Research And Implementation Of Enterprise Service Bus Based On SOA

Service-Oriented Architecture (SOA) is a component model that inter-relates an application's different functional units, called services, through well-defined interfaces 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 reusability, and to integrate all technologies, protocols and applications. For this reason, the IT forum creates an abstract layer focus on the "service" to reduce the underlying complexity by integrating all applications and technologies. Such a layer for services is called Enterprise Service Bus (ESB).The thesis first shows the research on theories of SOA and Web Services. By compared with traditional EAI approach, the thesis summarizes the highlight and trend of SOA, then analyses the definition and features 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 SOA and ESB, and also with absorbing of some technology specifications, a prototype of enterprise service bus AmsESB is designed and implemented.At the end of the thesis, an application sample based on AmsESB is given. 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 of succeeding jobs.
