Cube!

When the first I get in touch with BI,I heard about the word 'CUBE'.

But,what's the exact meaning of cube?I have no idear.

Now,I am readind a book about SSAS that written by Chinease and have a little knowledge about CUBE.

We call it '多维数据集', and in my opinion, it's used to analysis data by some kind of dimensions.These dimensions like 'date','product',must be created before we create the 'cube'.

we can create the dimensions by the SSAS.I will talk abput the specific method of create the dimension later.
