Summary
The article explores the historical reverence for Sixth Normal Form (6NF) in relational database modeling, questioning its perceived impracticality. It argues that any database can be decomposed into 6NF or 4NF, demonstrating the utility of this approach for software developers. The piece aims to simplify the teaching of relational models by removing outdated perspectives.
Key quotes
· 4 pulledOne of the goals of this substack is to research ways of removing historical cruft from the way relational model is taught.
Lots of texts on the internet consider 6NF to be 'exotic', 'academic', 'never used in practice', etc., etc.
As software developers, we can solve any problem by adding one level of abstraction, and database modeling is not an exception.
I’m going to show that any database could be represented as a number of relations in either 6NF or 4NF, and why it’s useful.
