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.

D
Dimensional
Dimensional modeling, particularly the Kimball methodology, offers an alternative approach to data warehousing compared to 3NF, focusing on denormalization for improved query performance.
D
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.
