CHAPTER 8

CONCLUSION AND FURTHER SCOPE

8.1 APPLICATION AREA

This particular software, which has been designed and developed for

WINFOCOM SOLUTIONS (P) LTD can be used in various branches. The individual

modules can be used in different application areas. So we can conclude by saying that

this software can be used as a bundle of modules or either individual modules to cater to

the needs of the perspective organization.

8.2 CONCLUSION AND FURTHER SCOPE

The system has been incorporated successfully. Appropriate care has been taken

during database design, to maintain data integrity and to avoid redundancy of data.

Validations have been done instantaneously to avoid data redundancy.

This site was developed in such a way that any further modifications needed can

be done easily. It is user-friendly and all technical complexities are hidden.

The quality factors like correctness, efficiency, usability, maintainability,

portability, accuracy, tolerance, expandability and communicatively all are successfully

done.

Future enhancements can be done further in case of the Chatting Module where a

Private Chat can be included.
