PREFACE

The present miraculous in the fields of technology and theresulting impact on almost all work of life can be attributed to the fastdevelopment of computer technology. The growth of technologyparticularly in the recent has been very fast.

In today's fast changing environment, computer can withproper programming process data towards logical conclusion classifyand makes them readily available for the use. Computers are seenreplacing human work. Use of computers can be seen in the offices,hospitals, railways and airline reservations, hotels, department storesetc.

Computers have not allowed the enhancement in

computation speed but also have brought about considerablereduction in space with cost effectiveness. Computers have become soversatile, that they have become indispensable not only to engineers,scientists, business executive, managers administrators, but also tothe common men. This era of information explosion is totally basedupon computer technology, which is accepted world wide todaypractically each and everything is access by computer (Internet).

It used to be that computers made a difference only tolives of those used them. But with microprocessors being embedded ineverything, from washing machine to toys and automobiles, they aregoing to impacting a lot more lives.

With the explosion of information technology and advertnew electronic and computers devices users need to be acquaintedwith a lost of things relating to myriad branches of knowledge andskills and numerous aspect of social, economy political and technologysystem to achieve the goal of nations growth and development in the21st century.

About The Project:-

Introduction:-

Online or virtual Social Network, allow people with commoninterests to meet, communicate and share ideas andinformation, through a network like the web. While doingthis, participants develop bonds with each other and the


3/53

community as a whole. Online Social Network have emergedas one of the most potential levers of action the web. SuchSocial Network can be built around demographic groups -students, parents, professional groups - doctors or

programmers or who share a particular personal interest -bikers or clock repairers.

Threaded by a common interest, community participantshave a lot to share with each other. Once established, onlineSocial Network provides a new way for brands to reachcustomers with special interest in their products. OnlineSocial Network aims to achieve the following:

Engage citizens in participating democracy, discuss

their own issues etc.

Encourage citizen-source journalism that complementsand in some cases competes with local for-profit newsorganizations

Enable government officials to communicate withconstituents more often, more easily and in a moremeaningful way

The target audience is anyone interested in local communityissues/ any other issues.

How does online Social Network Interact?

Online Social Network interacts by virtue of their sharedpassion. They can be found in a variety of web destinationsoffering expression to interest-related activities. Likediscussion forums, book sites, auction sites,

trading/exchange sites, blogs and so on. The tools used aregenerally message boards, blogging applications, text chat.

The building blocks of an online community


4/53

Online virtual Social Network makes use of a range oftechnologies that support person-to-person and person-to-group communications. The enabling technologies facilitatetwo distinct types of communication:

Real time (or synchronous) Communication: through textchat and instant messaging

Non-real time (or asynchronous) Communication: throughmessage boards, mail lists, member and community webpages, and surveys.

Additionally virtual Social Network also depend on a member

database and may also include technologies to support

registration, electronic commerce, directories (of products,services, suppliers, etc.) and searches (for searching

member profiles, community documentation, reports,

articles, transcripts, archives,etc.).

System Overview

THEORETICAL BACKGROUND

SYSTEM ANALYSIS AND DESIGN

ANALYSIS:


7/53

Requirement analysis is down in order to understand

the problem the software system is to solve. The problem

could be automating an existing manual process, developing

a new automated system, or a combination of the two. For

large systems that have many features, and that need toperform many different tasks, understating the requirements

of the system is the major task. The emphasis in the

requirements analysis is on identifying what is needed from

the system, not how the system will achieve its goals. The

developer has to develop the system to satisfy the clients

needs.

Once the problem is analyzed and the

essentials understood, the requirement must be satisfied in

the requirement specification document. For requirement

specification in the form of a document, some specification

language has to be selected. All the factors that may affect

the design and the proper functioning of the system should

be specified in the requirement document. Preliminary user

manual

That describes the entire major user interfacesfrequently forms a part bof the requirements documents.

DESIGN:

The purpose of the design phase is to plan a solution of

the problem specified by the requirement document. This

phase is the first step in moving fro the problem domain to

the solution domain. Stating with what is needed; design

takes us towards how to satisfy the needs. The designsaffect the quality of software; it has major impact on the

later phases, particularly testing and maintenances. The

output of this phase is the design document.

This document is similar to a blue print or

as plan fort the solution and is used later during


8/53

implementation, testing and maintenance. The design

activity is often divided into two separate phases system

design And detailed design, which is some time also called

top level design, aims to identify the modules should be in

the system, the specifications of these modules, and howthe they interact with each other to produce the desired

results.

At the and of the system design all the major data

structures, file formats, output formats and the major

modules in the system and their specifications are decided.

Model-View-Controller Pattern

Model-View-Controller (MVC) is a classic design pattern oftenused by applications that need the ability to maintainmultiple views of the same data. The MVC pattern hinges ona clean separation of objects into one of three categories models for maintaining data, views for displaying all or aportion of the data, and controllers for handling events that

affect the model or view(s).

Because of this separation, multiple views and controllerscan interface with the same model. Even new types of viewsand controllers that never existed before can interface witha model without forcing a change in the model design.

How It Works

The MVC abstraction can be graphically represented as

follows.


