Abstract :
OGSA-DQP provides distributed query processing functionalities on top of OGSA-DAI, presenting the multiple databases as a single one, but it does not address heterogeneous data semantic integration requirements. This paper show the query reformulation based on rules on top of OGSA-DAI and OGSA-DQP, which can implement heterogeneous data semantic integration, and users can submit queries over a single database and receive the results from multiple databases that semantically correlated with the former on by it.
