数据网格技术研究

数据网格是网格环境下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格环境下数据共享和处理的需要，给用户提供了透明访问远程异构数据资源的机制。文章首先分析了数据网格的研究背景和设计原则，并深入研究了数据网格的关键技术，最后对现有几个较成功的数据网格研究项目进行了分析和比较。

Research on Data Grid Technology

Data grid architecture provides a large-scale,scal-able infrastructure for the management of storage resources and data that are distributed across grid environments.Based on the requirement to data sharing and managing of data-intensive computing application,it provides the mechanisms for transpar-ently remote accessing to heterogeneous data resources.This paper analysis the research background,principles following in developing a design for the data grid architecture firstly,then deeply studies the key technologies when designing a data grid,finally analysis and compares several successful data grid re-search project.
