基于OGSA标准的发票数据库网格IDBGrid的设计与实现

Design and Implementation of an Invoice Database Grid Based on OGSA

该文根据OGSA标准提出将分布于全国各地的成千发票数据库虚拟化,通过对原系统的重新规划与设计,建成一个具有超强的存储和运算能力的发票数据库网格IDBGrid,IDBGrid在Web服务资源框架基础上提供网格数据库管理系统注册服务、网格数据库管理服务、网格数据服务、网格数据库复制服务、网格数据库监控服务、网格数据库故障转移服务等,提供一个统一、透明的数据库网格访问和整合界面,通过网格环境下数据库服务器之间的协同处理达到提高资源利用率、运行性能,降低开发和维护成本,增强系统健壮性和可用性的目的,文章重点研究了异构环境下数据库管理系统的网格化管理的关键技术。

According to OGSA,This paper proposes that the thousands of invoice databases distributed all over the country should be virtualized,constructing an Invoice Database Grid （IDBGrid）with superior storage and computation capability by re-planning and re-designing the existing system.Based on WSRF,IDBGrid provides GDSR,GDAS,GDS, GDRS,GDMS,GSFS services,and an unified transparent database grid access and integration interface,consequently achieve promoting resource usage,performance,reducing the cost of development and maintenance,enhancing system robustness and availability by cooperative processting between database servers in grid environment.This paper focuses on the key technologies of Grid Administration of DBMS in heterogeneous grid environment.
