Codd's Normal Forms

Codd's Normal Forms are guidelines for organizing data in databases to reduce redundancy and improve integrity. They ensure that data is stored logically and efficiently. Starting from the simplest form, each higher normal form eliminates specific types of issues: the First Normal Form ensures data has no repeating groups; the Second Normal Form removes partial dependencies; and the Third Normal Form eliminates transitive dependencies. Essentially, these standards help create a well-structured database where each piece of data is stored in the right place, making it easier to maintain, update, and retrieve accurate information consistently.
