Finite State Machine Based Business Logic Model for Web Services Change Management

Immediate changes to business environments are never-ending occurrences in enterprise business atmospheres to meet the customers necessities in present and fast growing IT industry scenario. Also they must be aligned to IT to ensure the proper functionality of their services even after the changes are propagated at business logic layer. This needs a vital call for a vibrant replica to make possible the business analysts to handle these decisive changes unfailingly and sophistically through themselves without depending on the skills of Information Technology team. Also negotiating the changes amid business policies must be addressed to incorporate changes correctly and successfully. In this paper we propose a methodology and a reliable technique for the web services changes using Finite State Machine. FSM is primarily used for extracting the business logic and for dynamic generation of source code after changes are done at schema level by analyst himself. Evaluation of the proposed architecture with the help of the Software Architecture Analysis Method (SAAM) exposes that this architecture can greatly benefit by revealing its strengths before evolving the architecture further.
