A data integration technology for the application service platform of the digital yellow river

Information sharing is one of the difficulties in the development of water information. Data integration technologies integrate various water conservancy data sources to provide users with highly efficient and transparent data access. Researches are hot on water conservancy domain data service integration systems adaptive to open, dynamic and changing Internet environment to guarantee the system service quality. This paper proposes a Web service-based distributed heterogeneous water domain data service integration framework (WDDSIF) to meet the requirements of data publishing and exchange among various units on the application service platform of the Digital Yellow River. The framework allows plug and play of data sources and their dynamic integration, and guarantees the consistence and real-time of data. The framework architecture has been put in use on the application service platform of the Digital Yellow River.
