Description of the application:
The primary objective to develop this system is to provide the user more effective as
well as efficient air ticket booking experience via the utilization internet and mobile devices.
Followed by this aspect the approached air ticket booking application consist the abilities to
address all the user requirements. The approached ticket booking application is an online
application, which can be used by computers or by mobile devices through internet. In order
to initiate the working online ticket booking process, at first the user needs to enroll
themselves by providing all possible documents which includes the birth verification
document, identity proof as well as several other documents with the purpose to verify the
user validity. After completing the registration process the user will then login to proceed
further. Followed by the above step the user can then select the preferred airlines. After
selecting the airlines the user can then select the location from where s/he wants to travel and
then select the place to where s/he wants to go. After completion of this step the user will
then proceed by checking the seat availability of the selected plan and the user will then
chose the preferred seat. Followed by this step the user can easily book their air tickets and
the application will provide a detail view of the ticket which has been booked by the user.
Along with this since, the mobile number will be synced up with this application, the user
will get notifications in case of any update related to the booked ticket via massages.
Followed by the above aspects the approached application will provide the below
mentioned advantages:
 This system will help the users to book tickets via online which is cost effective as
well as less time consuming.
 It will provide a detail about the seat availability.
 It will offered a large variety of airline companies.

 It will effectively notify the user about any update.
Tiers of the system:
The approached application will consist three basic tiers which includes the
Presentation tier, Business logic tier and the data storage tier.
Presentation Tier-
This tier represents the client application or the user interface.
Business logic Tier-
The operations if the approached application is performed in this layer
Data Storage Tier-
This tier represents the database application in which the database operations are being
performed.
In order to develop the approached application the 3-tier concept has been selected
with the purpose to provide enhancement in the developed application. As it has been
identified from the application of 2-tier concept that since, it only consist of 2 layer this one
layer is depending upon another. However, in case of 3-tier application if any error occurs it
will not affect the performance of the application. Along with that incorporating 3-tier
concept will expand the scalability of the application in order to handle more network traffic
and increase the capabilities of load balancing.
