| Question 14 |
Consider the relations r1(P, Q, R) and r2(R, S, T) with primary keys P and R respectively. The relation r1 contains 2000 tuples and r2 contains 2500 tuples. The maximum size of the join r1⋈ r2 is :
| 2000 | |
| 2500 | |
| 4500 | |
| 5000 |
Question 14 Explanation:
r1⋈ r2 is a join operation done on the common attribute R. So this can have 2000 tuples.
Correct Answer: A
