Answer / eng-wael
The Cartesian product, also referred to as a cross-join, returns all the rows in all the tables listed in the query. Each row in the first table is paired with all the rows in the second table. This happens when there is no relationship defined between the two tables. Both the AUTHOR and STORE tables have ten rows. If we use a Cartesian join in these two tables, we will get back 100 rows.

have a specific need to combine all rows from all tables.
