http://en.wikipedia.org/wiki/Fact_table|||Remember the Rubic's Cube puzzle toy? Picture that as your OLAP cube. Each
colored square represents a cell. One row in your fact table becomes a cell
in your cube for a given measure.
It is the lowest level of detail and thus gives the ability to roll-up
values (aggregate) at various dimensional levels.