9/53

Events typically cause a controller to change a model, orview, or both. Whenever a controller changes a models dataor properties, all dependent views are automaticallyupdated. Similarly, whenever a controller changes a view,for example, by revealing areas that were previously hidden,the view gets data from the underlying model to refreshitself.

A Concrete Example

We explain the MVC pattern with the help of a simple

spinner component which consists of a text field and twoarrow buttons that can be used to increment or decrement anumeric value shown in the text field. We currently do nothave an element type that can directly represent a spinnercomponent, but it easy is to synthesize a spinner usingexisting element types.

The spinners data is held in a model that is shared with thetext field. The text field provides a view of the spinnerscurrent value. Each button in the spinner is an event source

that spawns an action event every time it is clicked. Thebuttons can be hooked up to trampolines that receive actionevents, and route them to an action listener that eventuallyhandles that event. Recall that a trampoline is a predefined

action listener that simply delegates action handling toanother listener.

Depending on the source of the event, the ultimate actionlistener either increments or decrements the value held inthe model The action listener is an example of acontroller.

The trampolines that initially receive the action events firedby the arrow buttons are also controllers however, instead

of modifying the spinners model directly, they delegate thetask to a separate controller (action listener).

Multiple Controllers

The MVC pattern allows any number of controllers to modifythe same model. While we have so far focused only on thetwo arrow buttons as likely source of events, there is, in fact,a third event source in this example Whenever the textfield has focus, hitting the enter key fires off an action event

that may potentially be handled by a different action listenerthan the one handling action events from the buttons.

Some parts of a component may use different controllersthan others

METHADOLOGY USED FOR TESTING

Testing is the process of detecting errors. Testing

performs a very critical role for quality assurance and for

ensuring the reliability of software. The results of testing are

used later on during maintenance also.

LEVEL OF TESTING

In order to uncover the errors present in different phases we

have the concept of levels of testing. The basic levels of

testing are follows:-

System Testing

The philosophy behind testing is to find errors. Test cases

are devised with this in mind. A strategy employed for

system testing is code testing.

Code Testing

This strategy examines the logic of the program. To follow

this method we developed some test data that resulted in

executing every instruction in the program and module i.e.

every path is tested. System is not designed as entire nor

are they tested as single systems. To ensure that the coding

is perfect two types of testing is performed or for that matter

is performed on all system.

Types of Testing

Unit Testing


12/53

Link Testing

Unit Testing

Unit testing focuses verification effort on the

smallest unit of software i.e. the module. Using the

detailed design and the process specification testing is

done to uncover errors within the boundary of the

modules must be successful in the unit test before the

start of the integration testing begins.

In this project each service can be thought of a

module. Giving different set of inputs has tested each

module. When developing the module as well as finishingthe development so that each module works without any

error. The inputs are validated when accepting from the

user.

System Testing

Here the entire software system is tested. The

reference document for this process is the requirement

document, and the goal OS to see if software meets itsrequirements.

Here entire ATM has been tested against

requirements of project and it is checked whether all

requirements of project have been satisfied or not.

Acceptance Testing

Acceptance Test is performed with realistic data ofthe client to demonstrate that the software is working

satisfactorily. Testing here is focused on external behavior

of the system: the internal logic of program is not

emphasized.


13/53

In this project Network Management of Database

System I have collected some data and tested whether

project is working correctly or not.

Test cases should be selected so that largestnumber of attribute of an equivalence class is exercised at

once; the testing phase is an important part of software

development. It is the process of finding errors and

missing operations and also a complete verification to

determine whether the objectives are met and the user

requirements are satisfied.

White Box Testing

This is a unit testing method where a unit will be

taken at a time and tested thoroughly at a statement

level to find the maximum possible errors. I tested step

wise every piece of code, taking care that every

statement in the Code is executed at least once. The

white box testing is also called Glass Box Testing.

I have generated a list of test cases, sample data.

This is used to check all possible combinations of

execution paths though the code at every module level.

Black Box Testing

This testing method considers a module as a single

unit and checks the unit at interface and communication

with other module rather getting into details at statementlevel. Here the module will be treated as a block box that

will take some input and generate output. Output for a

given set of input combination is forwarded to other

modules.


14/53

METHADOLOGY ADOPTED, SYSTEM IMPLEMENTATION

& DETAILS OF HARDWARE & SOFTWARE

System implementation:-

The implementation phase is less creative then

system design. It is primarily concerned with user train, site

preparation and file conversion. When the candidate system

is linked to terminals or remote sites, the telecommunication

network and tests of the network along with the system are

also included under implementation.

During the final testing, user acceptance is tested

followed by user training. Depending on the nature of the

system, extensive user training may be required.

CONCLUSION

Online or virtual Social Network, allow people withcommon interests to meet, communicate and share ideasand information, through a network like the web. Whiledoing this, participants develop bonds with each other andthe community as a whole. Online Social Network haveemerged as one of the most potential levers of action theweb. Such Social Network can be built around demographicgroups - students, parents, professional groups - doctors orprogrammers or who share a particular personal interest -bikers or clock repairers

The system was tested by running it on differentcomputers. The system has a high degree of accuracy and

user friendliness. A few changes were suggested which is tobe incorporated into the system.

The system is a user-friendly system and furtherchanges can be incorporated into the system easily.
