline reservation database system is the database management system for the
airline company and its different remote agencies. It performs different task such as
recording the traveller details, time schedules of the flight, total no of the seats, total
no of the reserved seats, payment etc (Ray, 2009). As a result, Airline reservation
system helps the user to retrieve the information from the database and update it
freely without any trouble. Likewise the main aims of this task is to designed the
airline reservation database system with the different function like storage
management, language interface, security management, recovery management,
concurrency control and transaction management etc.
When a traveller came to the outlets of Airline Company for the air tickets, he
first provides his full personal details. Those details were written in a customer form
with the date that the traveller wants. Then the computer checks the date and the
flight. The computers generate the unique ID (Seller, 2007) if the date has specific
flight. Again, the travellers have to provide their seat details like window side in
economy class, business class etc. Meanwhile, if the seat is empty then the system
reserved that seat. Finally the tickets is confirmed and generated after the payment.
However if the condition can apply traveller are free to cancel the flight.
These are the main business activities under airline reservation database system :
 This software application handle the transaction that takes place during air
ticketing such as blocking, reserving, rescheduling and also cancelling.
 The airline reservation system application helps Airline Company to maintain
the efficient scheduling of different flights, routes etc.
