中文摘要: ETL包含数据的抽取、转换、加载三个部分，是构建数据仓库的重要环节。为解决异构数据源集成问题，本文提出了基于元数据的数据交换系统，并在该基础上阐述了数据交换系统中的任务设计模型和任务调度模型。最后介绍了数据交换系统中的主要算法以及设计模式。

中文关键词: ETL 元数据任务设计任务调度作业

Abstract:ETL containing three parts of extracting ,transforming, loading is one core of building the Data Warehouse. For the sake of heterogeneous data source integration, this paper puts forwards a model of the data exchange system based on ETL Meta. Further, a task designing model and a task designing model are raised in in this paper. Last, the article recommends a main algorithm and the designing model in the data exchange system.

keywords: ETL meta data task designing task scheduling job
