Introduction

Social networking sites allow users to communicate with people, share ideas, activities, events, and interests within their individual networks. Social network sites such as MySpace, Facebook, Orkut, and Google+ have attracted millions of users, many of whom have integrated these sites into their daily practices. There are hundreds of Social Networking Sites, with various technological affordances, supporting a wide range of interests and practices. Sites also vary in the extent to which they incorporate new information and communication tools, such as mobile connectivity, blogging, and photo/video-sharing.

Social Network Sites: A Definition

We define social network sites as web-based services that allow individuals to (1) construct a public or semi-public profile within a bounded system, (2) articulate a list of other users with whom they share a connection, and (3) view and traverse their list of connections and those made by others within the system.

While Social Networking Sites have implemented a wide variety of technical features, their backbone consists of visible profiles that display an articulated list of Friends one who are also users of the system. Each profile in Social Networking has unique ID. After joining an Social Networking Sites, an individual is asked to fill out forms containing a series of questions. The profile is generated using the answers to these questions, which typically include descriptors such as age, location, interests, and an "about me" section. Most sites also encourage users to upload a profile photo. Some sites allow users to enhance their profiles by adding multimedia content or modifying their profile's look and feel. Others, such as Facebook, allow users to add modules ("Applications") that enhance their profile.

Data Flow Diagram

A Data Flow Diagram (DFD) is a graphical representation of

the "flow" of data through an Information System. A data flow

diagram can also be used for the visualization of Data Processing. It is

common practice for a designer to draw a context-level DFD first

which shows the interaction between the system and outside entities.

This context-level DFD is then "exploded" to show more detail of the

system being modeled.

A DFD represents flow of data through a system. Data flow

diagrams are commonly used during problem analysis. It views a

system as a function that transforms the input into desired output. A

(7)

DFD shows movement of data through the different transformations or

processes in the system.

Dataflow diagrams can be used to provide the end user with a

physical idea of where the data they input ultimately has an effect upon

the structure of the whole system from order to dispatch to restock how

any system is developed can be determined through a dataflow

diagram. The appropriate register saved in database and maintained by

appropriate authorities.

ER Diagram:

Entity Relationship Diagrams (ERDs) illustrate the logical structure of databases. An Entity Relationship Diagram is a piece of data-an object or concept about which data is stored.

There are three types of relationships between entities:

● one-to-one (1 to 1): one instance of an entity (A) is associated with one other instance of

another entity (B). For example, in a database of employees, each employee name (A) is associated with only one social security number (B).

● one-to-many (1 to N): one instance of an entity (A) is associated with zero, one or many

instances of another entity (B), but for one instance of entity B there is only one instance of entity A. For example, for a company with all employees working in one building, the building name (A) is associated with many different employees (B), but those employees all share the same singular association with entity A.

● many-to-many (N to N): one instance of an entity (A) is associated with one, zero or

many instances of another entity (B), and one instance of entity B is associated with one, zero or many instances of entity A. For example, for a company in which all of its employees work on multiple projects, each instance of an employee (A) is associated

(11)

with many instances of a project (B), and at the same time, each instance of a project (B) has multiple employees (A) associated with it.

Testing

Introduction

Testing is the process of running a system with the intention of finding errors. Testing enhances the integrity of a system by detecting deviations in design and errors in the system. Testing aims at detecting error-prone areas. This helps in the prevention of errors in a system. Testing also adds value to the product by

conforming to the user requirements.

The main purpose of testing is to detect errors and error-prone areas in a system. Testing must be thorough and well-planned. A partially tested system is as bad as an untested system. And the price of an untested and under-tested system is high.

The implementation is the final and important phase. It involves user-training, system testing in order to ensure successful running of the proposed system. The user tests the system and changes are made according to their needs. The testing involves the testing of the developed system using various kinds of data. While testing, errors are noted and correctness is the mode.

OBJECTIVES OF TESTING:

The objectives of testing are:

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

● A Successful test case is one that uncovers an as- yet-undiscovered error.

System testing is a stage of implementation, which is aimed at ensuring that the system works accurately and efficiently as per the user need, before the live operation commences. As stated before, testing is vital to the success of a system. System testing makes a logical assumption that if all parts of the as system are correct, the goal will be successfully achieved. A series of tests are performed before the system is ready for the user acceptance test.

(14)

TESTING METHODS

System testing is the stage of implementation. This is to check whether the system works accurately and efficiently before live operation commences. Testing is vital to the success of the system. The candidate system is subject to a variety of tests: on line response, volume, stress, recovery, security and usability tests. A series of tests are performed for the proposed system is ready for user acceptance testing.

The Testing Steps are:

●

Unit Testing

Unit testing focuses efforts on the smallest unit of software design. This is known as module testing. The modules are tested separately. The test is carried out during programming stage itself. In this step, each module is found to be working satisfactory as regards to the expected output from the module.

●

_{Integration Testing}

Data can be lost across an interface. One module can have an adverse effect on another, sub functions, when combined, may not be linked in desired manner in major functions. Integration testing is a systematic approach for constructing the program structure, while at the same time conducting test to uncover errors associated within the interface. The objective is to take unit tested modules and builds program structure. All the modules are combined and tested as a whole.

●

Validation

At the culmination of the integration testing, Software is completely assembled as a package. Interfacing errors have been uncovered and corrected and a final series of software test begin in validation testing. Validation testing can be defined in many ways, but a simple definition is that the validation succeeds when

(15)

the software functions in a manner that is expected by the customer. After validation test has been conducted, one of the three possible conditions exists.

a The function or performance characteristics confirm to specification and are accepted.

b A deviation from specification is uncovered and a deficiency lists is created.

c Proposed system under consideration has been tested by using validation test and found to be working satisfactory.

●

Output Testing

After performing the validation testing, the next step is output testing of the proposed system, since no system could be useful if it does not produce the required output in a specific format. The output format on the screen is found to be correct. The format was designed in the system design time according to the user needs. For the hard copy also; the output comes as per the specified requirements by the user. Hence output testing did not result in any correction for the system.

●

_{User Acceptance Testing}

User acceptance of a system is the key factor for the success of any system. The system under consideration is tested for the user acceptance by constantly keeping in touch with the prospective system users at the time of developing and making changes whenever required.

This is done in regard to the following point:

a Input Screen Design

b Output Screen Design

c Format of reports and other outputs.

Security mechanisms

(16)

This system is provided with authentication without which no user can pass. So only the legitimate users are allowed to use the application. If the legitimate users share the authentication information then the system is open to outsiders.

Future Scope and Further Enhancement:

The advantages and disadvantages of a Online Social Networking website are much the same as those for a real life. However, the effort to develop and maintain Oonline Social Networking website is usually far less than that expended for a real life system: The most difficult problem is specifying a virtual machine which can peacefully coexist with the desired target systems. In some respects, this approach makes sense for making people communicate on web. The

identification of clear-cut interfaces is a standard structured programming technique, which (in theory at least) reduces software maintenance costs. The only controversy might be over the particular choice of structure (i.e. social networking). In general, whenever organizational site is likely to outlive its hardware, the ONLINE SOCIALNETWORKING approach warrants

consideration. This is because of the high redevelopment costs.

Now, when such social networking site is easily approachable to the user via website, it is easy and convenient for them to be in touch with their colleagues. It gives further opportunity to the coming users to enhance the IT technologies.
