Abstract :
In view of to the phenomenon of information island in education resource, this paper researched a distributed education resource data query system worked on Internet by grid technology in order to share and use the distributed and heterogeneous education resource database. It is the education resource distributed query datagrid (ERDQD). Then, it researched the technology and principle of accessing the database by OGSA-DAI and the principle of realizing the query from the distributed heterogeneous database.
