? A cross join that does not have a WHERE clause produces the Cartesian product of the tables involved in the join.
? The size of a Cartesian product result set is the number of rows in the first table multiplied by the number of rows in the second table.
? Example: is when company wants to combine each product with a pricing table to analyze each product at each price.
