Abstract
among the various departments of an organization and the ancillary units has been geographically distributed and the coordination has become more complicated. Web-based services with service-oriented paradigm enable flexible and dynamic interoperation of autonomous software units. Service oriented architecture can be realized with web services as the low level building blocks and higher level services can be composed with the Business Process Execution Language. In this paper, effective interaction among the various departments of an organization and the ancillary units is studied and a solution based on composite web services is proposed. Intricacies involved, issues connected with this type of composition will be studied with reference to engineering job outsourcing environment. This study provides orchestration mechanism which leads to composition of new higher level abstract services.
