| Along with the developing computer technology and the request of enterprise calculating cost, more and more computer application system has applied to the distributed computer system. Its core technology is to attain the across-platform integration through middleware.. Therefore, we design a new middleware named eEnabling which is oriented to Enterprise Application Integration. It can realize message exchange between any information system, support data exchange, support any message type and communication protocol connection and so on, meantime, it also could realize analysis and transacting of asynchronous data between different systems. This paper pay important emphasis on design and implementation of eEnabling middleware platform, based on analysis and summarize of middleware current developing status.This paper is arranged as belows: firstly it makes an introduction to the EAI model architecture based on eEnabling middleware, and analyze the design idea and basic principle of eEnabling middleware, then provide the detail introduction to three important modules in the inner of eEnabling module, they are data exchange module, communication transfer module, data transacting module. Data exchange module picks up the data created in the database via triggers, and then convert the data into XML Data File which matches XML Schema of source system. Contrarily, as soon as target system receive the XML Data File according with its XML Schema, the data in XML Data File can be loaded into target database.Communication transfer module support any communication protocols. We take normally used JMS protocol and SOAP protocol as example, introduce the process flow.Message transacting module realize the analysis and transacting of XML Data File from source system, then maps it to XML Data File matching with XML Schema of target System. Finally, on the basis of a practical project, this paper verifies the actual application effects of eEnabling middleware between information systems. |
