What does 1NF stand for?

First Normal Form

The abbreviation 1NF stands for First Normal Form in computer science, especially in database design. First Normal Form is a basic rule for organizing data in relational databases to ensure that each column contains only one value and each row is unique. By following 1NF, database designers eliminate repeating groups or arrays within tables, making the data easier to search, update, and maintain. People searching for “1NF in database,” “First Normal Form example,” or “database normalization” are interested in keeping data well-structured and efficient.

Applying 1NF is the first step toward reducing data redundancy and improving consistency in a database. This concept is important for anyone working with relational databases, from students learning the basics to professionals building complex systems.
