Research On The Enterprise Application Integration Based On Web Services Composition

In the more open and flexible Internet environment, In the face of the Internet become more and more abundant data resources, computing resources and application of resources, through the integration of existing resources and restructuring resources appreciation becomes a new research idea. Service oriented architecture will emerge as the times require, the formation of resources to "service" as the organization unit, service interface defined in a neutral manner, independent of implementation services, hardware platform, operating system and programming language, the integration of resources conversion for Web services.At present, the development of research on Web services composition mainly includes the application of combination scheme. Existing Web service composition methods are mostly based on interface, artificial intelligence planning, based on the graph search and based on natural lan guage. At the same time, Web service composition provides an effective solution for enterprise application integration, and has caused widespread concern in the industry.Based on the analysis of the each key technologies of Web services composition, this paper mainly studies three aspects of the problem:First, introducing the association rules mining algorithm in the service chain combination method available, use association rules to preprocess the atomic services, replacing the weak relationship with a strong association between service and composition service chain, optimize enterprise business applications, integrated solutions for the enterprise; second, taking into account the colored Petri network modeling and verification function, proposes a Web service model based on colored Petri net, the combination of service accessibility, security and verify boundedness; finally, combining the above two kinds of combination method to realize the enterprise application integration about tourism industry.
