Database normalization - Wikipedia
Database normalization is the process of structuring a relational database accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity. It was first proposed by British computer scientist Edgar F. Codd as part of his relational model .

Sep 15, 2023 · The most commonly used normal forms are: First Normal Form (1NF): Ensures that each column in a table contains atomic, indivisible values. There should be no repeating groups, and each column should have a unique name. Second Normal Form (2NF): Building on 1NF, 2NF eliminates partial dependencies.
