Chapter 1 Introduction

1.1 Title of the Project is Social Networking Website

1.2 What is a social networking website?

As the name suggest, it is a web application based on the popular

concept of online socializing that focuses on facilitating the building of social

relations among people who share interests, thoughts, activities,

backgrounds, or real-life connections. This social networking application is

designed to make social life more active and stimulating. It can help us to

maintain existing relationships with people and share our thoughts, pictures

and messages, and establish new ones by reaching out to people we have

never met before.

In this era of chaos and war, it is vital for any society to maintain

a high level of social etiquette. While people have always socially networked

with one another, this web application will do the same in a global manner.

1.3 Why is the particular topic chosen?

The lifestyle of every living being all around the world has

been changed in this era of globalization. The social interaction among

people also improved in a global way as the advancements of

communication technology. The word online is a very popular word now-

a-days. So, I have chosen this topic as it is going to give me a lifetime

experience of studying and developing a fully fledged Web-based

Application as per todays trends.

1.4 Overview of the project

Page |2


3/89

In this system there is a registration process for the users

who intends to join the online social network. After the success of the

registration process the user has to login to the system to search his/her

friends, relatives, near and dear ones and can make friends by sending

friend request. If the request is accepted, then a user can share his/her

personal thoughts, interest, create groups, upload photos etc. So, it is a

system of building social relation over the internet through a web-based

application or online service.

Chapter 2 Objectives

Every developed system has some predefined objectives. The

project work entitled social networking website has the following main

objectives:

1. To provide an attractive and flexible interface to an end user to make

friends online, create groups and events.

2. To help an end user to share his thoughts, ideas and pictures.

3. To help find people on similar interest to share Group events

organized by a particular group.

4. To help him to celebrate a social occasion online, by wishing their

beloveds on the special day.

5. To help organize and find people over the web.

6. The web application will also endow the webmaster of creating a

directory of people and organizing it.

Chapter 4 Preliminary investigation andFeasibility Study

4.1 The existing system

People built society to interact with each other as they cannot

live alone. Socialization is the process formed by mankind to live with one

another, to share their thoughts, interest, knowledge and many more. For that

reason people build some social institution such as social club, park etc. For

a distant one, people use other communication method such as postal,

telephone, mobile etc. to interact with one another.

4.2 The proposed system

With the advancement of technology the process of

socialization has been improved. The globalization makes the distance among

people very short. People prefer internet technology to communicate with each

other as it is reliable and quick and also cost effective. So, the proposed

system entitled social networking website is web-based communication

system over internet which is reliable and cost effective than the conventional

way of communication.

Page |6


7/89

4.3 Feasibility study

Before planning the steps for analyzing an existing system and

designing a new one, we have to consider the pros and cons of developing the

project i.e. the cost effectiveness and other aspects.

Feasibility analysis is carried out to ensure the fact of whether the

development of a new system will be cost effective and profitable or not.

Types of feasibility analysis

The feasibility study or feasibility analysis is carried out three

different angles i.e. there are 3 directions for doing feasibility study or

analysis.

These are

1.Economic feasibility study,

2.Technical feasibility study and

3.Operational feasibility study.

4.4 ECONOMIC FEASIBILTY STUDY

Economic feasibility study is defined as the study and

analysis of the facts by which we can determine as to whether the new

system which is to be developed is really economically possible to

develop or not. The project work entitled social networking website is

Page |7


8/89

economically feasible. It reduces the cost of conventional

communication such as postal system, telephone, mobile etc., as this

web-based application only require an internet communication which is

now-a-days very affordable. The following analytical information may be

useful for revealing the aforesaid economic feasibility of the proposed

system.

[Cost benefit analysis]

4.4.1The conventional way vs. the proposed system for building social

relation:

There are various way of building social interaction among

people. Some examples of them are as follows:

The conventional postal system.

The telephone/mobile system.

Social club formation etc.

These conventional methods offer a common way to the

people to socially interact with one another. For example postal system

provides a way to sent and receives letters from a distance place. But it is

not very reliable and also not cost effective. The telephone and mobile

system also provides the same with more reliability but I think it is also

not cost effectiveness. The formation of social club need a well defined

place and it is not for the people from distance places.

Page |8


9/89

So, after observing the conventional method, I think that this

online application provides a cheap way to online socialization. It will only

cost for the internet connection and a personal computer/laptop/smart

phone, which I think is a common thing now-a-days. There is no extra cost

of using this application. Only the user has to pay for the internet

connection only.

Here is rough comparison between a conventional way, in this

case I take the example of a social club and the proposed system:

Requirements for a Social club:

A rented house or room which will cost at minimum Rs. 4000 per

month.

