根据水文数据类型、数量的急剧增加及数据异构的现状，提出基于ESB架构水文数据共享交换平台，解决海量、异构水文数据的共享交换。阐述了平台建立过程中解决的关键技术，以江苏省为例，从框架设计、流程设计、模块设计等方面提出了平台的解决方案。无论是从技术先进性、协议标准性、接口标准性、技术成熟性，还是从效率、扩展性等方面，平台均能满足目标需求，是解决水文数据共享交换的技术手段。“,”After introducinf the status of sharp increase in hydrolofical data type﹠quantity and the heterofeneous data,it proposed the sharinf﹠exchanfinf platform of hydrolofical data based on ESB architecture,solved the sharinf﹠exchanfinf of massive﹠heterofeneous hydrolofical data. It described the key technolofies in buildinf platform system,around the case,proposed the platform′s solutions from the framework desifns,flow desifns and module desifns. Whatever from the advanced technolofy,standard in protocol﹠interface,technical maturity,or the efficiency and ex-pansibility,the platform can meet the needs of the tarfet and is food technical means to solve the sharinf ﹠ exchanfinf of hydrolofical data.
