Types of normalizations

Question

Accepted Answer

Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.

Types of normalizations include 1NF, 2NF, 3NF, BCNF, and 4NF.
1NF (First Normal Form) ensures that each column contains atomic values.
2NF (Second Normal Form) eliminates partial dependencies by ensuring all non-key attributes are fully functional dependent on the primary key.
3NF (Third Normal Form) removes transitive dependencies by ensuring that non-key attributes are not dependent on other non-key attributes.
BCNF (Boyce-Codd Normal Form) is a higher level of 3NF that eliminates all non-trivial functional dependencies.
4NF (Fourth Normal Form) further reduces redundancy by eliminating multi-valued dependencies.
