ETL工具的元数据集成与管理研究

Research on Metadata Integration and Management of ETL Tool

模型驱动的思想应用于数据仓库系统的元数据集成,基于公共仓库元模型技术设计了自行开发的数据仓库系统中ETL工具的元数据模型,并提出了一个基于元模型的元数据管理系统的框架。提出的方案可以有效地提高元数据集成与管理的效率。

Efficient metadata integration and management is a precondition of efficient run for data warehouse.In this paper,Model Driven idea is applied to metadata integration in data warehouse system.Based on common warehouse metamodel technology,the design of metadata model for ETL tool in detail is discussed.Finally,a metadata management system framework based on metamodel is proposed.The approach purposed in this paper can efficiently improve the efficiency of metadata integration and management.
