INTRODUCTION TO THE RAILWAY RESERVATION SYSTEM:
The Indian Railways (IR) carries about 5.5 lakhs passengers in reserved accomodation every day.The Computerised Passenger Reservation System(PRS) facilates the booking and cancellation of tickets from any of the 4000 terminals(i.e. PRS bookin window all over the countries). These tickets can be booked or cancelled for journeys commencin in any part of India and ending in any other part, with travel time as long as 72hours and distance upto several thousand kilometers.
The project of PRS was launched on 15th November 1985, over Northern Railway with the installation of Integrated Multiple Train Passenger Reservation System(IMPRESS), an online transaction processing system developed by Indian Railways in association with Computer Maintenance Corporation Ltd., at New Delhi. The objective was to provide reserved accomodations on any train from any counter,preparation of train charts and accounting of the money collected. The application was implemented in 1987 Mumbai,Chennai,Kolkata,Secunderabad subsequently.
RAILWAY RESERVATION METHODS:
ONLINE BOOKING: With the help of this people can book their tickets online through internet, sitting in their home by a single click of mouse. Using their credit cards people can easily get their tickets done within minutes. There are certain charges for online booking as well.
COUNTER BOOKING: This is the oldest method of booking the tickets. The reservation counters are there at railway department from where people can get the tickets to their respective destinations.
Railway passengers frequently need to know about their ticket reservation status, ticket availability on a particular train or for a place,train arrival or departure details, special trains etc.. Customer information centers at the railway stations are unable to serve such queries at peak periods.
The number of the reservation counters available to the passengers and customers are very less.
On most of the reservation systems there are long queues, so it takes a long time for any individual to book the ticket.
As now there are no call centers facilities available to solve the queries of the passengers.
In Online Railway Reservation System,for booking the tickets online the intended user has to enter details like username and password.
Once the username and passwords are verified then he is allowed to enter the main system wherein he can select the destination, date and no of tickets.
For the purchase of the tickets he is asked for payment details (like credit card details etc).
The user is also provided with a provision of canceling the reservation where in the entire amount is credited back to his account.
The analysis part also comprises of the UML diagrams that boost the program.
USE OF SPIRAL MODEL
A spiral model is divided into a set of framework activities defined by software engineering terms.
As the evolutionary process begins, software team performs activities that are implied by a circuit around the spiral in a clockwise direction, beginning at the center.
The first circuit around the spiral might result in the development of a product specification; subsequent passes around the spiral might be used to develop a prototype and then progressively more sophisticated versions of software.
Unlike other process models that end when software is delivered, the spiral model can be adapted to apply throughout the life of the computer software.
Every new step is dependent on the previous step and moves spirally outwards.
At any point in the system we can return back to the previous step.
Because software evolves as the process progresses, both we and customers can better understand and react to the risks at evolutionary level.
In the case of errors we can easily trace the root cause of errors.
Spiral model is very realistic approach towards the process development.
Our project is only the gist of the online reservation system.
Due to time constraints it was not possible to incorporate all the concepts related to the topic.
So the program created is just an instance of the Original Online Railway Reservation System.
