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. Our project is an example

of a chat server. It is made up of 2applications the client application, which runs onthe users Pc and server application, whichruns 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.

This report details the work done towards the project "Online chatting".

This particular project is a solution developed to communicate between the user

across worldwide through Internet. The concept of sending letters and telegraphs

has been reduced due to the new era of Internet Mailing. One such facility is being

provided by the Chat Server. A message or information can be sent via many

Medias, such as it can be telephonic, telegrams, fax etc to the recipient. Each such

information requires a high level of security. To maintain such security and smooth

completion of any communication it requires more time and human effort in manual

system.

"Online chatting" automates all the aspects stated above related to a communication

in a highly secure environment. This project has been developed to receive instantand urgent messages and to provide total user satisfaction.

The entire process has been automated using PHP technology and MYSQL

SERVER to smoothen the flow of information in a highly secure environment

across the network. The solution has been deployed, tested and validated

thoroughly. While designing the system, care has been taken in efficiency,

maintenance and reusability of the software for the present and future changes in

the system.

SYSTEM ANALYSIS

SYSTEM OBJECTVE

Communication over a network is one field where this tool finds wide

ranging application. Chat application establishes a connection between 2 ormore systems connected over an intra-net or ad-hoc. This tool can be used for

large scale communication and conferencing in an organization or campus of

vast size, thus increasing the standard of co-operation. In addition it converts

the complex concept of sockets to a user friendly environment. This software

can have further potentials, such as file transfer and voice chatting options

that can be worked upon later.

SYSTEM ARCHITECTURE

The chat application works in two forms:

List form:

In this form, all the names of the systems connected to a

network are enlisted. These names can later be used for

communication with the help of mouse event, or in simple

language: a click or a double click.

Chat Form:This form is called only when an element is selected from the

List form. In this form, a connection is created between the host

system and the selected system with the help of a socket

Operational Concepts and Scenarios

Operation of the application based on the inputs given by the user:

List Form:

When initialized, returns a list containing the names of all the system

connected in a network.

Contains two buttons: Refresh and Connect.

When Refresh button is clicked refreshes the list of names.

When the Connect button is clicked or a name is double clicked, the

chat form is initialized with a connection between the host and the client

machine.

Note: If no name is selected, and connect button is clicked an error box isdisplayed.

Chat form:Contains a rich textbox which cannot be edited but only displays the

messages from one user to another, including the self sent message, as in

any chat application.

Contains a textbox for messages to be written that is sent across the network.

Contains a Send button.When the sent button is clicked, in the background, the text in the textbox

is encoded and sent as a packet over the network to the client machine.

Here this message is decoded and is shown in the rich textbox.

To make it more realistic, the self sent message is shown in the rich textboxas well. Boththe messages is differentiated by the help of the identifier name at the

beginning of each message in the rich text box.

EXIT:The user exits the software in two scenarios:

Exits the chat form, the list form remains intact. Exits the list form,

this is when the application is closed.

TECHNICAL DETAILS

To complete the entire project, in the front end we used PHP, CSS, and HTML5

and in the back end we used Mysql server to maintain the database. We designed

our page by using HTML5 and CSS. For design purpose, we have used

Dreamweaver software. The project is developed in a single window.

Reasons for choosing php:

PHP is Powerful, Robust and Scalable.

It is a general-purpose server-side scripting language originally designed for

web application and website development.

PHP runs on all most popular web servers and many different operatingsystems, which helps to create large and complex web applications or

websites.

Reasons for choosing Mysql as Backend:

Because of its rich features in manipulating, securing and managing

data.

Faster and better transactions.

Scalability and flexibility.

Web and data warehouse strengths.

Comprehensive application development.

Socket Overview

A socket is an object that represents a low level access point to the IP stack. This

socket can be opened or closed or one of a set number of intermediate states. A

socket can send and receive data down disconnection. Data is generally sent

in blocks of few kilobytes at a time for efficiency; each of these block arecalled a packet.

All packets that travel on the internet must use the Internet Protocol. This

means that the source IP address, destination address must be included in the

packet. Most packets also contain a port number. A port is simply a number

between 1 and 65,535 that is used to differentiate higher protocols. Ports are

important when it comes to programming your own network applications

because no two applications can use the same port.

