基于Oracle／Linux环境数据抽取技术的研究与实践

Study and Practice of Data Extraction Techniques Based on Oracle/Linux Environment

数据仓库的核心技术之一是建立数据集市和跨平台数据抽取。以Oracle/Linux计算服务器为运行环境,研究和描述了3层计算架构中跨平台抽取Oracle/unix宿主系统数据库数据的关键技术,并提出数据抽取技术和数据仓库更新维护中的一些优化策略。

One of the core techniques for Data Warehouse is to build data market and to perform dada extraction across platforms.The key techniques to extract data across platform from the database of Oracle/Unix host system in three tiers calculating architecture have been studied and described in this paper,and several optimizing strategies for the data extraction techniques and maintenance of data warehouse including update are presented.
