Cube is good for reporting .
If we have huge amount of data and need multidimensional
reporting then for best reporting performance cube is only
solution
Cube allows aggregates and compression which DSO not have .
Cube is good for line item level of data as it provides line
item and high cardinality dimensions.
So use a cube when data amount is large and good reporting
performance is required .
