Online social networking is quite popularand websites are generally used for this purpose. In factsocial networking websites function like an online communitysharing common interests like hobbies, religion, politics andeven business.

Once you have access to Net4U you can use it for youroverall development. Right from making friends todiscussing about wide variety of topics Net4U apt for everyoccasion.

Upon becoming a part of Net4U, you can create your owncircle of friends and ignore members who do not share

anything in common with you.

In future it will provide the opportunity to its members tosort themselves into smaller groups based on their special

interests. This will result into development of fan clubs andnet meetings to different age groups. It might be quitesurprising to note that Net4U have been designed for helpingIndian singles to find friends and dates.

In this software information is handled by using MS SQL 2005for storing records in a database, as backend. For frontend

java J2EE (Jdk 1.6), IDE Eclipse / MyEclipse is used. HTML isused as hypertext markup language and java script is usedas a scripting language.

Project is categorized in a web based system, which

has all feasible

features of a social networking s ite and a hub of

knowledge in about all fields.

The approach of application testing adopts the basic principle for all

software testing and applies a strategy and tactics that have been

recommended for object oriented system .the following steps summarizes

the approach:

1. The content model for the web application is reviewed to

uncover errors.

This is like copy-editing.

22


23/26

2. The design model for the web application as reviewed to

uncover Navigation error.

Use cases derived as part of the analyst activity, allow a web

Engineer exercise each usage scenario against the architectural

and navigational design. These non-executable test help

uncover error in navigation.

3. Selected processing component and web page is unit tested.

When web apps are considered, the concepts of the unit

changes, each web page encapsulated in itself content

navigation link as well as script, form and applet (processing

element). It is not always possible or practical to test each of

these characteristic individually.

3. The architecture is constructed and integration tests are

conducted.The strategy for integration testing depends upon the

architecture that has been chosen for the web application.

4. The assembled web application is tested for overall functionality

and content delivery.

Like conventional validation, the validation of web based

systems and application focuses on user visible action and user

recognizable output from the system. To assist in the derivation

of validation tests the tester should draw upon use cases the

use cases provides a scenario that has high likelihood of

23


24/26

uncovering errors in user interaction requirement.

For the system security we can take the following step which is

as follows:-

Valid username and passwords given by the administrativecontrol.

Provide different kinds of access requirements for differentpeople.

Password stored in the database is in the encrypted form.

Password in case sensitive.

Session or Cookies

Net4U application can be extended in various ways for providing

better means of communication.

Since this system has been generated by using ObjectOriented programming, there are every chances of reusability of the

codes in other environment even in different platforms. Also its

present features can be enhanced by some simple modification in the

codes so as to reuse it in the changing scenario.

24


25/26

Reusability is possible as and when we require in this application.

We can add new features as and when we require.

For example :

In future this web application can be extended to make groups thatshare common interests.

In future we can provide the facility to upload live video and musicvideo also .

We can introduce video conferencingto make the coomunicationmore real and effective.

Forum and blog creation can also be implemented to extend thescope.
