Well, I may ask you where you heard that from. Analytical functions
provide "windowing" capability that is either difficult or impossible
to achieve with regular SQL. I would suggest that you read up on the
ORACLE DOC and see what it is all about. With analytical functions you
can calculate aggregates, such as SUM, in many different ways. You can
even massage it so that it gives you the same output as your regular
aggregate SQLs. But it really serves no purpose.
