SOA is the main architecture in the future,this has become the consensus of industry,it also become one of the trends in middleware market in the future,buffeted by SOA, It is not only bring the change of the IT technology and applications,but also lead the middleware software industry as a whole pattern of the evolution of the market.In order to seize the high ground and win in the future competition,public companies are clamoring to get SOA, SOA also shows its powerfull flexibility among kinds of system architectures,so it will be the trend of the future.Although SOA has powerfull functions such as flexibility,fast development,rapid deployment and transparent management,because of its aim is the realization of enterprise integration in the future,this includes information systems integration,process integration and data integration and so on,which is involved in different enterprises on process and data exchanges,because of the history of different enterprises,there are big differences among enterprises in the initial system architecture, and there are also great differences in the circulation pattern, as well as data exchange among different enterprises,thus there have great difficulties in the process of the implementation of concrete.This thesis main introduces the concept of the SOA architecture,building elements, the purpose and the SOA concrete structure,it has also discussed specific network protocols as well as required technical and data transfer format that used in this architecture,during how to realize SOA, this thesis has discuss a new method~Business-Drive-Development,although SOA will become the trend slowly,but now a lot about SOA are still stay in the oral,there are no specific implementation plans,thus the development method in this thesis has certain advanced nature.it will turn the demand completion to the realization of services after new business generated,it has considered the differences among enterprises of the size and geographical differences. It discusses the Business-Driven-Development based on the three themes including service providers , service users and service managers.In this thesis, the main object is how to build services and call methods,for services provider, this thesis discusses it from creation,accession from existed systems,connective testing,storage and distribution. for services users,this thesis discusses how to find and uses it,at the same time discusses the architecture of the third-party agents in the collaborative process for enterprises.
