Repeat Exercise 10.26 for the following different set of functional dependencies
G = HA, B} -7 {C}, {B, D} -7 {E, F}, {A, D} -7 {G, H}, {A} -7 {l}, {H} -7 {l}}.
Consider the following relation:
a. Given the previous extension (state), which of the following dependencies
may hold in the above relation? If the dependency cannot hold, explain why by
specifying the tuples that cause the violation.
i. A B, ii. B C, iii. C B, iv. B A, v. C A
b. Does the above relation have a potential candidate key? If it does, what is it? If
it does not, why not?
