Colleges and universities have accumulated large amount of isomerism, heterogeneous data source in the process of information construction. It is an urgent problem that how to integrate effectively the related data resources in the heterogeneous data source. A new solution is proposed to integrate heterogeneous data based on web services. On account of advantages of web services technology in heterogeneous data integration, the design idea of virtual data in database is adopted. The solution designs field dictionary table and field mapping table, and effectively solves the most difficult problem of semantic heterogeneity in heterogeneous data integration, and discusses the feasibility of the solution from the aspect of data model translation and global query. Experiments show this solution is applicable and efficient.
