Service Composition Modeling: A Case Study

Abstract

In the last years the innovation in technologies such as XML, Web services and component-based development has motivated the interest in business processes. For this reason various languages for design and implementation of business processes such as Business Process Execution Language for Web services (BPEL) have arisen. However, a weakness of these languages is the difficulty to be used by business analysts in the early stages of the development process. In this work we present, through a case study, a model-driven process for the service composition modeling. The process begins with the identification of the services that will be offered to the user, taken into account the system requirements; and allows to obtain a service composition model. From this model it is possible the mapping to a specific Web services composition language
