Research And Implementation Of Application Integration Based On SCA And Web Services

Along with the further development of global economic integration, the smart and free service integration has been the hotspot of the research. The enterprise hopes it could integrate its inside and outside information and simultaneously update this integration at any moment as well. In response to this request,Web Services has been increasingly attracting the attention of IT field and business community by its splendid interoperability and the loose coupling characteristic. Accompany with varied research extending its application, it's behind conception-service-oriented architecture (SOA) has been considered to be occupying a more and more important status.Although Web services is the best practice of SOA, it just prescribes the constructing single service,which does not point out the problem of the assembly of services,furthermore Application Integration based on SOA should be compatible with traditional integration technology,not only be limited to Web Services.Papers address above issues in depth research.For solving the problem of service combination and assemblage, firstly this paper researched on the theory and system structure of using Web Service for integration based on SOA, gave an introduction on the design idea of service-oriented, compared SOA with Web Service and elaborated the relationship and difference between them; then, according to study on the deficiency of traditional Web Service integrated method, take the advantage of SCA integration, the author improved the conventional Web service integrated model which based on SOA, also on the basic of combination between data access service and SCA, Web Service proposed a new integration structure for application(namely SSW architecture), which not only innovates the technology of Web Service on the applied integration, but also to some extent appropriately figure out the problem of service combination and data programming brought by application of SOA integration, while also simplified the exploring process of using SOA to construct the application system. Separating out traditional middleware programming from logical operation not only helps developers focus more attention on programming logical operation but also avoids spending plenty of time in the implement of floor layer technology. This total process very well handles the tightly coupled matter between the conventional module interface and its transmission protocol; and simplifies the progress of the operation module exploitation, combination, and deployment; and enhances the system's portability, reusability, flexibility and also greatly improves its testability as well.Finally, This paper designs a new integrated SCA frame based on SOA after the discussion of the feasibility and necessity of SCA integration. It also designs a suitable service process according to the practical situation. Finally it explains the method of constructing SCA components, configuring modules, establishing client-side, setting up application module and citing module, accomplishing the application module calling from Web Service's binding module on the basic of practical example. The paper has validated the feasibility of study.
