This document describes an airline reservation system project created by Zornitza Panayotova for a CS 441 class. It includes 19 requirements for the system, which allows users to search for and reserve flights online. The system design uses a 3-tier architecture with Java, HTML, JSP and servlets. It includes tables to store available flights, schedules, customers and reservations in a Microsoft Access database. The document provides examples for testing flights, discounts and cancelling reservations.

1. Overview
The Airline reservation system is a Web-based on-line reservation system that
is intended to provide information needed to reserve seat(s) on certain flights.
This project is based on the 3-tier architecture. It is a pure
JAVA/HTML/JSP/Servlet solution.
2. Project requirements
[ REQ-1] Each flight has a limited number of available seats. There are number
of flights that go from/to different cities at different dates and time.
[ REQ-2] The server shall maintain a table for the list of available flights where
each row within the table has the following fields: Flight number,
Departure city, Destination City, Departure date, Departure time,
Arrival date, Arrival Time, Capacity, and Available seats. The values
within this table will be hard coded.
[ REQ-3] The Server shall maintain a table for the customers where each row
within the table has the following fields: Confirmation number,
Customer Name, Customer Address, and Departure Flight Number.
The values within this table will be created when the user makes a
reservation.
[ REQ-4] The confirmation number is a string that is composed of the date
(mmddyy), time, flight number, and a random number in the range [1-
5000].
[ REQ-5] Assume the customers are interested always in one-way trip
[ REQ-6] Have at least 50 flights in your database.
[ REQ-7] For the user interface, You have to give an option for departure city
[ REQ-8] For the user interface, You have to give an option for arrival city
[ REQ-9] For the user interface, You have to give an option for departure date
[ REQ-10] For the user interface, You have to give an option for departure time
[ REQ-11] Once the user makes the selection for departure/arrival city and clicks
the OK button you will contact the server in order to see if there are
such flights available in the database, and if there are, then the server

will calculate the fare and send them to the client that will display
them for the user along with departure/arrival time from/to
departure/destination cities. Within this page, you will have 2 buttons:
Reserve or Cancel.
[ REQ-12] If the user selects the reserve button of the previous requirement, then
a new page will be displayed that will prompt the user to enter the
following: Customer Name, Customer Address, Customer Credit Card
Number, and a Submit Button.
[ REQ-13] Once the user selects the Submit button of the previous requirement,
then the client will send the information to the server and in return
gets back a confirmation number that it will display for the customer
and provide an OK button in order to return to the home page.
[ REQ-14] The user should be provided with a panel that will allow the user to
cancel certain reservation.
[ REQ-15] Once the user enters a confirmation number to cancel the client will
send this confirmation number and the server will delete this
reservation from its customer table.
[ REQ-16] The user shall provide a valid confirmation number in order to cancel
certain reservation and if the user enters an invalid confirmation
number and error message shall be displayed for the user.
[ REQ-17] To minimize number of flights that are less than half full, we are
interested to display on the main page of our system, special offers for
those flights that meet the conditions specified in the following
requirement.
[ REQ-18] If there are certain flights that have the following condition: (0.33 flight
capacity < number of reserved seats < 0.5 flight capacity) && ((current date +
5 days) = departures date))). Then you need to display ads in the home
page of the airline reservation systems about these flights that are
priced at a discount of %30 of their original price, in order to
encourage customers to buy tickets on that flight.
[ REQ-19] The ads in the previous requirement shall not be hard-coded and shall
be selected randomly.

[ REQ-20] Once the user clicks on the ad, it will display the page about that flight
and the ability to reserve seats on that flight. In other words there shall
be a reserve button on the displayed page.

4. Testing Examples:
All data in the database are for flights for 12/7/2002 and
12/8/2002. If you want to test the system you have to select for
Departure date either 12/7/2002 or 12/8/2002. The
commercials for discount flights can be seen only if the system
date is 12/2/2002 or 12/3/2002.
v Test for no flights found:
- Chicago to San Francisco for any date;
- any flight with date other than 12/7/2002 and 12/8/2002;
Zornitza Panayotova 11 12/05/02

12. Illinois Institute of Technology CS441 Project
v Test for flights in the morning, noon, afternoon or evening:
- New York to Chicago on 12/7/2002 or 12/8/2002;
- Miami to Chicago on 12/7/2002 and 12/8/2002;
v Test for Discount flights:
- Because all data are for departure dates: 12/7/2002 or
12/8/2002 you can see the randomly selected commercials only
if you system date is 12/2/2002 or 12/3/2002. Every time when
you test it you need to change the system date (see [Req. – 18]).
v Test for Cancel Reservation:
- Enter to test Cancel Reservation: 120202ars0084022.
