基于关系模型的网格监测系统实例研究

Research on Relational Model-based Grid Monitoring System Example

网格自 20世纪 90年代中期被提出以来,得到迅猛发展,被称作因特网的第三次革命。而网格资源监测是网格系统中非常关键的一环,成为重要的研究方向。分析了网格监测系统的要求,以及现有基于层次数据模型的监测系统的不足,然后着重从技术角度研究了基于关系数据模型的网格监测系统———R GMA的具体实现。指出了R GMA未来的研究方向以及网格监测技术的发展趋势。

The grid has been developed greatly since it was proposed in 1990s, which is called the third revolution of the Internet. The grid resource monitoring is one of the critical problems of the grid, and has become an important research direction. This paper analyses the requirements of the grid monitoring and the lacks of the monitoring system that is based on a hie-rarchical data model. Then it gives a detailed presentation and analysis of the key techniques of the R-GMA, which is based on a relational data model, and points out the research directions of the R-GMA and grid monitoring.