Electricity bills which will cost at minimum Rs. 500 per month.

Furniture which will cost approximately Rs. 20000 at minimum.

Weekly maintenance such as cleaning will cost Rs. 500 per month.

Other expenses such organizing parties etc. will cost Rs. 1000 per

month.

So if calculate average expenses per month excluding

furniture cost we will get as follows:

Rs. (4000+500+500+1000) = Rs. 6000 per month

Now I am going to compare the average monthly cost of using

the proposed system as follows:

Page |9


10/89

The proposed system requires:

A personal computer which will cost Rs. 20000 at minimum

An internet connection which will cost Rs. 1000 at minimum per month

If exclude the personal computer the average monthly cost

will be only Rs. 1000.

So the differences between the two systems can be shown in a bar chart as

follows:

After observing the above statistics it can be concluded that the

proposed system is economically feasible.

4.3 TECHNICAL FEASIBILTY STUDY

Page |10


11/89

Technical feasibility study as the study where we analyze whether

using the currently available technology and tools, it is possible to develop

the said project or not. This web-based has been developed using the

currently available tools such as PHP (server side), JavaScript/JQuery

(client side), html at front end and MySQL as backend. All the aforesaid

tools are currently available. The system is compatible with any type of

personal computer, handheld device such as smart phone with currently

available operating system. So I think the project work is technically

feasible.

4.4OPERATIONAL FEASIBILTY STUDY

Operational feasibility study as the study of whether, the project

to be developed will be an operational feasible one or not. This means that,

we have to carefully judge whether the system which will be developed i.e.

the new system will be operable or not by the intended user(s). This project

work is operationally feasible because of its user-friendliness and ease of

use. Users will find comfort using this web-based application as it provides

more facility and fun than the conventional communication method.

Page |11


12/89

4.5 CONCLUSION

We can thus see that the new system is a feasible one from all

the three angles or sides i.e. economical, technical and operational sides.

Hence, I can safely state that the new system is feasible one and

this carries us to the next phase of development of the said project work.

Chapter 5 System Analysis

The analysis phase is the detailed understanding of all the

important facts for making understandable software under investigation. The

initial investigation of a particular system is that one should know the

requirements, process involved in the system. It is the process of studying the

business processors and procedures, generally referred to as business

systems, to see how they can operate and whether improvement is needed.

5.2 System planning

INTRODUCTION

While doing system analysis and design, we have to carefully make

an estimated plan which includes the tentative duration that will be required

for giving completion to the various projects activities. This helps in

controlling the schedule of the project.

While doing a software project I try to implement software

planning particularly. Software planning basically means drawing up

schedules, time tables, activity networks, etc. to do various project activities

while developing the project.

There are various planning tools available for scheduling the

project activities. Some of the popular tools are:

1.The PERT diagram and

2.Gantt chart.

Page |29


30/89

While, the Gantt chart depicts the various project activities and

their estimated duration, it does not show the precedence, that is, the relative

sequence between the activities. So, if we also want to express the precedence

relationship between the various projects activities then the Gantt chart is not

a suitable option.

The pert diagram overcomes the difficulty I have stated in case of the Gantt

chart.

THE PERT DIAGRAM:

The pert diagram is also known as program evaluation and

review technique. In this technique, I use certain graphical symbols connected

together in the form of a directed weighted graph.

The symbols used in the pert diagram are-

- The arrow represents a task

- The circle represents the 'beginning or completion

of task.

Page |30


31/89

In planning the activities if this project works, I have used the PERT diagram

shown below.

0 20 20 60 60 90 90 110

Fig 1: The PERT Diagram

In the above given PERT diagram I have estimated the duration of various

activities as follows:

1.I start with System Analysis on day 0 and plan to finish it in 20 days.

2.System Design is supposed to begin next and is estimated to be

completed within 40 days.

Page |31


32/89

3.Thirdly, I start testing and debugging and estimated its duration as 30

days.

4.At last, the task of implementation is supposed to see an interval of 20

days.

Thus, I estimated the total no. of days to completed the state tasks to be

20 + 40 + 30 + 20 days= 110 days

GANTT CHART:

Gantt chart shows project activities and the amount of time

they will take. This activity scheduling method was first introduced in 1914 by

Henry L. Gantt as a rudimentary aid to plot individual tasks against time. The

Gantt chart uses horizontal bars to show the durations of actions or tasks.

The left end marks the beginning of the tasks; the right ends its finish. Earlier

tasks appear left and later ones in the lower right.

Gantt chart, in case, is given below.

