query technology

I've got a question more theoretical in nature:
Can someone tell me why it is that when I set up a query
on two tables, each with 10 records, and the tables aren't
joined, I get a result with 100 records?

does the engine try to select each record uniquely and
therefore takes every unique combination of records from
the two tables?

thanks,
gordon

Yes, since the tables are not joined, Access is giving you
every combination of the records. It's called a Cartesian
Product.
