Research And Application Of Integrated Technique Based On Web Services

With the rapid development of information technology, enterprise application integration is more and more paid close attention to. Because of inherent models and heavy reliance on its own protocol, main integration technology, namely RMI, CORBA, DCOM, have some defects in flexibility and mutual manipulation. Service framework provides enterprise application integration with a dynamic and extendible programmed. Web Services technology is gradually mature, and it offers SOA and enterprise application integration with technical support.This thesis will be in accordance with the characteristics above, and the traits of Web Services, such as its normatively, loose coupling and highly integration. Basing on the design methodology and technology of Web Services application integration model, this research will finish exploiting application integration system of certain enterprise. It aims at achieving the cross-platform between enterprise and customer information, between systems of headquarters and branches. Moreover, the extendibility and mutual operation of systems enhance obviously.Web Services Application integration model based on .NET, provides internet application system integration with a more complete solution, and also gives a new design and developed mode for the construction of enterprise informationization. The main research questions and conclusion are showed as follows.1. The thesis will analyze the problems existing in the traditional integration project, discuss the technical traits and its system structure of Web Services, and also analyze the key technology and core protocol of Web Services, such as XML, SOAP, WSDL and UDDI.2. It brings forward a hierarchy integration model based on Web Services, and also have analysis of some key problems including design model, structure of systems, key technology and development mode of integration. The model can satisfy the traits of distributed application integration, and it has better universal property and compatibility. Thus, it can avoid the phenomenon of information island effectively.3. The thesis exploits enterprise application integration system based on Web Services. It constructs an integration platform of enterprise information and application. Meanwhile, it also discusses exploitation and realized methodology of enterprise application integration based on Web Services. E-R charts constructing database and data dictionary, legacy system and integration of data, and the integration of new exploitation service are included.4. It brings the security of enterprise application system based on Web Services into effect. The Security Strategy of enterprise is well depicted. It selects security method fitting Web Services, so privacy of the users who log into the enterprise information system is well protected.
