Functional dependency says that if two tuples have same values for attributes A1, A2,, An, then those two tuples must have to have same values for attributes B1, B2, , Bn.

Y, where X functionally determines Y. The left-hand side attributes determine the values of attributes on the right-hand side. Armstrong’s Axioms are a set of rules, that when applied repeatedly, generates a closure of functional dependencies. If alpha is a set of attributes and beta is_subset_of alpha, then alpha holds beta.
