To resolve the problem that heterogeneous data integration system which used hybrid ontology approach lack of scalability,the database design process on an ontology-based formal structure of data source is analyzed and two types of integrated operations are introduced,which extend global ontology by adding their own concept specializations from local sources and project the instances of local sources onto the global ontology.The analysis of integrated operations is proved that the approach ensures the autonomy of databases design in local source and allows the system to have good scalability.
