SSAS Myths Dispelled
SSAS pre-aggregates data by default
We can emulate in MDX at no cost Enterprise Edition functionality in
Standard Edition
SSAS is always faster than SQL Server RDBMS
MOLAP is always faster than ROLAP
Usage Based Optimizations do not work well
Rigid attribute relationships boost performance
MDX and DAX are hard
