Pivot tables can be populated from another worksheet, a data source, an OLAP 
cube, etc...

That number is pretty high these days, but yes there is no point using an 
intermediary worksheet. Get the data directly from source. Also, you may want 
to pre-process, e.g. summarize, your data in the database already as much as 
you can before hand. Excel is not a speed daemon when confronted with a truck 
load of data.

You can also create and save the pivot table as an offline OLAP cube, with 
hierarchical dimensions & all (Microsoft Query + OLAP Cube Wizard).
