Functional Dependencies

Functional dependency refers to the relationship between two attributes of a table. This relationship can be used to find the value of one attribute when that of the other is given. It can be mathematically represented as FD: X -> Y. Here, the values of Y are determined by the values of X. X and Y, being the attributes of the table.

Armstrong’s Axioms in DBMS EASY
Armstrong's axioms are a set of references (or, more precisely, inference rules) for inferring all of a relational database's functional dependencies.
Canonical Cover In DBMS MEDIUM
In DBMS, a canonical cover is a set of functional dependencies that is minimal, irreducible, and equivalent to the original set of dependencies. Read on to learn more!
