Research Of B2B Application Integration Based On Web Services

As the advancing of the E-Commerce and E-Government Affairs, the level of the informationizing for the whole society has greatly improved. However, it also confronted with many problems; especially the problem of the so-called 'Isolated Island of Information' has not been resolved completely. Besides, with the development of the society and economy, more and more enterprises begin to realize the importance of the connection and interaction among them, which leads to the urgent demand for B2B Application Integration. So, it is becoming more and more important to resolve the problem of B2B Application Integration.This paper mainly containt the following work.Firstly, the paper makes a profound analysis of the inadequacies for the traditional B2B Application Integration, e.g., traditional methods for B2B Integration is almost the peer-to-peer application integration. That is to say, the integration among N systems needs N×N times development. At the same time, the article also deeply analyzes some crucial technologies and software building ideas which are related to the B2B application integration, such as Service-Oriented Architecture, Web Services, Business Process Execution Language for Web Services, etc.Secondly, under the Architecture Theory of SOA, based on the technologies of Web Services and BPEL, the paper proposes a set of B2B Application Integration Design Framework based on Web Services. The Framework's uniqueness is as following, through the dividing and separating of the B2B Application Integration's function, this paper proposes a six-layer design model. Following the model, this paper proposes a universal B2B Integration Framework based on Web Services. Meanwhile, this paper points out some rules and principles when implement this Framework, which leads to the Framework not only having the advantage of layer-design, but also having strongly maneuverability.Lastly, considering the practical situation of Guizhou Province's Health Statistical Project, this paper propose B2B Application Integration Design Framework of Health Statistics, which based on the technology of Delphi, Java 5, XML, Tomcat, Xfire, UDDI4J, ActiveBPEL, and so on. This Framework has the characteristics of the platform independency, flexibility and extensibility, etc. It also achieves the peer-to-all B2B Application Integration, which can greatly reduces the difficulties and workload of Integration, and saves the costs of B2B Application Integration. So, the B2B Application Integration based on Web Services has a great value of application.
