This paper introduces the background knowledge of heterogeneous data integration, as well as the knowledge of data integration. On the basis of the above, The author develops an ontology-based Heterogeneous data Integration prototype system, expounds the main framework and essiontial technology. Then the paper introduces its work in detail: it explains the very significance of using ontology as an comon semantic description and an global query model ,and illustrates the reason fo adopting LAV method ; then it builds the formal representation of the mapping between ontology and data resources, applies OWL to describe the ontology and the mapping ; defines a query language named by DIQL to query on our integration system , and supply the detailed arithmetic of reolving partial binding of LAV method、locating of data sources and query rewriting,etc. Finally,the paper demostrates and proves the result of research by examples .
