Dimensionality is the key to OLAP
Multidimensionality allows users to analyze data across multiple axes
A 5 dimensional cube includes time, products, customer, salesperson, and measures
Within each dimension are ÅglevelsÅh or hierarchies that organize the dimension members
A time hierarchy might be: years, quarters, and months
OLAP allows users the ability to look at any intersection among the dimensions
