摘　　要：网格上的大量数据需要使用数据库系统来管理。介绍了与网格环境下数据库系统相关的概念,讨论了网格数据库的关键技术,包括WebServices、OGSA、OGSI、Globus Toolkit和OGSA-DAI。OGSA是网格数据库的一种以服务为中心的结构形式,以此为基础的网格数据库研究正不断展开。分析了网格数据库研究的趋势,建议数据库研究人员对网格数据库作更多的研究,致力于从网格应用中发现并解决网格数据库面临的新问题。Database system is needed for managing the large amounts of data on the grid. In addition to introducing the conceptions relevant to database system on the grid, topics are discussed in key technologies of grid database which include web services, OGSA, OGSI, Globus Toolkit and OGSA-DAI. OGSA is a Structure form of grid database which take service as centre. The research on grid database base on this spread out unceasingly. Analyse the trend of the grid database research and suggest that the database researchers need to do more research on grid database by finding and resolving the new problems caused by grid applications.
