摘要
数据网格是网络环境下有效共享和管理存储资源和分布式数据资源的大规模、可扩展的框架结构,它适应数据密集型应用对网络环境下数据共享和处理的需要,并给用户提供透明访问远程异构数据资源的机制。论文将数据网格技术应用到水质预报系统中,有效解决了水质预报系统中有效获取、处理淮河流域Tb、Pb的水情、水质数据等难题,并获得了较好的实用效果。
Data grid architecture provides a large-scale,scalable infrastructure for the effective sharing and management of storage resources and data that are distributed across network environments.Based on the requirement to data sharing and managing of data-intensive computing application,it provides the mechanisms for transparently remote accessing to heterogeneous data resources.In this paper,the application of data grid in Quality Prediction System of Huai River effectively solves the problem of effective obtaining and processing the thousands of Tb or Pb water data of Huai River in Water Quality Prediction System of Huai River and obtains good practical effect.
