Abstract: For any large scale data integration application system or platform, the architecture of it decides the cooperation among different components of the system and thus decides the stability, availability and extensive ability of the system. To optimize system architecture, all factors in both internal and external environment need to be considered. In this study, with the analysis of the traditional data integration solutions and technical features of enterprise service bus (ESB) SOA_based architecture and implement approach are proposed which provides the theory basis and solid technical support for agriculture data integration and sharing.
