Good evening to all,

Quick question. Let's say I have the following schema:

R(A,B,C,D)

with FDs:
A->B
B->C
C->D
D->A
AB->C

Question 1:
Would the candidate keys be CK{A,B,C,D,AB}

Question 2:
Would the normal form be BCNF since every determinant is a CK?

Thanks everyone!

TJ

homework alert!!

TJ, we don't do homework assignments, sorry

also, hardly anybody here knows what the heck you're talking about

you can get kick out of school for that

yeah, BCNF is okay.

dont u think {A,B} and {AB} are one and the same? how come uve included both?
