in Q 18 , option c can also be correct , as we have to find the age greater than all IT dept students , so we can just select the max age in that dept , and later compare other's ages with that max age

Yes, you are correct. Option (c) is also a valid answer.

Discussion on Question 16: As discussed in the tutorial, Q16 is underspecified and therefore option (d) need not be the correct answer in general. Particularly, if the schemas look like: P(A,B,C), Q(B,C,D) and R(C,D) then although the join of P and Q - denoted as PQ(A,B,C,D) - and the join of P and R - denoted as PR(A,B,C,D) - are union compatible, that does not imply that Q and R would also be union compatible. Additionally, in the context of option (a), the join condition \theta might include attributes from the P(A,B,C), and hence the condition \theta when applied to the join of Q and R might not be valid.

Hi @vijaykiranur856, This revision session was the last problem solving session for the July 2024 offering of the DBMS course. Please note that the questions we were unable to cover during this session have been posted in the google drive and their solutions have been discussed in the earlier tutorials. Hope that helps.
