雪花模型在OLAP多维建模中的应用

The Application of the Snowflake Model IN OLAP Multi-dimensional Modeling

简要介绍了OLAP技术的由来及3种常用的OLAP多维数据模型,同时围绕在实际OLAP多维建模中存在的存储空间和性能之间的问题,阐述了用雪花型结构来解决的具体过程。

This paper briefly introduces the origin of OLAP technique and three kinds of common OLAP multidimensional data models, and around the problems between the storage space and the performance existing in actual OLAP multidimensional modeling, expounds the concrete procedures of solving these problems by using the snowflake model.
