SECTION 1
Introduction
System architecture also known as systems architecture is a model of concepts which states the
structuring of the system ,its behaviours and its view . In this report the system architecture of airline
reservation system is discussed .The airline reservation system is developed not only to book flight
tickets but also use to guide different tasks related to management of airlines. The system also imparts
rates and directory in real time for the passengers and the travelling agents. It will also helps the
passengers in finding the details of several other ticket booking flights which in turn helps them to book
their ticket from the one that they found suitable enough. This is how the airline system works.[1]
Figure 1

The airline system consists of three main components given below
 ADMIN
 USER
 SERVER
ADMIN
The first important component of the airline reservation system is admin who is responsible for
managing all the activities that are going on the system. The admin can fully operate the system and also
controls the functionality of the system.
USER
The second most useful component of the system is the user who uses the information given in the
system. User can login and logout from the system as and when required. They can surf the system
according to their needs.
SERVER
The last component of the system is server which keeps all the records of the individual who access the
system.Informtion that are needed to be fetched can be retrieved from the component server.

TIERS OF THE SYSTEM
The airline reservation system consists of three-tiers in its architecture namely
1. Presentation Tier
2. Business Logic Tier
3. Data Access Tier
Tiers of the Architecture
PRESENTATION TIER
BUSINESS LOGIC TIER
DATA ACCESS TIER

1.Presentation Tier
The presentation tier is the first layer of the system architecture of the airline reservation system. In this
layer all the information related to buying and searching for tickets are display in the human
understandable form. It basically, provides the user interface of the system in which main focus on the
presentation of the content in attractive and catchable manner.It establishes the interaction between the
remaining two tiers[1].
It also interacts with the client tier by sending the output results in them.This layer helps the user to
communicate with the system easily as its appearance is catchy and easy to use .Presentation layer is the
utmost important layer in the architecture[1].
2.Business Logic Tier
The Business Logic tier is the second most important tier of the architecture.It is also known as middle
layer tier. The main role of this tier is to handle the information which is transferred among the database
and the user through presentation layer.The database stores all the information related to the
system ,when the user enters its detail in the presentation layer which further transfer the information
of user to the business logic layer[1] .
This layer further transfer the received information through presentation layer to the data access layer
which stores all the information of the user and provides them whenever they need.
3.Data Access Tier
The data access tier is the third or the last layer of the architecture. This layer contains the information
related to the reservation system in the servers of data that is available in this layer. All the information
that the user enters in the presentation layer of the system are directly stored in this layer with the help
of business logic layer and can also be fetch from this layer.
It is the final layer of the system and the most essential too,as this layers cumulates the data of those
individual who are accessing the system . With the help of this layer user will be able to find that how
many flights available ,delayed, or have been booked [1].

Overall structure of the implementation
The structure architecture of an airline reservation system consists of three features that is admin,
customer and database. In this section the description of how the system is implemented is being
discussed, whenever the client wants to use the system he will enter his details in the system which will
generate data by fetching the required information from the database .All the information present in the
system is solely handled by the admin of the system. This is how the system works .System will also
update the current status of the flights weather it is available at the moment or not, if delayed for some
reason or any necessary details related to the flights. [2]

CLASS DIAGRAM
A class diagram basically describes the structure of the system. It also elaborates the details of the
classes and its attributes, functions and also the relationship between the objects .
