网格环境下的数据库系统

The Database System in the Grid Environment

目前网格上的各类应用系统几乎都是使用文件来保存数据,因此人们对如何将数据库系统集成入网格这个问题研究甚少。如果网格要在将来支持更大范围的应用系统,那么必须要解决将数据库系统集成入网格这个问题。本文在分析网格环境对数据库系统的需求的基础上,总结了将数据库系统集成入网格的两种方法,并分别对它们做出评价。

Until now, almost all of the Grid applications use files to store data, so little has been done on the integration of database systems into the Grid. If the Grid is to support a wide range of applications ,we must solve the problem of integrating database systems into the Grid. This paper firstly examines the requirement of the Grid environment to database systems, and then summarizes two methods to integrate database systems into the Grid. Finally,we give a short evaluation on these two methods.
