Hi Zeyi ,

I was just wondering how you calculated that each dimension table in scenario C for the example you ran through in lecture 4 would have 60,000 possible rows? 

Wouldn't it be possible for a dimension to have 100 million unique values if there are 100 million facts in the fact table? How can you be certain there would be only 60,000 possible values for each dimension, or is that simply an assumption?
