Description
Summary:Heterogeneity of the data leads to low utilization rate of resources, producing a large amount of information islands. This paper gives a new method to convert global query into local query which can be executed by OGSA-DQP based on OGSA-DAI and OGSA-DQP, achieving centralized and uniformed access to multiple data sources. This method has been applied to a real project, and has achieved good results.
