COMPOSITION OF WEB SERVICES BASED ON DATA DEPENDENCY SPECIFICATION

摘要：

As the number of available Web services is steadily increasing, there is a growing interest for reusing basic Web services in new, composite Web services. However, most current Web services choreography proposals, such as BPEL4WS or WSCI, need a fixed execution flow previously designed by human, thus the adaptability of Web services can not be fully used. Through formalizing the description of single Web services, a Web services composition mechanism based on dependences between data is developed and a flexible and self-adaptable workflow model to compose Web services automatically is proposed.Furthermore, the method of verifying the integrity and consistency of data is given, so that the model is more easily saleable.
