The Research and Design of an Agile Service Composition Approach Model

摘要

Service- Oriented Computing is becoming an important paradigm in distributed computing area.However, most existing service composition technologies are not perfect for that they are developeroriented and only suitable for solving the problems in which requirements are definite and business processes need to be predefined. They also need to reload applications if the service composition changes.Therefore, the time is long and cost high. Hence, the paper brings forth an agile service composition approach model in the light of Web2.0 and traditional service combination technologies. This model makes the end-user free to compose services as they wish, as well as simplifies the composition task. It enhances the transformation from business to logic, and supports onthe-fly feedback. In addition, the approach model has a number of important features: it makes service composition more flexible and satisfies end-user's realtime requirement; it makes service more easy to use and the application level service reusable. The model is implemented in an enterprise integrated project as a validation.
