First Normal Form (1NF) is a property of a relational database table that ensures that the table adheres to certain rules to eliminate redundancy and maintain data integrity. A table is in 1NF if all its columns contain atomic values, meaning each cell holds a single value, and each record is unique, without repeating groups or arrays. This concept is fundamental in designing relational databases as it sets the stage for further normalization and helps improve data retrieval and manipulation efficiency.
