【Abstract】 The development of Internet economy will dramatically change the way we liveand do business, and the true convergence of communications, commerce and computingtechnologies will make enterprises more depend on information technologies to survive andget competition advantages in the transformation from traditional economy to new economy.Most companies have a heterogeneous environment of disparate systems, applications,processes and data sources, which play an important role in the enterprise. Although havingmany common fields among those system, they have to run independently themselves,without exchange each other. these phenomena is so-called "Information Isolated Island". Tochange this situation, companies face tow choices: one is to establish a entirely new and largesystem replacing those old systems; The other is application integration.Considering the costcycle and the possible dificulties during the process, the later is obviously relatively feasible.With the pressure of a competitive business environment there are more and more the needsto share data in business processes over different systems.The traditional EAI was confined to the internal integration of the enterprises, and hadlitle support for e-business, especially B2B applications. Meanwhile, the integration stylewas always point to point, so traditional EAI had many deficiencies, such as poorextensibility, complexity in relations, structural redundancy and management dificulty.Based on the analysis of the development and the deficiencies of current EAI, the thesisdescribes the requirements of new application integration models. Then combined with themessage method technology which is based on XML, it describes the goals of applicationintegration systems: adaptability, flexibility, reliability and simplicity. We use many methodsand technologies for integration, including distributed object, application server, MOM andMessage Broker etc. Then the thesis discusses the key technologies in the implementation ofthe hierarchy. To gain the extensibility, flexibility and independency, we adopt the externalinteractive gateway to implement the information interaction between the interior and theexterior of the enterprises. Then we build a platform of information exchange . We use themessage method which is based on XML for information exchange of heterogeneoussystems , proposing the solutions. The application integration softbus is realized by XML andmessage. The communication between applications is accomplished by resource adapters.According to the practical requirement of different departments , an application example hasbeen developed on information exchange platform.更多还原
