摘要
针对当前传统数据仓库DB-DW两层体系结构存在的不足,本文引入了ODS(OperationalDataStore)方法,构建起DB-ODS-DW数据仓库三层体系结构;并在分析当前通用数据仓库逻辑建模方法不足的基础上,提出将第三范式(3NF)和星型模式两种建模方法相结合,设计和实现DB-ODS-DW体系结构。
In order to ameliorate the deficiency of currently prevailing data warehouse architecture DB-DW,this paper comes up to build DB- ODS- DW three layer system construction by using ODS Operational Data Store.Then on the basis of analyzing shortcomings of currently general logic modeling this paper combines the Third Normal Form with the star type mode Star Schema to design and accomplish the data warehouse architecture which discussed above.
