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,符合基于OGSA的网格标准。文中介绍了OGSA-DAI的框架模型和体系结构,分析了实现数据访问、集成的原理。通过具体的实例,详细介绍了OGSA-DAI的开发和应用过程。The OGSA-DAI project is concerned with constructing middleware to assist the access and integration of data from separate data sources via the grid. OGSA- DAI is compliant with OGSA based grid standards. Introduces the frame model and architecture Of OGSA- DAI, analyses the principle of data access and integration, the development and application of OGSA-DAI were illustrated by an example.
