Research Of System Integration Based On Soa On J2ee Platform

As company's informatization degree has gone deeper and deeper, the information system during the company informatization becomes a lot of "infomation islands". System integration is a inevitable link during the informatization procedure, so a good integration way is in urgent need. This paper, System Integration Based On SOA On J2EE Platform, is for this kind of need, so this study has some real meaning.This paper analyzes the integration of the current system status and development trend, introduced a number of existing heterogeneous systems integration method to solve. Through comparative analysis of traditional systems integration methods, and CORBA,.NET and other integration methods, explains why the integrated approach named system integration based on SOA on J2EE platform is used, it also introduce integrated framework, structure, process, database access methods design. The integrated use of the SOA, Web Service, XML, J2EE technology, to solve the problem of heterogeneous system integration, and improve the reusability of the system, reducing business costs. End of the paper the examples and instances of the project were introduced, and analyze the integration needs of an instance, realization method and technical, the design process, the future effects.The integrated approach of this paper is mainly to solve the heterogeneous data integration system, making the development of different programming languages, running on different operating systems, different back-end database systems to interoperate. And the idea makes use of SOA technology and business separation, developers and businesses to reduce the workload of staff, making integration easier, more efficient implementation. With these traditional systems integration compared, SOA has a coarse-grained, loosely coupled the advantages of the requester only needs to request the corresponding service system can access the services provided by service providers to realize the corresponding function, does not need to know service internal implementation details, is conducive to the realization of quick and easy system integration. SOA also increases the reusability of software, high reusability of software will help improve the efficiency of system integration and lower costs. J2EE technology is platform-independent nature, can be Windows, Linux and other operating systems on different transplantation, also has good compatibility. This issue addresses the increasing number of enterprise systems to preserve difficult issues such as spending too large, is conducive to interoperability between applications.