Packets that contain port numbers come in two flavors: UDP and TCP/IP. UDP

has lower latency than TCP/IP, especially on startup. Where data integrity is not

of the utmost concerned, UDP can prove easier to use than TCP, but it should

never be used where data integrity is more important than performance; however,

data sent by UDP can sometimes arrive in the wrong order and be effectively

useless to the receiver. TCP/IP is more complex than UDP and has generallylonger latencies, but it does guarantee that data does not become corrupted when

travelling over the internet. TCP is ideal for file transfer, where a corrupt file is

more unacceptable than a slow download; however, it is unsuited to internet

radio, where the odd sound out of place is more acceptable than long gaps of

silence.

UDP Ports

The User Datagram Protocol is an unreliable, connectionless oriented protocol

that uses an IP

address for the destination host and a port number to identify the destination

application.

The UDP port number is distinct from any physical port on a computer such as a

COM port or an I/O port address. The UDP port is a 16-bit address that exists

only for the purpose of passing certain types of datagram information to the

correct location above the transport layer of the protocol stack.

A UDP datagram header consists of four (4) fields of two

bytes each:

1. source port number

2. destination port number

3. datagram size

4. checksum

FEASIBILITY STUDY

Feasibility is the determination of whether a project worth nothing. Once

preliminary area of application has been defined its subject to a more rigorous

examination in a feasibility study. In conducting the feasibility study three types of

feasibility can be considered. These are Technical feasibility, Economical feasibility

and Operational feasibility.

TECHNICAL FEASIBILITY

Technical feasibility is concerned with specifying equipment and software

that will meet the requirement and goals. The analyst must find out whether

current technical resources can be upgraded or added to in manner that fulfills the

requests under consideration. However add-ones, to existing systems are costly

and not worth wide simply because they must need inefficiently. If existing

systems cannot be added onto, then the next question becomes whether there is

technology in existence that needs the specification.

ECONOMICAL FEASIBILITY

Economical feasibility is the second part of the resource determination. The

basic resources to consider are, the time and that of system analysis team, the

cost of doing a full system study, estimated cost of hardware, and estimates costof software and/or software development.

ENTITY RELATIONSHIP MODEL

Entity relationship (ER) model is a most popular tool for data modeling.

Through ER model high level conceptual database design is performed.ERdiagram can express the overall logical structure of a database

graphically.ER diagrams are simple and clear-qualities that may well account

in large part of the widespread use of the ER-model. Such a diagram consists

of the following major components:

Rectangle, which represents entity sets.

Ellipse, whichrepresent attributes.

Diamonds, which represents relationship sets.Lines, whichs links attributes to entity sets and entity sets to relationship

sets.

Double ellipses, which represents multivalued attributes.

Dashes ellipses, which denote derived attributes.

Double lines, which includes total participation of an entity in a relationship

set.

Double rectangle, which represent weak entity sets.

ENTITY

An entity is a thing or object inthe real world that is distinguishable from

all other objects. For example, each person in the enterprise is an entity. An

entity has set of properties, and the values for some set of properties may

uniquely identify an entity.

ENTITY SETS

An entity set is a set of entities of the same type that share the same

properties, or an attributes. The set of all people who are customer at a given

bank, for example, can be defined as entity set customer.

23

ATTRIBUTES

An attribute is a property of an entity. Each entity may have many attributes.

A particular entity will have a value for each of its attributes. The attributes

values that describes each entity become a major part of the data stored inthe database.

Attributes can be of following types:

Simple

Composite

Single-Valued

Multivalued

Stored

Derived

ABOUT DFD

A data-flow diagram (DFD) is a graphical representation of the "flow" of

data through an information system. DFDs can also be used for the

visualization of data processing (structured design).

On a DFD, data items flow from an external data source or an internal

data store to an internal data store or an external data sink, via an

internal process.

INTRODUCTION

Testing is a process of executing a program with the intent of finding an

error. Testing is a crucial element of software quality assurance andpresents ultimate review of specification, design and coding.

System Testing is an important phase. Testing represents an interesting

anomaly for the software. Thus a series of testing are performed for the

proposed system before the system is ready for user acceptance testing.

A good test case is one that has a high probability of finding an as

undiscovered error. A successful test is one that uncovers an as

undiscovered error.

TESTING OBJECTIVES

1. Testing is a process of executing a program with the intent of finding

an error.

2. A good test case is one that has a probability of finding an as yet

undiscovered error.