5.5 Data Dictionary

A data dictionary is a structured repository of data about data.

A data dictionary has many advantages. The most obvious is documentation;

it is valuable reference in any organization. Another advantage is improving

analyst/user communication by establishing consistent definition of various

elements, terms and procedures. During implementation, it serves as a

common base against which programmers who are working on the system

compare data description. Also control information maintained for each data

element is cross referenced in the data dictionary. E.g. program that use a

Page |40


41/89

given data element are cross referenced in a data dictionary, which makes it

easy to identify them and make any necessary changes. Finally, a data

dictionary is an important step in building a database.

Chapter 6 SYSTEM DESIGN

6.1 Introduction

System design is the process of developing specifications for a

candidate system that meet the criteria established in the system analysis.

Major steps in system design are defining architecture, components, interfaces

and other characteristics, the preparation of the input forms and the output

reports in a form applicable to the user.

System design is the creative act of invention, developing new

inputs, a database, offline files, procedures and output for processing

business to meet an organization objective. System design builds information

gathered during the system analysis.

Page |45


46/89

6.2 Characteristics of a well defined system

In design an efficient and effective system is of great importance

to consider the human factor and equipment that these will require to use.

System analyst must evaluate the capabilities and limitations of the personal

and corresponding factors of the equipment itself.

The characteristics associated with effective system operations are:

Accessibility

Decision Making Ability

Economy

Flexibility

Reliability

Simplicity

6.3 Modularization details

Modularity is achieved by dividing the whole system into uniquely

named and addressable components known as modules. A complex system is

partitioned into a set of discrete modules in such a way that each module can

be developed independent of other modules. After developing the modules,

Page |46


47/89

they are integrated to meet software requirements. It helps to plan the

development in a more effective manner, accommodate change easily, conduct

testing and debugging effectively and efficiently and conduct maintenance

work without adversely affecting the functioning of the software.

The system social networking website is divided into modules

which are described as follows:

User registration module: this module provides a user to create his/her

account so that the user can access the system. The user has to provide

information about his/her username, email account and Password. Then the

module send a confirmation email to his email account where the user has

been verified make him/her part of the system as a valid user.

Login module: this module provides the first level of security to a user to

access the system against username and password.

Update profile:it provides a user to change or update his/her profile details.

Search friends:it provides a user to search for existing friends in the system.

Friend list:this module tracks who is a friend with whom. It searches for the

database and finds the friends of a logged in user.

Send friend request:this module is used to send friend request to an existing

user of this system.

Page |47


48/89

Accept friend request:this module offers a user to accept an incoming friend

request.

Create groups:it provides a user the facility to create groups to share

thoughts with other member of this system with similar interest.

Add group member:this module is used to add member to a particular

group.

Create photo albums and upload photo:it provides a user to create new

photo albumsand upload or share photos among his friends.

Post message on wall:this module is used by a user to post or share his/her

thoughts as a form of message in the wall page.

Commenting on post:this module provides a user the facility to cross-

comment on each other post.

Expression on post:it is used to give various expressions such as smiles,

wink, and laugh on each other post.

Suspend user:this module is used by the administrator to suspend a user

with a malicious activity.

6.4 Database Design

Page |48


49/89

The overall objective in the development of the database

technology has been to treat data as an organizational resource and as an

integrated whole. Database management system allows data to be protected

and organize separately from other resources. Database is an integrated

collection of data. The most significant of data as seen by the programs and

data as stored on the direct storage access storage devices. This is the

difference between logical and physical data. The organization of data in the

database aims to achieve free major objectives:

Data Integration

Data Integrity

Data Independence

The databases are implemented using a DBMS package. Each

particular DBMS has unique characteristics and general techniques for

Database Design.

The proposed System stores the information relevant for

processing in the MySQL database. This MySQL database contains tables,

where each table is called a field or column. A table also contains records

which is a set of fields. All records, in a table the same set of fields with

Page |49


50/89

different information. Each table contains key fields that establish

relationships in a MySQL database and how the records are stored. There are

primary key fields that uniquely identify a record in a table. There are also

fields that contain the primary key from another table called foreign keys.

It is a known fact that the program cannot be written until the

data are defined, so the database must be defined. The starting point for this

process is data dictionary. The records data structures and elements to be

stored in each database are identified and extracted. Next the analyst codes

the source statements library. Eventually, the programmer will incorporate

the source code into the various programs, thus assuring consistency and

simplifying the coding process. The databases have been designed in such a

way that there is no duplication of information and loss of information.

The database of the proposed system comprises 18 tables

normalized to 2NF.

