Online Room Reservation System
Business Description
As collaboration and group projects have become more common at Client. Miracle software
and services has seen a steady increase in the number of users seeking group work space.
Currently, large tables and comfortable seating areas are available to accommodate groups,
but in the Fall 2007, Client will open group work rooms for its employees, clients and
business meetings. These rooms should provide more freedom and flexibility for group
work.
Problem:
In order to open these rooms as soon as possible, room reservations initially were been
handled at the reference desk located on the same floor as the room, with reservations made
in person or over the phone and recorded on paper. Anticipating heavy usage, Client would
like to centralize the reservation process, and allow reservations to be made online.
The main purpose of the Online Room Reservation System is to allow Client employees, and
clients to reserve a group work /collaborative work room online. To make a reservation, a
user will simply need to login, select a reservation date and time, and confirm the reservation.
When logged in, a user can also view, modify, and delete existing reservations. The system
will also send users a reservation reminder email.
Additional features of this Room Reservation System include browsing and searching the
room schedules and viewing room features. Browsing the schedules allows the user to see
room availability for a particular day. To search the schedules, a user selects a date and time.
If a room is available, the user is allowed to make a reservation, but if a room is not available,
the user has the option to search for another date and time or to browse the room availability.
Viewing room features allows the user to read about the group work rooms and watch a short
video clip showing a room.

Online Room Reservation System
The Room Reservation System administrator has additional privileges. The administrator
can view, modify, and delete reservations made by anyone, and the administrator can print a
daily schedule for each room to post outside each room. A variety of reports can also be run
by the administrator.
Client is excited about the Room Reservation System. The system will benefit users by
allowing them to create, modify and delete reservations online, and the system will benefit
the Company by centralizing the reservation process and allowing reports to be easily
created.
User Population
Users for this system are Miracle software systems employees (Managerial, Technical,
Clerical so on), and Customers/Clients. User population using the system at the same time is
expected to be 30 – 40 people.

Online Room Reservation System
AJAX framework in Online Room Reservation System
AJAX Technology has been implemented in „Search Room Availability‟ feature
Why AJAX?
The page-reload cycle presents one of the biggest usability obstacles in Web application
development and is a serious challenge for JAVA developers. AJAX (Asynchronous
JavaScript and XML) is a programming technique that lets programmer combine Java
technologies, XML, and JavaScript for Java-based Web applications that break the pagereload paradigm.
How AJAX is different?
An Ajax application eliminates the start-stop-start-stop nature of interaction on the Web by
introducing an intermediary – an Ajax engine – between the user and the server. It seems like
adding a layer to the application would make it less responsive, but the opposite is true.
Instead of loading a webpage, at the start of the session, the browser loads an Ajax engine –
written in JavaScript and usually tucked away in a hidden frame. This interface in responsible
for both rendering the interface the user sees and communicating with the server on the user‟s
behalf. Ajax engine allows the user‟s interaction with the application to happen
asynchronously – independent of communication with the server. So, the user is never
starting at a blank browser window and an hourglass icon, waiting around for the server to do
something.

Testing and Error Correction
Following Tests have been conducted on the Online Room Reservation and the System has
passed all the tests
1) Unit testing
2) White box testing
3) Black box testing
Unit Testing: It is a procedure used to validate that a particular module of source code is
working properly. In this system, both the Administrator and User module have been tested
separately. Here, making a reservation, deleting a reservation, adding new user to the system
have been tested. All the features have passed the testing.
White box testing: Specifics of programming code is checked and output is examined. It
requires programming skills to identify all paths through the software. In this system all the
structural and logical code has been tested and the system passed the testing.
Black box testing: Internal code of the system is not tested but the system is tested for some
set of input and checked if desired outputs are obtained. Online Room Reservation system is
been tested for random user names and passwords, illegal dates (dates prior to current date),
incorrect input values. System could withstand for most of the test procedures, except for
illegal dates. Measures have to be taken to correct them.
35
Online Room Reservation System
Sample Screens and Reports
In this system, Administrator has the privilege to print-out a summary of all the reservations
made. Reports that are generated give a detailed list of all the reservations made and available
slots. Also, regular user can print their reservation confirmation page for their records.
(Available slots are marked as ‘Free’ and occupied slots are marked in RED)

Online Room Reservation System
Conclusion
Online Room Reservation System has all the capabilities to manage registrations online. This
system makes it very easy for the employees of Client to reserve collaborative work rooms
with a simple click of mouse. Problem which Client faced in maintaining registers and floor
keeps is now solved. They can now centralize the registrations by having this online
maintenance system. Administrator has the privilege to make detailed summary of room
occupancy and document them for future purposes. This system not only makes things faster
but also gives the employees flexibility to cancel and back out their reservation with a single
click.
Future Scope – A Networked World
In today‟s world if we are serious about our business we cannot afford to overlook the huge
potential that online reservation systems offer. We can have our own online reservations
system working for us 24hrs a day, 7 days a week, 365 days a year! Logic used in this system
could be applied to build many applications such as: „Online appointment system‟, „Online
time cards submission system‟, „Online bulletin board system‟ so on. As far as this system is
concerned, it could make use of video streaming to view interiors or equipments available in
the room and also this system could be enhanced by giving a „waiting list‟ feature. Whenever
a reservation is dropped the next available person in wait list can make booking for that time
slot. Like this, many more advances can be made by the current system.
