WebFunctional Dependencies and Normalization Database Design @Griffith University, Australia 2. Relationship between FDs and keys in a relation A set X of attributes in R is a superkey of R if and only if X+ contains all attributes of R. In other words, X is a superkey if and only if it determines all other attributes. WebFunctional dependency (FD) is a set of constraints between two attributes in a relation.
