maybe when the number of dimension goes to infinity, the joint normal
distribution can converge to the uniform distribution on the unit sphere in
an infinity dimensional space.

5th Dimension - Age of Aquarius
http://www.youtube.com/watch?v=u_zAUrOq-Dc
When the moon is in the Seventh House
And Jupiter aligns with Mars
Then peace will guide the planets
And love will steer the stars
This is the dawning of the Age of Aquarius
The Age of Aquarius
Aquarius! Aquarius!
Harmony and understanding
Sympathy and trust abounding
No more falsehoods or derisions
Golden living dreams of visions
Mystic crystal revelation
And the mind's true liberation

问题还是建这个DW的目的是什么,要用来回答什么样的business question
如果只是要分析这三者的排列组合,和组合出现的次数/几率,join 成 flat table 就
好了
如果一定要建一个DW来分析这个排列组合,那就是三个dimension, DimPerson,
DimRole 和DimDept, Fact table 就是这三个dimension 的key。 最早生成的那个flat

Sector rotation can be performed in 3 dimensions. The first dimension is the

The second dimension is large/mid/small caps. Small-caps outperformed large-

回复
问题一
如果我能在ViewFact里面找到一个CustNo,却在DimAll找不到,是不是说view的query
有问题?或是这个cube根本没法建?
My 2cents -- 应该是view的query 或数据有问题,Fact table 有这个CustNo,
DimensionCustomer 应该要有这个相应的CustNo
问题二
我可以根据DimAll建CustomerStatus的dimension吗?我发现同一个CustNo有多个
CustomerStatus。这个是不是也会有问题?如果可以要怎么做?
My 2cents -- 是同一个CustNo有多个status还是同一CustID 有多个status? CustNo
在这里看来是用来join fact table 和Dimension table 的surrogate key,不能有多

Hi, freeman08, thanks for your input.
I have a couple of follow-up questions.

order".
Regarding this, I am not saying that our physical world is the only
dimension, or realm. Actually I think not, as there are that spiritual
dimension. Souls reincarnate, and they rest there in between, and they
interact with this physical dimension. However, within this physical

己不是科班出身,不太明白怎么回事,所以回来查了一下。
目前我自己的理解是:dimension 越多,需要的数据量就呈几何增长,比如,1-
dimension 需要10个sample的话,2-dimension 就需要 100个, 3-dimension 就需要
1000个,4-dimension 就需要 10000个,...
请问我的理解对么?或者有没有其他含义我没领会到?
谢谢
