Multivalued dependency

In general, a multivalued dependency occurs when a relation R has attributes A, B, and C such thatA determines a set of values for B, A determines a set of values for C, and B and C are independent of Read More …

Partial dependency

A functional dependency that holds in a relation is partial when removing one of the determining attributes gives a functional dependency that holds in the relation.Eg if {A,B} → {C} but also {A} → {C} then {C} is partially functionally Read More …

Full functional dependency

An attribute B is fully functionally dependent on A if the B can be determined by whole of A not by any proper subset of A. A functional dependency X → Y is a full functional dependency if removal of Read More …

Functional Dependency

Normalization is based on the concept of functional dependency. A functional dependency is a type of relationship between attributes.Attribute of set of attributes on the left side are called determinant and on the right are called dependentsLike R (a, b, Read More …
