Case study of spiral process model
Using the railway reservation system
THE RAILWAY RESERVATION SYSTEM
My case study is on railway reservation is based on spiral model which they are already
exist.There are two method of railway reservation system online booking and counterbooking.
INTRODUCTION
Indian railway reservation system is power full system because Indian railway carries about 6
lakh passenger is reserved accommodation every day. The computerized passenger
reservation systems facilitate the booking and cancellation of tickets from any of 3500
terminals. These tickets can be booked or cancelled for journeys and one is major thing is that
railway quota and railway employees are facility to free of cost journey. Indian government
gives so many facilities for booking.
BOOKING FACILITIES OF RAILWAY RESERVATION
Counter Booking
The railway gives facility of counter booking. Counters are found on the station or in any mid
palaces of cities. These is the oldest method of booking the tickets the reservation counter are
there at railway department from where people can get the ticket to their respective
destination.
Online Booking
This facility help the people for book their tickets online through internet, sitting their home
by a easy formality or we say that on a single mouse click. Using their credit cards people can

easily get there tickets with in a minutes. There are certain charges for online booking as well.
Online booking system is user friendly and fast.
FUNTION OF RAILWAY RESERVATION SYSTEM
 It reserve and cancel seat for the passenger
 It contains information about the trains.
 It contains details of reservation fees, concession and railway employee’s facility.
 It makes entries for reservation, waiting, cancel tickets.
 It will update for uptime and downtime.

ANALYSIS OF PROBLEM
The problem with the system can be automated. As well to make it more efficient in use to the
people who want to save their time and extra money also.
In online railway reservation system for booking the tickets online the instanced user has to
enter details like their username and password.
Once the username password are verified then he is allowed to enter the main system the
destination date and no. of tickets.
For money purpose he is asked his/her payment details.
The user is also provided with a provision of canceling the reservation where is the amount is
credited back to his account.
SOFTWARE PROCESS MODEL
The spiral model combines the idea of iterative development with the system systematic,
controlled aspects of like waterfall model.
Very high emphasis on risk analysis.
It allow for increment release of the product or increment refinement through each iteration
around the spiral.
Changing requirements can be accommodated
Allows for extensive use of prototype.
Requirements can be captured more accurately.
Development can be divided into smaller part and more risky part can be developed earlier
which help better risk management.
When costs ther is a budget constraint and risk evaluation is important.
Long term project commitment because of potential changes to economic priorities as the
requirement change with time.
Customer is not sure of their requirement which is usally the case.

IDENTIFICATION/CUSTOMER COMMUNICATION
In this phase have requirement identify an effective communication between the developer
and user, also the because of whole project is this region the problem identification and
requirements finding done ever here.
DESIGN
Design phase start with the conceptual design in the baseline spiral and involve architecture
design, logical design of modules physical product design and final in the subsequent spirals.
CONSTRUCTION OR BUILDING
It required to construct using various technologies at front end backend of the syste, testing of
that and provide user support.
EVALUATION AND RISK ANALYSIS
Risk analysis includes identifying, elevating and monitoring technical feasibility and
management risks.
The customer evaluate the software and provide feedback.
