Application Oriented Service Modeling And Publishing

With Service Oriented Architecture (SOA) is proposed, many software and its application are encapsulated into services, service been used also into people’s daily life. However, in a complex network environment, a single Web service can no longer meet the increasingly complex needs of users. Therefore, Web service composition has become an urgent problem. Dynamic and distributed characteristics of Web service let it not affected by external software and hardware environment, so that the combination of Web services becomes possible,。At the same time, the reliability of service composition has become a concern in the academic community. In order to ensure the reliability of the composite service, this paper proposes several service composition Trustworthy Normal Formats, through these Normal Formats standard reliability design and specification of SOA.According to the existing Web service composition editor lack consideration of reliable service composition and the credibility, based on previous studies, the first normal form, the second normal form, the first trusted type normal form and the second trusted type normal form, applied to service composition modeling and publishing work, through the trusted paradigm can restraint the service composition and improve reliability properties of service composition. According to the combination operation way and the call between the Web service component relationship between the combination of services which meet the paradigm is service Confidence level.Publish service can be divided into Code-First and Contract-First two ways, because the exist editor can generate WSDL, so the service must use the Contract-First, then WSDL generates Java code to publish a service for users.Finally, from the service component, trustworthy service composition and its core algorithm design, integrated service publication three aspects to describes of reliable service composition modeling how the editor. And also gives two actual cases to illustrate the availability of tools.
