Q&A
Are there only three normal forms?
No, there are more than three normal forms. Additional forms are the Boyce-Codd Normal Form, Fourth Normal Form, Fifth Normal Form/Join-Projection Normal Form. These forms are not often followed because the benefits of doing so are outweighed by the cost in man-hours and database efficiency.
