Question
Given two relations S1(A, B) having 3 tuples and S2(C, D) having 2 tuples. The minimum number of tuples possible after the following operation: S1 Right Outer Join S2 a.5b.2c.6d.3
Solution
The minimum number of tuples possible after the operation S1 Right Outer Join S2 would be 2. This is because a right outer join returns all the tuples from the right relation (S2), and the matched tuples from the left relation (S1). If there are no matches, the result is NULL on the left side. Since S2 has 2 tuples, the minimum number of tuples in the result would be 2. So, the correct answer is b.2.
