Sample SRS for Interactive Messenger

The software requirements specification is produced at the culmination of the analysis task. The function and performance allocated to software as part of system engineering are refined by establishing a complete information description. The introduction states the goals and objective of the software, describing it in the contest of the computer – based system Information content and relationships, Flow and structure are documented. Hardware, software, and human interfaces are described for external system elements and internal software functions.

A description of each function required to solve the problem is presented in the functional description .Probably the most important, and ironically, the most often neglected section of a software requirement specification is validation criteria. Specification of validation criteria acts as an implicit review of all other requirements. It is essential that time and attention be given to this section. The bibliography contains references to all documents related that to the software.

ABOUT INTERACTIVE MESSENGER

  The Interactive Messenger we developed has incorporated features like instant messaging, audio conferenceing,video conferencing, text to speech reader and white board .It boasts of having a database that authenticate the user and keep track of them .The messenger is based on client server architecture .It enables peer-to-peer communication between clients during video conferencing. The various functionalities of different entities of the software tool are listed below 

Instant Messaging: 

This functionality enables the user to pass textual messages between the users .It is of two type private chat and public chat.

Audio conferencing: 

This feature facilitates conversation between two clients 

Video Conferencing: 

It enables visual communication between the two clients

Text To Speech Reader:

 This unique functionality helps in the translating text to audible format. Text to speech reader lets you listen to text instead of reading on the screen. It also allows you to convert text into a MP3\WAV file so you can listen later. Create MP3files from your email, news articles and any text you want

White Board: 

It enables clients to draw and type simultaneously

2. THE EXISTING SYSTEM

o Yahoo Messenger
o Intra Chat
o MessengerLog4 Pro
o MSN Messenger
o LAN Spirit
o ActivePost Basic

 

2.1 Limitations of the Existing System

   
  There are various drawbacks for the existing system. They are

1) Not very user friendly
2) Errors may occur while logining
3) Maintenance of files becomes cumbersome
4) Searching report is a tedious job 
5) Time consuming

   

3.0 MINIMAL SYSTEM REQUIREMENTS

The hardware and software for the development has been selected based on several factors such as 
 Support
 Cost effectiveness
 Development speed
 Ability to create robust application in the least time
 Stability

USE-CASE DIAGRAM 

The use-case model is a model of proposed system’s desired functions and its environment. It serves as a contract between the customer and the developers. The Use-case model is used as an essential input to activities in analysis, design, and text.   The use-model is comprised of:
  .Use-case
  . Actor 
  .Use case diagrams

CONCLUSION

 
  This project has given a satisfactory solution for new age communication. The output is obtained according to the requirements. This software can be updated in the future. The project is user friendly. Security is the main consideration in this project. All the necessary validations are carried out in this project so that any kind of the users can make use of this software. This software is protected from any unauthorized access by giving user name and password during login process.

FUTURE ENHANCEMENTS

  In future we can implement and integrate Speech to Text functionality with the existing system. Thus it can lend a helping hand to blind users for communication. We also considering it’s prospective on its applicability in internet, and intranet also
