Thanks guys for all your inputs. This is the correct solution: To prove R1(A,B,C,D), R2(C,D,E,F), R3(E,F,G,H) are all in BCNF, compute the closure for all possible subsets of Ri. • For R1(A,B,C,D) • Closures of attribute sets: – (A)+ F = A – (B)+ F = B – (C)+ F = C – (D)+ F = D – (AB)+ F =...

Sure :) Well, the course is called Introduction to Databases so my guess is it's not supposed to be very advanced ;).

Hello there I am having a tough time figuring out how to do one of the questions on my assignment. Given schema R with attributes {A,B,C,D,E,F,G,H} and functional dependencies: { G->B AB->D DE->C GF->H BD->E AH->F CE->A AD->H GF->D } I have to prove that the following decomposition...
