Online Social Network Introduction:
Online or virtual Social Network, allow people with common interests to meet, communicate and share ideas and information, through a network like the web. While doing this, participants develop bonds with each other and the community as a whole. Online Social Network have emerged as one of the most potential levers of action the web. Such Social 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 participants have a lot to share with each other. Once established, online Social Network provides a new way for brands to reach customers with special interest in their products. Online Social Network aims to achieve the following: •
•
Engage citizens in participating democracy, discuss their own issues etc. Encourage citizen-source journalism that complements and in some cases competes with local for profit news organizations
•
Enable government more meaningful wayofficials to communicate with constituents more often, more easily and in a The target audience is anyone interested in local community issues/ any other issues. How do online Social Network interact Online Social Network interact by virtue of their shared passion. They can be found in a variety of web destinations offering expression to interest-related activities. Like discussion forums, book sites, auction sites, trading/exchange sites, blogs and so on. The tools used are generally message boards, blogging applications, text chat.

Very comprehensive user and usage statistics
Overall description The Online Social Network encompasses numerous files and information from the User Database, as well as files on the server system. This system will be completely web-based, linking to User Data Base and the remote web server from a standard web browser. An Internet connection or as LAN connection is necessary to access the system.
System environment
Figure 1: System Design The Online Community Blogging Blogging web site will be operated from the web server. When an Admin connects to the Web Server, the Web Server will pass the inform,ation to the database server . The Web Server will then interact with the Database through BDE, which allows the Windows type program to transfer data to and from a database.
Functional requirements definitions Functional Requirements are those that refer to the functionality of the system, i.e., what services it will provide to the user. Nonfunctional (supplementary) requirements pertain to other information needed to produce the correct system and are detailed separately.
Use cases
User first log into the system if the user is registered member , otherwise the can register himself/herself to the site, providing his/her user name , desired password and his/her every details that is required during new user registration. If the user wants to be an unregistered member he can choose to be an unregistered member of the site.
During the registration a check must be made whether an user already, or duplicate user name exists, then an error message is sent to the user. After the registration process is over user can log into the system with his /her user id and password. A check must be made, to verify the password of specified user against the database, otherwise an error message is sent to the user. After the user successfully logs in the system, he/she can update the profile, manage the community, post a message, or even can retrieve a message. (Note : An unregistered user cannot perform this operation. He/She can only view a message.).

System Analysis:
Systems development can generally be thought of as having two major components, in which one such component is Systems Analysis. Systems Systems analysis analysis is the process process of gathering gathering and interpre interpreting ting facts, facts, diagnosing problems and using the information to recommend improvement to the system. Analysis is a detailed study of the various operations performed by a system and their relationship within and outside of the system. system. One aspect of analysis analysis is defining defining the boundaries boundaries of the system and determining determining whether or not a candidate system system should consider consider other related systems. systems. During During analysis, data are collected on the available availa ble files, decision decision points, and transaction transactionss handled by the present system. system. Data flow diagrams, diagrams, interviews, on-site observations and questionnaires questionnaires are commonly used tools in analys analysis. is. We can say that
analysis specifies what the system should should do. System analysis is the management management technique, which helps us in designing a new system, improving an existing system or solving a system problem. There are key strategies for eliciting information regarding the user’s requirements:-
(i)Asking, (ii) getting information from the existing information system, and, (iii) prototyping.
Asking:
This strategy obtains information from users by simply asking them about the requirements. It assumes a stable system where users are well informed and can overcome in defining the problem. There are three key asking methods ,(i) Questi Question on may be ope open-e n-ende nded d or or clos closed? ed? An open open ende ended d ques questio tion n allo allows ws the respon responden dentt to formulate a response. It is used feeling or opinions are important. A close question requests are answer from a specific set of responses. It is used when factual responses are known. (ii) Brains Brainstor tormin ming g is a techn techniqu iquee used used for for gene generat rating ing new ideas ideas and and obta obtaini ining ng g gene eneral ral information requirements. (iii)) (iii Group Group conse consensu nsuss asks parti particip cipant antss for their their expect expectatio ations ns regard regarding ing spec specifi ificc variable variables. s.
GETTING INFORMATION FROM THE EXISTING INFORMATION SYSTEM Determining information from an existing application has been called the data analysis approach. It
simply asks the user what information is currently received and what other information is required. It relies heavily on the user to articulate information needs. The analyst examines all reports, discusses with the user each piece of information examined, and determines unfulfilled information needs by interviewing the user. The analyst is primarily involved in improving the existing flow of data to the user. PROTOTYPING
The third strategies for determining user information requirements are used when the user can’t establish information needs accurately before the information system to build. The reason could be the lack of an existing model on which to have requirements or a difficulty in visualizing candidate systems. PLANNING THE DEVELOPMENT PROCESS:
The development of the software has been done by the following the steps of Software Development Life Cycle. Development of the software was deemed essential and the particular solution has been adopted after devising the alternative solutions of the problem and conducting feasibility tests on all of them. First, the Soft First, has be been en do done ne.. The The preliminary requirements Software ware Requirem Requirements ents Specific Specificatio ation n has determination, followed by the requirements specification specification, data flow design, functional requirements requirements determination has been conducted. The next step is System Design. The Data Flow Diagram (DFD) and Entity– Relationship (ER) diagram are to be created in this phase. While the former identifies the major transformations and clarifies system sys tem requir requireme ements nts,, the lat latter ter provid provides es us with with repres represent entati ation on of the schema schemas. s. In this this phase, phase, the organization of forms and reports and a detailed description of the activities of the system have been provided.
REQUIREMENTS SPECIFICATION:
Requirements Specification Specification involves the basic requirements that the system to be developed should posses. These can be broadly classified into two types. 1. Perfo Perform rman ance ce Requi Requirem remen ents ts.. 2. Func Functi tion onal al Requi Require reme ment nts. s. Understanding the requirements specification is critical for the projects success otherwise the system does not get developed according to the customer’s wishes. Functional Requirements:
