Globus And The Eclipse-based Spatial Data Grid Services Architecture

The Grid has been the third popular technologic wave after traditional internet and web. It is so called the third generation application of internet. Actually, Grid computing has emerged as a new important technology upon the internet.It is orientated to be coordinated resource sharing and problem solving indynamic, multi- institutional virtual organizations.This article specifies grid concept, classification, goal, significance and characteristic with the related grid technology.It analyzs the grid system structure compared with Open Grid Services Architecture(OGSA), Open Grid Service Infrastructure (OGSI) as well as Web Services ResourceFramework(WSRF) between relation and difference. This article also mainly introducs the tool Gloubus Tookit realized grid technology and the grid middleware of data access and integration(OGSA-DAI). With using GT4 under the Eclipse platform the grid service is deployed and realized. It specifies grid service realization process. The Grid technology applies the spatial data access and integration is the current hot spot in grid engineering research. According to the question this article proposes the framework and the development flow of using the OGSA-DAI realization to the space data accessing service, and accesses space data file with the grid technology. Finally the article produces the demonstration result and summarized its work.
