Abstract :
Aiming at the existing problems with traditional integration technology, the system structure, service and workflow of OGSA-DAI are analyzed thoroughly. Based on OGSA-DAI extension, the data heterogeneity of semantic is shielded by schema mapping. An integration model is proposed to solve data integration and distributed query under the grid environment, achieving transparent access to distributed heterogeneous data and associated process.
