Spatial Data Service Models in Grid Environment
This paper presents the data service models in data grid and points out the well-known catalogue based grid data manage model CDM cannot satisfy the requirement of multi-resource grid data application. Combining with the need of spatial data application gird, this paper gives out another two models, broker-based model BDM and direct manage model DDM. Through experiments with these models, the detailed comparison among them is also been given here.
