In general, a multivalued dependency occurs when a relation R has attributes A, B, and C such that

A determines a set of values for B, A determines a set of values for C, and B and C are independent of each other.

We write this as

A –>> B and A –>> C

The formal definition of multivalued dependency is:

Definition. X –>> Y is a multivalued dependency if

If t1 and t2 are tuples such that t1.X = t2.X, then there are tuples t3 and t4 such that

1. t1.X = t3.X = t4.X 2. t1.Y = t3.Y and t2.Y = t4.Y 3. t1.Z = t4.Z and t2.Z = t3.Z

where Z = R – (X U Y)