3. A successful test is one that uncovers an undiscovered error.

OBJECTIVE

The primary objective for test case design is to derive a set of tests that

has the highest livelihood for uncovering defects in software. To

accomplish this objective two different categories of test case design

techniques are used. They are as follows:-

White box testing.

Black box testing.

WHITE-BOX TESTING

White box testing focus on the program control structure. Test cases are

derived to ensure that all statements in the program have been executed

at least once during testing and that all logical conditions have been

executed.

BLACK-BOX TESTING

Black box testing is designed to validate functional requirements without

regard to the internal workings of a program. Black box testing mainly

focuses on the information domain of the software, deriving test cases

by partitioning input and output in a manner that provides through test

coverage. Incorrect and missing functions, interface errors, errors in data

structures, error in functional logic are the errors falling in this category.

TESTING STRATEGIES

A strategy for software testing must accommodate low-level tests that

are necessary to verify that all small source code segments has been

correctly implemented as well as high-level tests that validate major

system functions against customer requirements.

TESTING FUNDAMENTALS

Testing is a process of executing program with the intent of finding

error. A good test case is one that has high probability of finding an

undiscovered error. If testing is conducted successfully it uncovers the

errors in the software. Testing cannot show the absence of defects, it

can only show that software defects present.

UNIT TESTING

Unit testing is essential for the verification of the code produced during

the coding phase and hence the goal is to test the internal logic of the

modules. Using the detailed design description as a guide, important

paths are tested to uncover errors within the boundary of the modules.

These tests were carried out during the programming stage itself.

INTEGRATION TESTING

Integration testing focuses on unit tested modules and build the

program structure that is dictated by the design phase.

SYSTEM TESTING:

System testing tests the integration of each module in the system. It

also tests to find discrepancies between the system and its original

objective, current specification and system documentation.The primary

concern is the compatibility of individual modules. Entire system is

working properly or not will be tested here, and specified path ODBC

connection will correct or not, and giving output or not are tested here

these verifications and validations are done by giving input values to

the system and by comparing with expected output. Top-down testing

is implementing here.

ACCEPTANCE TESTING:

This testing is done to verify the readiness of the system for the

implementation. Acceptance testing begins when the system is complete.

Its purpose is to provide the end user with the confidence that the system

is ready for use. It involves planning and execution of functional tests,

performance tests and stress tests in order to demonstrate that the

implemented system satisfies its requirements.

INNOVATIVENESS USEFULNESS

The application is feasible for the economic as well as the technical advantages it

gives.

The main advantages of this project are described in details as follows:-

This particular project is a solution developed to communicate between the users

across worldwide through Internet. The concept of sending letters and telegraphs

has been reduced due to the new era of Internet Mailing. One such facility is being

provided by the Chat Server. A message or information can be sent via many

Medias, such as it can be telephonic, telegrams, fax etc to the recipient. Each such

information requires a high level of security. To maintain such security and smooth

completion of any communication it requires more time and human effort in

manual systems. This project has been developed to receive instant formatted test

and graphical messages and to provide total user satisfaction

Future Scope

We will definitely try to add some new lineaments over the coming

months so that it fulfill our every need and gives the users the best chat

experience.

We are planning to include video chat option.

We have an idea to come up with features like the wall, picture

navigation and how messages be shown in inbox.

LIMITATION

In this project there are some limitations which can be dissolved if we

get more time:

1. Due to shortage of time-span, we were unable to add the video-chat

feature.

2. The desired look and feel are not up to the benchmark, there is a need

to focus on visual aspects.

3. We will be looking at a new way to show when you have a new

message or friend request.

4. The purpose of this project is to guide and facilitate more and more

online users. So, the site should be very well backed up and it is very

necessary to have an close eye as far as security measures are concerned

i.e, these need to be updated more often than not.

Conclusion

Since its inception, the internet has become a more and more relied

upon medium in peoples' everyday lives.People love to get engaged in

communication via real-time conversation. In an on-the-go society, the

role of online chatting system is very appealing and beneficial.

Our project is only a humble venture to bring back the personal touch at

the time of social interaction. Several user friendly coding have also

adopted. It is easy to use and the installation technique is so simple that

will have you up and running in minutes.

Although, we have tried our level best to make this error-free and

enjoyable to the users, there are still ways to improve. We are trying to

implement some innovative thoughts, several bugs and glitches have

been fixed while doing this. But, things do not happen overnight, as they

say,the sky's the limit, development must roll on.
