In oder to solve the problems in rural surface water data exchange,it was considered that the parent node obtained the data from the sub-node,and the higher domination concept was proposed.Through the direct access of parent node to the database of sub-node,the data exchange mode was constructed,and then the mapping from target fields to local fields was realized by using XML,at last an automatic generation system for common database query was built to extract data and achieve the seamless exchange of data between the heterogeneous databases.
