Analysis And Design To The Enterprise Application Integration System Of Kunming Telecom Company

EAI (Enterprise Application Integration) is one of the important methods by which modern enterprises can improve their information construction. The central idea of EAI advocates a general view to the application systems (AS) of the enterprise, and then integrate decentralized system by different types of IT technologies.As a popular and mature technology, many EAI related solutions and products have emerged. Now, the key issue we should research is the applicability between the EAI solutions and the application environments. The other core content of the paper is about a design of application integration system for Kunming Telecom.This article describes following parts:1. Annotates what is EAI. Introduces EAI related background and its development now and before briefly.2. Study and discuss EAI collectively. Make clear that essentially EAI is a solution and IT system architecture. From aspect of application, discuss and analyze four approbatory aspects of EAI (that is, user interface-level, data-level, method-level integration and business process-level). Propose and summarize the environment where these different levels of integration methods are used. Discuss and sum up the evolution of EAI from the perspective of technology.3. Study the technical features of some popular IT technology that applied on EAI, including CORBA, J2EE and XML.4. With the application of IBM Cross Worlds, completes the Kunming Telecom company EAI architecture design and its internal details, including: designs system of volume data and real-time data processing mechanism; forms the workflow of KPI statistics system; develops the interface between the EAI platform and application system; makes an internal communication process of the interfaces; designs the attributes of ASBO and these of GBO; makes collaborations process of the system; builds the EAI workflow to complete the KPI numerical statistics; designs the map between GBO and ASBO; implements the function of the data conversion in the system.The construction of the platform has been completed according to the design. Then it is put in the trial. The result proves the correctness and reliability of its design. This presents a new view of EAI and creative solution.
