Question: what are the different steps for finding attributes?
Answer: Find the attribute closures of given FDs R(ABCDE) = {AB->C, B->D, C->E, D->A} To find (B)+ ,we will add attribute in set using various FD which has been shown in table below. We can find (C, D)+ by adding C and D into the set (triviality) and then E using(C->E) and then A using (D->A) and set becomes.
