Question
Consider two database relations T1 and T2 having 5 and 2 tuples respectively. What is the maximum number of tuples that could appear in the natural join of R and S?a.7b.5c.10d.2
Solution 1
The maximum number of tuples that could appear in the natural join of T1 and T2 is determined by the smaller number of tuples in either relation. In this case, T2 has the smaller number of tuples, which is 2. Therefore, the maximum number of tuples that could appear in the natural join of T1 and T2 is 2. So, the correct answer is d.2.
Solution 2
The maximum number of tuples that could appear in the natural join of T1 and T2 is determined by the smaller number of tuples in either relation. In this case, T2 has the smaller number of tuples, which is 2. Therefore, the maximum number of tuples that could appear in the natural join of T1 and T2 is 2. So, the correct answer is d.2.
