摘要
数据仓库面对的是一个分布的数据环境,在这种环境中,存在多结点、异构的数据源。针对这一问题,本文介绍了使用数据库网关技术、元数据驱动的ETL(抽取、转换、装载)工具设计,实现多结点、异构数据访问以及异构数据之间的转换。
Data Warehouse faces a distributed environment, which contains multi-nodes, heterogeneous data sources. Considering above problem, this paper introduces how to design ETL -Extract, Transform, Loading- tools based on database gateway and Meta Data Driving technology. By designing these tools, we can access and translate the data lies in multi-nodes and is heterogeneous.
