Identify all the candidate keys of the relation.
Identify all the functional dependencies in the relation.
Examine the determinants of the functional dependencies. If any determinant is not a
candidate key, the relation is not well formed. In this case:
Place the columns of the functional dependency in a new relation of their own.
Make the determinant of the functional dependency the primary key of the new
relation.
Leave a copy of the determinant as a foreign key in the original relation.
Create a referential integrity constraint between the original and the new relation.
Repeat Step 3 until every determinant of every relation is a candidate key.
