Overview of MVC Architecture

MVC Architecture is the Architecture which is used in the software industry to develop

software.MVC means Model-View-ControllerThe View Component is the User Interface with

which the user interacts.Controller component is the component which interacts with Model

and calls all the modules.The Model component is the component which comprises of all the functional modules,it is the heart of

any Application which implements MVC Architecture.

Implementation of MVC in Airline Reservation System

We have implemented MVC Architecture in our project by using JSP,Servlets and POJOs.In our

system the JSP pages comprises the view component that displays the User

Interfaces.We have one Servlet which acts as the Controller it is a .java file with a doGet()

method.Our POJO file acts as the Model where all the functions have been declared

Description of Model Component

In our Airline Reservation System we have one POJO file i.e Airline.java which contains all the

functionalities like addPassenger(),addNewPassenger(),CancelTick

et() etc.This file interacts with the Controller which in turn interacts with the JSP pages

Description of View ComponentWe are using JSP Pages which acts as the user interface for the passenger and the administratorThe list of JSP Pages are:•Welcome.jsp•Menu.jsp•SearchFlight.jsp•BookTicket.jsp•InventoryManagement.jsp•FareManagement.jsp•CancelFlight.jsp etc...

Description of Controller:

We are using one Servlet file as our Controller which is AirlineServ.java.This file interacts with

the User Interface i.e the JSP pages and the Model Component i.e Airline.java file.The Servlet invokes all the components of the

Model Component after taking the necessary details from the User Interface i.e the JSP pages

Screen shots:

Future Scope of development:• The user interfaces generates alert boxes for

wrong Input in the input fields. The book ticket user interface can be made more user interactive by adding more client side validations.

• The session for the Clients are efficiently managed .so it can be deployed on the web server after adding some more security features like URL encoding.

• Postponing or preponing a flight can be added to this system
