ETL多点缓存技术的数据仓库系统构建

摘要

Because of the database of data processing in a different standard, when the user data warehouse is constructed, different results might be produced. While ETL as data processing basic tools,can be in the process of building data warehouse to provide a stable,efficient,reliable data. ETL in data warehouse creation process plays an important role. This paper constructs a data warehouse based on ETL more cache technology, to provide users with a stable, high quality data warehouse.%由于数据库中处理数据标准不同,当用户构建数据仓库时,会产生不同效果的问题.而ETL作为数据处理的基本工具,能够在数据仓库构建的过程中提供稳定、高效、可靠的数据.ETL在数据仓库创建过程中起着举足轻重的地位,构建一种基于ETL多点缓存技术的数据仓库,可为用户提供一种稳定的、高质量的数据仓库.
