摘　　要：OGSA-DAI(Open Grid Services Architecture-Data Access and Integration)致力于构造通过网格访问和集成来自不同孤立数据源的中间件。文章分析基于OGSA的数据访问和集成服务框架,给出基于OGSA-DAI的数据访问与集成方法,提出扩展OGSA-DAI以支持一般性数据访问和集成服务的基本思路,最后给出在网格层整合OGSA-DAI与数据存储的整体架构。The OGSA-DAI project is concerned with constructing middleware to assist the access and integration of data from separate data sources via the grid. The framework of OGSA-DAI was analyzed. A basic view of data access and integration services based on OGSA-DAI was described. A method for generic data access and integration services through extension to the OGSA-DAI is presented, and an integrated architecture of the data resource with OGSA-DAI in grid layer is given.
