What does 2NF stand for?

Second Normal Form

The abbreviation 2NF stands for Second Normal Form in computing, especially in the field of database design. Second Normal Form is a level of database normalization that helps organize data to reduce redundancy and improve data integrity. A table is in 2NF if it is already in First Normal Form (1NF) and all non-key attributes are fully dependent on the entire primary key. People searching for “2NF database,” “Second Normal Form example,” or “database normalization levels” are looking for ways to make their data storage more efficient and organized.

Applying 2NF helps database designers avoid duplicate data and update anomalies, making databases easier to maintain and query. It’s a key concept for students and professionals working with relational databases and structured data.
