Software Requirements Specification

1. IntroductionTHIS SRS PROVIDES A COMPLETE VIEW OF OUR PROJECT

This SRS will give you1) DYNAMIC PERSPECTIVE that shows the phases of the model over time.2) STATIC PERSPECTIVE that shows the process activities that are enacted.3) PRACTICAL PERSPECTIVEthat suggests good practices to be used during the

process.

1.1 Purpose:

The purpose of the SRS is to specify why the system needed and the requirements are

that need to be fulfilled by the system. Along with the full functionality, the actors and

their purposes will also be expanded. This srs provide us basic idea of our system. The

motto of the software is: AN ENIVORNMENT TO SHARE IDEAS

Factors behind the motivation of this system are to provide user friendly environment

for interaction between students and teachers. Also to nurture the creativity from

student

1.2 Scope:

In this SRS, we shall be detailing the overall functioning of the system rather than indepth look in to each and every operation performed by the various actors involved.This SRS shall directly affect our final project report. As this is the first version, as and

when the system is reviewed alterations and improvisations will be done in theupcoming versions. The system will be prepared keeping in mind the Diagramsattached.Basic features: Create different system users and assign different roles with related permissions.

1.6Overview:SRS includes two sections overall description and specific requirements

Overall description will describe major role of the system components and

interconnections.

Specific requirements will describe roles & functions of the actors.

2.0 Overall Description:THIS DESCRIBES the interaction of the client with the product the client can

post article view article rate article and comment on it.

2.1 Produc t Perspect ive:

The web pages (html/JSP) are present to provide the user interface on client side.Communication between client and server is provided through HTTP protocols.

The Client Software is to provide the user interface on system user client side and forthis TCP/IP protocols are used. On the server side web server is for servlets, ejb anddatabase .server is for storing the information.

CLIENT SIDE INTERFACE for adding interactivity we will usejavascript jquery and ajax

MANAGES THE ACCOUNT

Login:In order to access other specific functionalities a user must login to the system. AllUsers can login to the system using their user name and password.Name of use case:loginDescription:client enters user name and password and the system authenticatesThe userPreconditions:The user account is existing in the database and has not yet loggedInNormal flow of events:1)The client enters user name and password.2)JavaScript validates the provided information using regular expression.3) the Jsp page passes the request to Servlet.4) the Servlet checks against database and returns TRUE.5)A bean instance is created and property is set by JavaScript.6) User is asked for the option of continuing with previous session by java script.7)Based on user input the session detail is got from Servlet and DOM is updated

Alternative flow of events:

1) The client enters user name and password.2) JavaScript validates the provided information using regular expression.3)the Jsp page passes the request to Servlet.4)the Servlet checks against database and returns FALSE.

User Specific Functionalities:

3.2 Supplementary Requirements24 x 7 Availability If the base is now the entire world, staying open 24

Hours a day becomes critical. Because system can be an automated Process, soIt can stay open for 24 hours a day. So UPS support must be on server site forAt least 8 hours in case of power failure. System will remain inaccessible toUsers at 2:00 to 4:00 am for backup and maintenance purpose.Dynamic Website -Many early Web implementations consisted of staticHTML pages. This becomes very difficult to manage if the number of pagesgets too large. An effective system should be largely dynamic taking advantageOf technology that automates this process rather than relying on manualProcesses. Application should serve dynamic user based customized webPages to its clients from server.Integration with existing enterprise systems Any existing Web site that

Relies on the manual duplication of data from another system is one that canBe improved. Most of the business data in the world today exists in enterpriseServers that can be connected to the Web servers to make this process farMore effective.

Provide good performance and the ability to scale the server The WebApplication Server should provide good performance and the ability toManage performance with techniques, such as support for caching, clustering,And load balancing.Providing session management capability -Web application developersShould not spend valuable time worrying about how to maintain sessionsWithin the application. The Web Application Server should provide these

services.
