In this paper a novel ontology-based data semantic fusing frame named ODSF is introduced, the basic element of ODSF is dataset its semantic is obtained by the mapping between the domain ontology and dataset. ODSF adopts nested relation model to represent the schema information of dataset, and realizes the data fusing from coarse-grained level to the small-grained level by wrapping the datasets registered in virtual database as a new dataset. We also present the semantic model of ODSF, query executing process and algorithm of virtual database, so ODSF can provide the semantic supported and QoS supported data access for user. The experiments demonstrate our work and show the feasibility and effectiveness of ODSF and its key techniques.
