Case Study Problem Statement for Railway Reservation System

oftware has to be developed for automating the manual railway reservation system.
The system should be distributed in nature. It should be designed to provide
Sfunctionalities as explained below:
1. Reserve Seat: 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 then the
entries are made 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. If 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 Information: Only the administrator enters any changes related to the
train information like change in the train name, train number, train route, etc. in the
system.

4. Report Generation: 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. 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.
6. View Reservation Status: All the users should be able to see the reservation status of
the train online. The user needs to enter the train number and the pin number
printed on his ticket so that the system can display his current reservation status like
confirmed, RAC or Wait-listed.

train schedules for the entire train network. The user should be able to see the train
name, train number, boarding and destination stations, duration of journey etc.

10.3 Summary

System conception is considered as a requirement analysis phase.

Requirements describe how system behaves from the user’s point of view. True customer
requirements should be separated from design decisions.
Elaboration is the point where you want to have a better understanding of the problem.
