Explanation

1NF (First Normal Form) is considered the automatic or default normal form because it requires only basic atomicity and no repeating groups. Higher normal forms (2NF, 3NF, 4NF) require additional constraints about functional dependencies and multivalued dependencies that must be explicitly designed.
