基于网格的GDBS系统实现及其关键技术研究

Implementation and Research on Key Technology of GDBS System Based on Grid

基于DAI,应用OGSA的服务层次概念,提出了数据库代理框架.通过组合低级服务,各种数据库的代理服务和生成实体的工厂服务,获得高级服务,即数据库代理.数据库代理利用元数据目录统一管理各种资源,屏蔽资源的异构性.并在此基础上开发出了网格数据库服务(Grid DataBase Service,GDBS)系统.

This thesis provides DataBase Broker Service based on the concept of layered services in DAI according to OGSA.By combining lower services and database service and factory service which create new entities,we build up higher service,DataBase Broker Service.DataBase Broker controls various database resources cooperating with Metadata Catalogue Management Service,and masks the diversityand volatility of various data resources.And based on these we have developed a system of grid database service.