Page |50


51/89

6.5 schema design

In database design, several views of data must be considered

along with the persons who use them. In addition to data structuring, where

relationships are reflected between and within entities, we need to identify the

application programs logical views of data within an overall logical data

structure. The logical view is what the data look like, regardless of how they

are stored. The physical view is the way data exist in physical storage. It deals

with the data are stored, accessed, or related to other data in storage.

The schema is the view that helps the DBMS decide in storage act

upon as requested by the application program.

6.6 Relational model:

Certain rules followed in creating and relating databases in the

relational databases. This governs how to relate data and prevent redundancy

of the data in the databases. The first set of rules called relational rules

ensures that the database is a relational database. The second set called the

Page |51


52/89

normalization rules simplifies the database and reduce the redundancy of the

data.

Proposed system this relational database rules are applied to

reduce the redundancy make future changes to the table structure easier to

and minimize the impact of these changes on users interface to the database.

This is done first determining what information is needed, how items are

related, what constraints are established. Tables are created and linked by

appropriate key fields. The constraints on the data are used to guide the

building of tables. The tables are created by making use of the normalization

principles. The proposed system has its own tables in the second normal

form.

6.8 User interface design

User interface is the link between a system and the user. Without

a proper user interface a user finds lots of trouble accessing the system which

may be defined as the major drawback of the system. User interface provides

a user to enter his required data as input and see the result as the output. An

easy to use interface is always preferable by a user. Most of todays interfaces

are graphical in nature as it provides a user a very comfortable interface to

Page |61


62/89

access the system. The project work entitled social networking website is

based on Graphical User Interface which very easy to use and comfortable as

it provide validation and verification of input data. Here are some screenshots

which will describe the easiness of the user interface of the system.

Chapter 7 Testing

Software testing determines the correctness, completeness

and quality of the software being developed. It is closely related to the terms

verification and validation. Verification refers to the process of ensuring that

the software is developed according to its specifications and validation refers

to the process of checking that the developed software meets the requirements

specified by the user.

7.1 Objectives of testing

First of all objectives should be clear.

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

errors.

To perform testing, test cases are designed. A test case is a particular

made up of artificial situation upon which a program is exposed so as to

find errors. So a good test case is one that finds undiscovered errors.

If testing is done properly, it uncovers errors and after fixing those

errors we have software that is being developed according to

specifications.

Page |66


67/89

7.2 Testing principles

Before applying methods to design effective test cases, software

engineer must understand the basic principles that guide the software testing

process. Some of the most commonly followed principles are:

All test should be traceable to customer requirements as the

objective of testing is to uncover errors, it follows that the most severe defects

(from the customers point of view) are those that causes the program to fail to

meet its requirements.

Tests should be planned long before the testing begins. Test

planning can begin as soon as the requirement model is complete. Detailed

definition of test cases can begin as soon as the design model has been

consolidated. Therefore, all tests can be planned and designed before any code

can be generated.

7.3 Test case design

Page |67


68/89

A test case provides the description of inputs and their expected

output to observe whether the software or a part of the software is working

properly. Generally a test case is associated with details like identifier, name,

purpose, required inputs, test conditions and expected outputs.

Page |68


69/89

7.4 Unit Testing:

Unit testing was conducted first. Different modules of the

software were tested against the specifications produced during design of the

modules. Verification of the code produced during the coding phase was

done. Each module was tested separately.

Unit testing focuses verification effort on the smallest unit of

software design module. This uncovers errors within the boundary of a

module. Unit testing is actually White box testing both the external things as

well as the internal codes are tested. In testing, the interfaces are tested in

order to ensure the proper flow of data in and out of the module. The

boundary testing is done to ensure that the module keeps the limit of it. All

independent paths are tested to ensure that all statements are tested at least

once. At last the error path is also tested.

7.4.1 Unit testing report

To perform unit testing we have taken a simple unit of the system

which is used to validate email of a particular user. As input, we have passed

variables i.e., an email of a user through URL to the processing PHP script

Page |69


70/89

named verifyUserEmail.php. The PHP script will give output 1 if the given

email is correct and give output 0 if it is not.

Here is the screenshot of the input-

The screenshot of the output is as follows:

Page |70


71/89

So, the unit testing is successful on that particular unit. I

assume that it will happen for the all smallest unit of the system.

7.5 Integration Testing

One of the most difficult aspects of software development is the

integration and testing of large untested subsystems. The integrated system

frequently fails in significant and mysterious ways and its difficult to fix it.

Integration testing exercises several units that have been

combined to form a module, subsystem or system. Integration testing focuses

on the interfaces between units, to make sure the units work together. The

nature of this phase is certainly white box, as we must have knowledge of the

units to recognize if we have been successful in focusing them together in the

module.

