Discussion
_______ produces the relation that has attributes of R1 and R2
Answer: A
Correct answer: Cartesian product
The Cartesian product \(R_1 \times R_2\) pairs every tuple of one relation with every tuple of the other, so the result has all the attributes of both and \(m \times n\) tuples. Difference and intersection require the two relations to be union-compatible and produce no new attributes at all.
