A Dynamic Reconfigurable-Based Approach for Connectivity Mismatches of Web Services

Abstract

Web services are the main stones of building and developing internal organization business workflow. If the connectivity of these web services is not well defined, companies that rely on them may face many problems especially when integration and composition are needed. Companies need a well-defined harmonic structure of the web service connectivity within their workflow. The most challenge of these companies is to keep their workflow structure harmonic by handling unexpected changes or new policies. In this paper, we face this problem by proposing a framework with supporting some dedicated dynamic reconfigurable algorithms to generate and develop an automatically efficient adaptor. This adapter is designed to work in the case of the behavioral and graph mismatches within the web services connectivity for business workflow. The proposed framework composes of two main engines namely pre-mismatch and post-mismatch detectors to detect the existing mismatches in both of the generated and the reconfigurable workflows with considering the possibility of existing mismatches within some composite web services. A real case study obtained from PayPal system is used to illustrate the proposed framework functionalities.
