Question 1: Functional Dependencies [7 marks] Consider a relation R on attributes (A, B,C, D, E,F,G, H) and the following functional dependen ACG B C D DE GC DEF H (a) What is the closure of {F, G, H? (b) List al of the candidate keys of R under the dependencies above. (c) List all of the FDs above that are 3NF violations. (d) List all of the FDs above that are BCNF violations. This list will include all of the FDs from part (c), since a 3NF violation is automatically also a BCNF violation
