What is a Cartesian product?
Here is the answer,
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 EMPLOYEE and STORE tables have 5 rows. If we use a Cartesian join in these two tables, we will get back 25 rows.
