J2ee-based Enterprise Application Integration Applied Research In The Telecommunications Industry

With the rapid advancement of communication technology, enterprise resources of Telecom industry continuously dilate and applications deployed become more and more, so Telecom industry need the uniform information system to support SOA. As a result of this change, HUNAN Telecom needed to integrate its online CRM, TSF and other systems. It had to integrate all existing services to a virtual platform for uniform services. This entailed integrating access to the existing applications that provided these services. Started from angle of Hunan telecom system integration, based on J2EE, this thesis discusses extensible Enterprise Application Integration (EAI) technologies and their relations. Toward several primary aspects of EAI, there are some creative opinions, resolvent, and concrete methods are discussed in this thesis.This thesis analyses the newest research production and the applied status, including common EAI architecture, and the common methods of EAI. Basic on these, an architecture structure which include enter, enterprise gate, EAI bus and system is designed and a real time and concentrated platform is set up. The old systems of Hunan Telecom are loosely coupling connected with the center of the platform. From the view of the data integration, an innovative detailed idea and method of the architecture for realizing data integration is designed in this thesis and Date Access Object (DAO) mode is used in designing dependable and strong data integration. In the aspect of the business integration, the way to realize the universal interface in business integration is expatiated in the thesis. By this universal interface, the problem of the high frequent changed interface in business integration is solved. Finally, from the angel of the User Interface integration, a creative UI development architecture of Model 2X, which reduce the difficulty in UI integration and applied in actual project successly, is offered in the thesis. The effect of architecture is well in practical application.By constrcting Enterprise Application Integration and the structure of data, applications of Hunan Telecom are integrated and information isolated island is broken. The integration implements the automatization of business flow and transparent communion of data, unifies the sharing data models and ensures the veracity and real time of data. So that systems of Hunan Telecom can be constructed in standard and loosely coupling mode. As a result of the integration, the cost of maintenance is reduced and the flexibility is advanced.
