The difference between 3NF and BCNF . is that for a functional dependency A ( B, 3NF allows this dependency in a relation if B is a primary-key attribute and A is not a candidate key, whereas BCNF insists that for this dependency to remain in arelation, A must be a candidate key. 3. What is the different between super key and candidate key ?

The functional dependency Pk(account) → Pk(customer) indicates a many to-one relationship since any account value which is repeated will have the same customer value, but many account values may have the same customer value. ... Therefore R is a 3NF dependency-preserving lossless-join decomposition.

The table must be in 3NF. Every non-trivial functional dependency must be a dependency on a superkey. Example of the Process. The following example illustrates how a database designer might employ his knowledge of the normal forms to make progressive improvements to an initially unnormalized database design. The example is somewhat contrived ...

Functional Dependency: Attribute B is functionally dependent on Attribute A, (or group of attributes A) if for each value of A there is only be one possible value of B. We say A---> B (A decides B) or (B is functionally dependent on A). ... (3NF) is a normal form used in database normalization. 3NF was originally defined by E.F. Codd in 1971.[1]
