Hi.

I am tuning a query that runs against a star schema and a few dimension tables. The plan shows that the first step is two join two dimension tables via a cartesian join. Why would Oracle does that instead of joining the dimensions to the fact table one after another? Can anyone offer an explanation?

thank you
