Querying And Splitting Techniques For Sba: A Model Checking Based Approach

Current approaches to fragmentation of services are not business-oriented. They are not based on a real temporal query language, and in general, they return execution traces instead of parts of the process. We propose in this work an approach for fragmentation based on model checking and slicing techniques. Fragmentation is based on business rules expressed in LTL. In our work the fragmentation does not consist in splitting a web service composition in a set of fragments. It is defined as the seeking of a single fragment that contributes to the verification of a business rule.
