Another good point. Truth be told, I’m not too familiar with the compression mechanism for SSAS data. Do you have any recommended reading?

A good point although a date data type without the time portion should compress equally well.

Teo – very interesting. One thing probably worth mentioning is that SSAS doesn’t support the DATE data type and will convert it to System.Datetime which is internally stored as a double (8 bytes). On the other hand, the INT data type is stored as System.Int32 (4 bytes).
