Wei He · Journal of Beijing Institute of Graphic Communication · 2010
According to information isolated-island phenomena in enterprises,this paper introduces several common data integration methods,but the semantic heterogeneous problems still exist in the schemas of the data integration.Based on the fact that ontology can describe precrisely conceptual system and domain knowledge,this paper proposes an ontology-based heterogeneous data integration model,and introduces all components of the model,and emphatically analyzes key technologies——the creation of the ontology database and processing of the query.
