Abstract

In traditional SCW environments, related web services are integrated into business processes. Web service still brings less than expected benefits to small corporations and end-users for two reasons: 1 the web service only focuses on data level and is difficult to implement the presentation-centric business contexts. 2 The small corporations and end-users usually do not have enough IT competences to write a client or user interface to interact with web services. In order to solve these problems, the author proposes a presentation-preserved compositional approach for service-oriented architecture PCSOA, which extends the existing data-oriented compositional approaches for web services to provide a more flexible methodology to orchestrate both data level and presentation level services during the workflow integration. A prototype is also built to validate the feasibility of the approach.
