With the advent of various programming technologies
and their broad support toward a lot of stuffs, our needs have escalated over
the years, making computers our friend, relative, and teacher and guides many
times. The need for integrating our daily used Services to these machines
(means computers) has become more and more important. Finding the various
fields of application for the use of this revolutionary machine is not a new
era of research, but even now it has much potential to attract the programmers for
making it more functional for simplifying their daily life tasks. Such a field
of application is client server. It was very much expected that this technology
was going to explode at a day making the whole world crazy for it, but now this
craziness is a never ending one, after getting into transport control protocol
technology. Computers are a strong medium of communication, are they getting
challenged by the client server technology? No one thinks so, because client
server application are trying to come out from some limitations where computer
user trying to find their new uses every day.
Software
development has a strategic importance in the present scenario this project “IMPLEMENTATION AND DESIGN OF CHAT SERVER” has
been developed to subdue the flaws in the existing system.
This
software is developed in JAVA and SQL server is very much user friendly and
secure. Several feature of this software is designed to make it particularly
easy for every one who is going to use this software.
This
software is much user friendly, every one who is going to use the software.
Helped manuals are provided in which instruction and help is given to use
software.
INTRODUCTION
Teleconferencing or Chatting, is a method of using
technology to bring people and Ideas “together” despite of the geographical
barriers. The technology has been available for years but the acceptance it was
quit recent. My project is an example of
a chat server. It is made up of 2 applications the client application, which
runs on the user’s Pc and server application, which runs on any Pc on the
network. To start chatting client should get
connected to server where they can practice two kinds
of chatting, public one (message is broadcasted to all connected users) and
private one (between any 2 users only) and during the last one security
measures were taken.
Today’s commercial world is much
dependent on information, not only the information but also the cheapest,
fastest, and reliable source of getting information. We can say that we are
living on information age. We live in the age where everything depends upon how
we can get information of our need in quick time. Hence there is a need of not only getting the
correct information but also in a short time. We cannot utilize the information
that is not obtained faster enough.
The computer has changed the way we
work, learn and communicate. Virtually every kind of organizations throughout
the world conducts its business, find the solutions of the problems and acquire
knowledge through the computers. Computer based systems are now at the heart of
daily activities and a major considerations in decision-making process.
Now days there are various
means of communication or getting information like landline phones, mobile
phones, fax etc but the communication through computers is proved the cheapest
and reliable one. By using computer one can not only exchange voice services
but can also send files, pictures, video clips, multimedia files from one
computer to another connected via a network. The two computers must be
connected with
each other via a network. The two
computers can be too far from each other or to close to each other and chatting
is the best communication way to connect each other. More than two people can
also communicate with each other at time. Chat is probably the most intimidating part of the whole Internet
because people can and do watch you. If you're lurking, they know. If you say
something stupid, they hear. It's the place where you are most likely
to inadvertently injure someone, or have someone tear a chunk out of you. It is
also the best place online to form friendships, and one of the few place in
cyberspace where folks think to have weddings.
OBJECTIVE
The main
objectives of this project is to develop a fully chat server that works as an
expert system. This system provides an easy-to-use, faster, efficient and
robust platform for the users. The user can use this for chatting references will
have to be taken from the existing system and develop a computer-based chat
server.
The Other objective of
this project is to provide users a cheap, reliable, and convenient way to
communicate with each other using computer systems. I want to allow my users to
participate in instant message communications with other community members. Chat
applications allow inexpensive and efficient social interactions between
communities members spread across the globe.
A community can use the Chat application to allow its members to have an
interactive session with a special guest or a community member through the
means of a moderated chat. A customer support site can use the Chat application
to offer instant responses to
its customers regarding its products. Chat Server is a computer system in a network, which has ability to connect
many clients and accept their request and process it. Clients can share the
resources of the server in a networked system. Through this project we can
communicate with other persons (clients) in the network, which is a cheap and
reliable means of communication because here we are connecting too many clients
at a time by using only one communication line. It is reliable because we can
save the chat session. And also it is providing more facility because we can
also send text files etc. to the other person in the network. We can use his
means of communication in an organization for communication with the employee’s
and manager’s rather than to communicate by using a dedicated phone line. In
all we can say the project is providing a cost-effective and fast means of
communication.
Software development has a
strategic importance in the present scenario. This project “CHAT SERVER” has
been developed to subdue the flaws in the existing system.

PRODUCT FUNCTION
‘Chat Server’ can
perform a host of functions which are relevant with the nature of the software.
Addition of records makes possible to add more records of users which want to
chat to the other users. Additions are done with the integrity issues kept in
mind.
·
USERS
The software targets all those
users where users want to interact with other user by chatting on web. The user
should have only basic knowledge of computer to use software.
·
GENERAL CONSTRAINTS
The software framework that ‘CHAT
SERVER’ is relied upon is the availability of GUI. The software is designed and
coded to work in any environment and is compatible with WINDOW operating
system. There are no hardware constraints.
·
ASSUMPTIONS
The Chat Server does not present an
absolute solution. It was designed by keeping the target in mind. The structure
and format of software adheres to what is required by any particular user.

ALGORITHM
USED
Knowing sockets, protocols, and network programming
does not mean that you can easily create a chat server. How you are going to
send and receive data. What kind of synchronizations exists between the server
and the client application? This section will show how this server is build and
what algorithm it follows.
1.
Project Structure
Since we are using the TCP/IP facilities, we are
obliged to divide the project into two
applications. In the next few sections we are going
to explain how these applications works and how they are synchronized with each
other.
1.1.
Client
In the client form first open Chatter Box. In Chatter
Box is divided into four sections. First is new user, Second is login name,
Third is log off and fourth is add remove contact. To get connected to server
you just enter a login name then open chatter box. During this
connection operation, the client will send a data
“login name” indicating to the server that
there is a new chatter. The server will parse this
string and call the “User In” functions which adds this username to his list
and retransmit another identical control string to all Connected users containing
all the usernames in order to update the “Connected users list” in the client’s
form. The same thing happens when the user wants to disconnect him.
1.2.
Server
Till now it is clear that
the server application has dual job, one to receive data And another
to transmit data. In fact
it plays the role of a “traffic officer” (Putting everything in order the right
order). Since all the chatting operations Are passed through the server, then
the main job of server is responding to the Control strings sent by clients. It
plays an important
role during the private.
2.
Private chatting
Writing in the send text
box and then hitting the enter button in keyboard. Whenever a client wants to
initiate a private session, in the list of connected users, he double clicks
the username he wants to chat with. Two phenomenon’s’ Will take place. First,
open a local-private session window. Second, to tell the Server that he wants
to chat privately in order to open a remote private Window. When these
conditions are satisfied, private chatting can be practiced by just
