Dimensions
contain a set of unique values that

“The central attraction of the dimensional model of a business is its simplicity....
that simplicity is the fundamental key that allows users to understand databases”
Ralph Kimball, The Data Warehouse Toolkit
Measures
are the main indicators of the
business processes like quantity,
amount, rate, etc.
populate the cells of a logical cube
with the facts collected about
