A New Architecture of Data Access Middleware under Grid Environment

Data sharing is one of the most important research areas in data grid. Distributed data resource and heterogeneous data schema bring difficulties to data Access and sharing. This article mainly focuses on how to deal with the heterogeneity of data schema and put forward a blueprint to solve the data access and sharing problem of heterogeneous physical data resources in the grid. To solve this problem we propose the SDB resource model which extracts three data layers from the physical data resource in order to facilitate the access and sharing of data resource.
