Solution
The operation that contains all pairs of tuples from the two relations, regardless of whether their attribute values match, is the Cartesian product.
Here's a step-by-step explanation:
- In relational database theory, a Cartesian product is a mathematical operation that returns a set from multiple sets.
- In the context of SQL, it's a product operation between two tables (relations).
- The result of a Cartesian product (also known as a cross-join) is a table that combines each row from the first table with each row from the second table.
- This means that it will return all pairs of tuples, regardless of whether their attribute values match.
