Fifth Normal Form (5NF)

Fifth Normal Form (5NF), also known as Project-Join Normal Form (PJNF), is an advanced level of database normalization that addresses certain types of redundancy not handled by earlier normal forms like Third Normal Form (3NF) and Fourth Normal Form (4NF). It focuses on the representation of relationships between multiple overlapping sets of values within a database schema.

Description:
Fifth Normal Form (5NF) ensures that a database schema is free from join dependencies where information about entities can be inferred by combining information from multiple relationships. It deals with complex scenarios where there are overlapping sets of attributes and ensures that the database schema is structured in a way that prevents anomalies and redundancy.
