Data mining represents the process of extracting interesting and previously unknown knowledge from data. Functional dependency plays a key role in database normalization. Normalization is process of rectifying database design to make sure that undesirable characteristics do not exist. To discover Functional Dependencies (FDs) from an existing relation instance is an important technique in data mining and database design. Functional dependencies are relationships between attribute of a database relation, a functional dependency state that the value of an attribute is uniquely determined by the values of some other attributes.
