Study Of Enterprise Application Integration Based On SOA And Smart Client

The information-based construction in most enterprises has already stepped into a new stage which develops fast and stably currently, some large enterprises are experiencing the transition from the foundation of formation-based management stage to the overall information-based management stage. But because that the information system enterprise used currently usually develops on the basis of a particular business target, and there are many differences in time using, departments, manufacturers, implementing technology and so on, making that the application information system operates independently, the data can't be shared, different business processes can't link up with each other automatically, respectively inner an enterprise there appears the"information isolated island"which can be seemed as an independent system.But with the development of Internet technology, electronic commerce, B2B, B2C and the technology of ERP, management models of enterprise are developing towards electronic and globalization. Facing the rapid changes of market, how to provide an IT infrastructure which flexible, reliable and changed by itself according to the requirements, to catch the opportunity and provide better service, is the current problem for many enterprises.This kind of IT foundation structure is usually also enterprise application integration, but the traditional enterprise using integration plan is always the integration which point-to-point, existing some weaknesses, such as bad integrated ability, bad expandability, bad interoperability and high integrated price.It may be a very good way to solve the problems of the traditional enterprise using integration when the SOA appeared, the SOA is a module model, it will applied the different function unit of procedure-service, build up a connection via defining interfaces and contracts. The interface is defined in a neutral manner that should be independent of the hardware platform, the operating system, and the programming language the service is implemented in, it makes this kind of service could communication using unified and standard methods.This article combines the SOA with the Smart Client technology, proposing one kind of new frame model of enterprise using integration. This article does the main task and the innovations are as follows:1. Analyzed the solution and structure of the traditional enterprise application integration, the layerof the enterprise application integration and the general steps.2. Analyzed the concept, characteristic, structure of the SOA as well as the safeguard to the Web Service, studied the concept, characteristic of the intelligent client side as well as the off-line function, based on the existing problems of traditional application procedure, had an important discussion of the ClickOnce technology, and analyzed the role, the operation, the agreement stack and the Web Services structure.3. On the basis of analyzing the SOA and the technical of Smart Client has designed enterprise using integration frame based on SOA and the Smart Client, and has analyzed each level function in this frame and has given the work principle. This frame has the merit of based on the opening standard, strong reuse ability, data integrity and simple operation.4. Studied the key technique of BPEL, designed a new management frame of the business process, and analyzed the development process of BPEL flow performance history. Put forward a solution for how to guarantee the automation and orderlines of the complex Web service carried out, which resulted from the logic and timing relationship of the basic service units.5. Analyzed the information-based present condition of the Shandong taifeng Spinning company, given a requirement analysis, design the system structure to solve the business enterprise information-based problem, has studied the seal & the issue technology of the ClickOnce application and the carry-over system with emphasis. With the continuous development of SOA technology and Smart Client technique, the application of two technologies in the enterprise application integration will bring revolutionary changes for the business information system, bringing about profound influence on business enterprise development.In view of the importance of the enterprise information and the huge research foreground of the SOA & the SmartClient technology, this article carries on the work has a certain theory significance and practical significance.
