Abstract :
Plenty of structured data existing on the grid need to be managed by databases, but there is little work available on grid-enabled databases. Two problems lie in current research: the first is the deficiency of a uniform management and access method to various kinds of databases; the second is that query efficiency decreases rapidly with the increase of the amount of data records. Metadata plays a critical role in grid databases integration, so a layered metadata model is put forward which comprises information of data storage, data properties and relations between data objects. Through the metadata model, the distributed, heterogeneous data resources can be accessed uniformly and efficiently. At last an example of hospital information database system proves the validity and feasibility of our model.
