Unified V- Model Approach of Re-Engineering to reinforce Web Application Development

The diverse and dynamic nature of elements and techniques used to develop Web Application, due to the lack of testing technique and effective programming principles which are used for implementing basic software engineering principles, and undisciplined development processes insure by the high pressure of a very short time to satisfy market request to develop Web application. This paper represent approaches of reengineering in web that how reengineering process can be carried out to evolution activities in legacy system as well we propose the V-model for re-engineering process. This paper presents the need of the technologies and approaches for building new web-services from existing web-applications. In this paper we present the processing of V-model for Reengineering in web application which is the extension of V- model used in software domain. In our approach V-model incorporates with the methodology throughout the phases of web development process to re-engineer the web system.
