The normalization of a data cube is the process of choosing an ordering for the attribute values, and the chosen ordering.Our optimized hybrid OLAP storage mechanism was observed to be 44% more storage efficient than ROLAP and the gains due to normalization alone accounted for 45% of this increase in efficiency.
