Q

Are there only three normal forms?

A

No, there are more than three normal forms. Additional forms are the Boyce-Codd normal form, fourth normal form, and 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.
