Research And Realization Of Electronic Office Systems Based On ESB

Service-Oriented Architecture (SOA) is a component model that inter-relates an application's different functional units, called services, through well-defined interface and contracts between these services. To optimize the IT infrastructure and deliver the service in time to make the SOA possible, IT forum needs an intelligent structure to reduce the complexity of the service usability, and to integrate all technology protocols and applications. For this reason, the IT forum creates an abstract layer focusing on the "service" to reduce the underlying complexity by integrating applications and technologies. Such a layer for services is called Enterprise Service Bus (ESB).The thesis first shows the research on theories of ESB. With investigation of project background, a preliminary solution of ESB system based on SOA theory is given. Then it analyses the system's architecture, executing strategy, communication and so on. With deep research on technology of ESB, and also with absorbing of some technology specifications, a prototype of enterprise service bus is designed.At the end of the thesis, an application sample based on ESB is given. By the connection of ESB, we applied a more flexible solution of banking on this demo without any modification for the legacy system. With the background of an archive management system of a motor manufacturing enterprise the functions and capabilities of the system are validated. The disadvantages of the system are summarized and improvements are proposed, which settled the base succeeding jobs.
