OGSA-DAI数据资源管理器的研究与实现

Research and implementation of OGSA-DAI data resource manager

随着网格技术的逐渐成熟,越来越多基于网格的项目都开始采用OGSA-DAI作为访问分布异构数据源的中间层,以达到终端用户透明的存取分布、异构数据源的目标,然而OGSA-DAI原有的安装部署方式在一定程度上阻碍其得到更广泛的应用.在OGSA-DAI原有安装部署原理的基础上开发出OGSA-DAI数据资源管理器,实现了OGSA-DAI的图形化安装部署,并通过开发OGSA-DAI服务器端Activity扩展OGSA-DAI的原有功能,实现了对远程OGSA-DAI服务器上的数据资源的部署.

With the development of Grid Computing,more and more applications based on Grid are adopting OGSA-DAI as the middleware to access distributed and heterogeneous databases,so the client user can access the distributed and heterogeneous databases transparent.However,the original deployment method hindered the population of OGSA-DAI.This paper developed a OGSA-DAI data resource manager based on the principle of the original installation and deployment method.It realized the installation and deployment of OGSA-DAI graphically,and also developed new Activities to extend the function of OGSA-DAI,with the function provided by these new Activities to realize deploy data resources on the remote OGSA-DAI servers.
