基于元数据驱动的企业级数据仓库系统

摘要

通过对元数据建设和维护及其管理系统结构的深入研究，提出一种基于元数据驱动的企业级数据仓库系统架构。该系统架构采用关系模型数据结构，并通过元数据接口和元数据驱动引擎的设计开发将数据仓库中各模块的反馈信息与其元数据存储进行交互，实现由元数据驱动数据仓库系统的运作机制，解决了一直以来元数据难以更新维护、数据质量检查效率低的问题，提升了对企业级数据仓库的管控能力。%Based on in-depth study of the construction and maintenance of metadata and its management system structure, this paper presents a metadata driven enterprise data warehouse system architecture. Relational model data structure is used in the system architecture through designing metadata interfaces and metadata driven engine. Feedback information of each module in the data warehouse and metadata storage will interact on each other. This work constructs a metadata-driven data warehouse system operation mechanism, resolving the difficulties to update and maintain metadata and low efficiency of data quality checking. Finally, it enhances the management and control capabilities of enterprise data warehouse.
