In order to solve problem of distributed heterogeneous data in water business application,a data integration scheme which combines data mapping and data collection is proposed in this thesis.The scheme carries out data collection through pattern copy by data transformation middleware between databases,and integrates large quantities of low-rate data by data mapping technology based on federal database,then realizes water business applications standardization and water information service integration by adopting component conception,which meets the needs of cross-basin hydrological data sharing and collaboration.The results show that this method can effectively implement data integration of different data sources,and provide a basic data platform for hydrological information system.
