A Novel Data Exchange Model Based on P2P and Ontology

With the continuous development of enterprise informatization, there are a large number of heterogeneous data sources. So the requirement for the data exchange and integration in the different information systems becomes more and more prominent. According to the actual demand of data exchange, we introduce ontology and P2P technology, and propose a solution for the data exchange of heterogeneous data sources. First of all we propose a data exchange model based on ontology, and then introduce two aspects of the model-the construction of data source local ontology and the mapping between the various local ontology. Then, according to the function defined in the model, using JXTA technology, we put forward a data exchange model based on P2P and ontology, and meanwhile define the main components of the model.
