摘要
针对当前流行数据仓库体系DB DW存在的不足,引入ODS,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(ThirdNormalForm,3NF)和星型模式(Star Schema)两种建模方法相结合来设计和实现DB ODS DW体系。
In order to ameliorate the deficiency of currently prevailing data warehouse architecture DBDW,this paper comes up to build DBODSDW three layer system construction by useing 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(StarSchema)to design and accomplish the data warehouse architecture which discussed above.
