What is 3NF?
3NF stands for Third Normal Form. It is a database normalization level that builds upon the first and second normal forms. A table is in 3NF if it satisfies 2NF and no non-prime attribute is transitively dependent on any candidate key. This means all non-key attributes are dependent only on the primary key.

Dimensional
Dimensional modeling, particularly the Kimball methodology, offers an alternative approach to data warehousing compared to 3NF, focusing on denormalization for improved query performance.
Data Vault
Data Vault modeling provides a different approach to data warehousing that prioritizes auditability and flexibility over the stricter normalization of 3NF.
Kimball
Kimball is a specific dimensional modeling methodology that competes with 3NF data warehousing. It uses a star schema with fact and dimension tables which focuses on denormalization for query speed.
