一种基于XML的异构数据集成平台研究

Research of a Heterogeneous Database Integration Platform based on XML

异构数据集成为不同自治、异构、分布的数据提供一个统一的全局数据视图。本文提出一种数据仓库-中介器数据集成方案,引入数据缓冲机制,将历史数据存入中心数据库中,频繁访问的静态数据写入数据缓冲区,提高了异构数据查询的效率。

Heterogeneous data integration provides a unified global view of data for various autonomous, heterogeneous and distributed data. This paper proposes a Data Warehouse-mediation data integration schema, which improves query efficiency of the heterogeneous data through bringing in data buffer mechanism, storing history data into center database, and writing static data accessed frequently into the data buffer.
