| As companies seek to link their existing software applications with each other and with portals, the ability to get their applications to exchange data has become critical. It is enterprise application integration (EAI). There are different approaches to EAI. Some rely on linking specific applications with tailored code, but most rely on generic solutions, typically called middleware. XML,combined with SOAP and UDDI is a kind of middleware.When the scale of software is wider and the requirement of enterprise is changed fleetly, EAI has many problems which are difficult to solve. integration software system is criticized that be short of sufficient flexibility。A new approach can help EAI. It is service oriented architecture (SOA). In an SOA, resources are made available to other participants in the network as independent services that are accessed in a standardized way. This provides for more flexible loose coupling of resources than in traditional systems architectures。Microsoft? BizTalk? Server 2004 is a platform of orchestration management and EAI, which is embodiment of the SOA programming pattern. The platform supports the goal of creating business processes that unite separate applications into a coherent whole. It enables developer to connect diverse applications, and then to graphically construct and modify business processes that use the services those applications provide.This paper introduces the Architecture of BizTalk server 2004 and how to use the platform to design and implement an integration system. The platform is applied to a prototype system, which will comprise three software systems-CERP, CPDM, and CDO. There are two main functions in the prototype system. One is integration of data: to transfer EBOM of CPDM to PBOM of CERP, the other is integration of business process: an automatic modify management orchestration. This paper also describes the main implementation steps implementation of the prototype system... |
