| 摘 要： | 随着商业和科学研究领域中数据密集型应用越来越广泛，提供透明地访问分布式的、异构的数据源将成为这种应用的关键。提出一种基于网格数据仲裁服务（Grid Data Mediation Service，GDMS）的数据集成系统，它能够把网格中的分布式的、异构的数据源表示成一个逻辑上虚拟的数据源，并设计出了一种灵活的映射模式来描述构建虚拟数据源的过程。

| Abstract: | As data-intensive applications gain on importance on the commercial and scientific sector,it becomes crucial for success of the Grid to provide transparent access to distributed/heterogeneous data sources as well.This paper describes the data integration system based on Grid Data Mediation Service (GDMS).GDMS is capable of presenting distributed,heterogeneous data sources as one logical virtual data source on grid.We developed a flexible mapping schema to describe the building process of a virtual data source. |
