Online Ticket Reservation System. And also to draw E-R
diagrams, DFD, CFD and structured Charts for Online
Ticket Reservation System
Exercise 3: Online Ticket Reservation System (Railway)
Dr. G. Prasuna, Associate Professor, CSE Dept., St. Ann's College of Engineering and
Technology, Chirala
Problem Statement For Online Ticket Reservation System:
The Online Ticket Reservation System is Train Reservation System where
the passengers can reserve the train tickets in for their travel, cancel the reserved
train ticket, View and print train ticket.
The passenger who is reserving the train ticket in Online Ticket Reservation
System should be the member of Online Ticket Reservation System. The
passenger can reserve the train ticket by giving the required details like source,
destination, date of journey and know the trains list. The passenger can select
train and check availability. If available, give passenger details in the form,
payment details and submit it for the processing. The Online Ticket Reservation
System provides train ticket which passenger can view and take print.
Dr. G. Prasuna, Associate Professor, CSE Dept., St. Ann's College of Engineering and
Technology, Chirala
The administrator of the online ticket reservation system can control the
ticket reservation and the accounts of the passengers who are signing up in
online ticket reservation system. The administrator can reset the seats, fares
of the tickets. The sole control of the system is handled by the administrator.
The passenger can sign in for any number of times for reserving,
cancelling and viewing the train tickets. The system tracks for the database
any number of times for reserving, cancelling and status viewing. The
passenger can see the status of the classes that are available in the train which
he is going to travel by noticing the number of seats details from the display
board. The cancellation of the train tickets is also very easy so that the
passenger can cancel the tickets that he has booked.

2.4 Operating Environment:
The online ticket reservation system is an internet oriented application, it set to operate on a
high available and Qos network, since registration is a sensitive thing, the quality of the
network should be Good for this process. Mostly a device that can access the internet and can
support a huge web application for registration. Any OS can support this system as it is not
particularly software or hardware dependent.
2.5 Design and Implementation Constraints:
The system is internet based system, a webapp that should be developed to support any web
browser to be used. Passenger Account and Payment for train ticket should be secure , the
system design should include a lot of DB and SYSTEM validation. Developers needs to be
always there to support the delivered system in terms of validation and maintenance.
