Introduction

Purpose:

The purpose of Railway Reservation System is to create Reservation, Cancel Reservation, Viewing Train Information, Viewing Reservation Details, Updating Train Information, Updating Reservation Details and Generate Reports.

Scope:

            Reservation Clerk is a person to create and Cancel Reservation by entering Login Password. Manager is a person who updates the Train Information by entering his own Password. The system can handle only reservation and train details efficiently and it doesn’t contain other details about the railway administration. The main purpose of this system is 

Ø  Creating reservation

Ø  Cancel reservation

Ø  View reservation status

Ø  View train schedule

Ø  Generating reports

Ø  Update train schedule

Ø  Update reservation details

            The Seats of Reservation cannot be more than the seats of Train at that date. This is a constraint that has to be followed by the Clerk when he creates the Reservation. For that purpose he wants to check the seats remaining present in the Train.

            The scope of this system in creating Reservation is that, from any Railway Station we can Create Reservation, which is updated automatically in all the stations. Hence, there is no confusion to the Reservation Clerk in all the stations to create the Reservation. This can be possible by maintaining Global Database. Clerks present at different stations can access the global database and the clerks can easily understand the remaining reservation seats. It provides the ability to create reservation from different places for a train.

            The system is so secured and clerk and manager utilize it. Nobody can able to access the system without his or her permission because of providing login facility to the system. The password is in the form of cipher text by using cryptography technology, so it cannot be hacked by any person. The global database can passes through network in order$to utilized!bymanagers!or clerks at different places. So, we want to provide network security because of the data not hacked by the other persons when it is going through network cables. This network security is pzovided by the cryptograrhy technology.

1. Create Reservations:       A passenger should be able to reserve seats in the train. A reservation form is filled by the passenger and given to the clerk, who then checks for the availability of seats for the specified date of journey. If seats are available them the entries are mode in the system regarding the train name, train number, date of journey, boarding station, destination, person name, sex and total fare. Passenger is asked to pay the required fare and the tickets are printed. It the seats are not available then the passenger is informed.

2. Cancel Reservation:         A passenger wishing to cancel a reservation is required to fill a form. The passenger then submits the form and the ticket to the clerk. The clerk then deletes the entries in the system and changes the reservation status of that train. The clerk crosses the ticket by hand to mark as cancelled.

3. Update Train Info:            Only the administrator or manager enters any changes related to the train information like change in the train name, train number, train route etc. in the system.

4. Generate Report:            Provision for generation of different reports should be given in the system. The system should be able to generate reservation chart, monthly train report etc.

5. Verify login:          For security reasons all the users of the system are given a user id and a password. Only if the id and password are correct is the user allowed entry to the system and select from the options available in the system.

            The basic actions that are performed by the system is given as follows:

Ø  Verification of user

Ø  Maintain Reservation details

Ø  Maintain Train details

Appendices

Input/Output formats:

            The input format for the system is given as follows:

Ø  Login Screen

Create Reservation

Output format for the system contains the following screen

This is the form that is to modified the train details. This form consists of no of seats textbox, which shows the remaining seats present in the train. The no of seats value is automatically changed when we create or cancel reservation. This is the form which consist of two buttons for the purpose of create reservation and to cancel reservation. When the seats text box has value zero than its, says no seats are remaining in the train to create reservation.
