\The grid is following the tradition of the Internet , the third big wave after the Web , you can call it the third -generation of Internet applications . Grid computing is actually to build a group of emerging technologies on the Internet , and its goal is to achieve dynamic, wide-area distributed heterogeneous virtual organizations collaborative resource sharing and problem solving in many fields of science and engineering . Data showing explosive growth in the field of scientific computing and commercial applications , scientific computing and commercial applications in the future will also be data -centric , and the grid itself also uses a lot of structured data to its operation and management . Grid database technology to solve complex mass data access and management of an effective and important technology and will eventually become an important resource on the grid to provide data management services . The grid database integration grid database management research hotspot . The grid database integration able to use two or more grid database information , and use this information to build a database for the purposes of scientific research and commercial applications , provides a wealth of scientific value data and new discoveries . Grid data access and integration middleware in the grid database integration played a important role , and it is currently in the research and development stage . In this paper, Grid technologies discussed in detail grid database access and integration , and analysis of the development trend of the limitations of the OGSA-DAI middleware and grid database access and integration middleware . On the basis of in-depth research and analysis OGSA-DAI architecture and internal processes , the authors propose a new OGSA-DAI system architecture design and expand and improve the functionality of OGSA-DAI . Finally, the system related to the key technologies and programming skills of this new system , demonstrated results and summarize the research . The new system reflects the good grid database access and integration performance , easy to expand and portability strong . Of this research work will play a certain role in promoting the development and improvement of the grid database access and integration middleware .