7.5.1 Integration testing report

I have used the user login module to perform integration testing

in this system. The user login module provides a user to access the system

with the correct user credentials. This module also validates the input

provided by a user whether it is blank or not. If the input is blank it will show

a message directing the user to fill the required input to login to the system.

Page |71


72/89

For example if a user enter his username but forgot to enter the

password the follow will happen. The JavaScript, which validate the user

input, finds absence of required data will show an alert message and then

redirecting the user to fill the specified field. Here is a screen shot of the above

said example.

So the test is done by providing input through the URL to the

processing PHP script. If the PHP script, after processing gives output 1 then

I assumes that integration testing is successful with no JavaScript prompt

Page |72


73/89

error message else if it outputs 0 there must be some error in the code in

the module.

Here is the screenshot of the input-

The screenshot of the output is as follows:

Page |73


74/89

So, the integration testing is successful on that particular

module. I assume that it will happen for the all module of the system.

7.6 System Testing

Page |74


75/89

Then system testing was conducted. Here the entire software

system was tested. The reference document used for this process was

requirement document and the goal was to see if the software meets its

requirements.

System testing includes the thorough testing of the product.

System testing is actually a series of different tests whose primary purpose is

to fully exercise the computer based system. The tests are recovery testing:

this checks the recovery of the system when failure occurs. This is to ensure

that there are recovery procedures for error occurrences.

7.6.1 System testing report

The system has passed the system testing as the whole system

work correctly according to its input and produces the desired outputs

required by the user of the system. Every unit, module has worked correctly

to make the whole system reliable and error free.

Chapter 9 Implementation of Security for the Software developed

System security is a vital aspect when it comes to developing

a system. The system should ensure the facility of preventing unauthorized

personnel from accessing the information and the data within the system.

The system should provide total protection for each users information so

that the integrity of the data is sustained.

The proposed system ensures the security and the integrity

of data. This is done by providing a password login system for each

authorized user. The password is stored in encrypted form usingMD5

encryptionin the database. At the starting of the application, the user is

asked for username and password and only the correct information allows

further navigation in the project. However, the System Administrator has

access to all kinds of information.

Page |84


85/89

Chapter 10 User manual

10.1 How the system works?

The application will be accessed at two basic levels of

authorization. One will be the administrator of the web application and the

other will be the average user who will follow a special procedure to register

himself at the website, then verify his email id and finally start maintaining

and using his account. After accessing the system with the username and

password the user can do the various activities like search friends, post a

message on the wall, upload photo and other contents etc.

10.2 Creating an account

To create an account the user has to register himself by filling up

the sign up form on the home page and click on the submit button. It will

mail an activation link to his respective email. So he has to click on the

activation link to make him a valid user on the system.

10.3 Edit Profile Info

To edit profile, first a user has to log in to the system. After log in

he has to click on the edit profile link on the user home page. Next, he has to

enter his info one by one and then click save button.

10.4 Search friend and send request

Page |85


86/89

On the user home page, at the top there is a textbox where a user

can type his friends name to search and hit enter keys. If the friend exist he

can send a friend request by clicking on add as a friend.

Chapter 11 Conclusion

The system has been developed for the given condition and is

found working effectively. The developed system is flexible and changes

whenever can be made easy. The software has been developed in a neat and

simple manner, thereby reducing the operators work.

The speed and accuracy are maintained in proper way. The user

friendly nature of this software makes comfortable for any type of user with a

little knowledge of computer and the internet. The results obtained were fully

satisfactory from the user point of view.

The system was verified with valid as well as invalid data in each

manner. The system is run with an insight into the necessary modifications

that may require in the future. Hence the system can be maintained

successfully without much network.

Chapter 12 Limitation of the Project

Every developed system has some limitation in concern to the

tools and environment it uses. The limitation of the project is as follows:

1. Absence of Multimedia Blog site for the users which requires a huge

amount of storage space.

2. Absence of Video Uploading and chatting facility for the users.

Chapter 13 Future Scope and Further Enhancement of the project

. As the web application is a module based, so we can do the

changes very easily and integrate new modules very efficiently and with ease.

The application is developed in such a way that any further enhancements

can be done with ease. Some effective actions can be taken to enlarge the

scope of the project and to enhance it. Some of them are given below:

1. In future we can design more interactive pages in the website which

will provide a user to upload and share more information as well as act

as a more reliable and secure system.

2. Video Uploading, Chatting and Multimedia Blog Site can be extra

options in the project which can be provided to the users in future.
