5NF and Database Design

https://kb.databasedesignbook.com/posts/5nf/wikipedia-1.png
The traditional way of teaching fifth normal form (5NF) is confusing and unnecessary, and a more logical approach is to start with business requirements and create a physical table schema using a textbook table design strategy. Two patterns of physical table design follow naturally: the AB-BC-AC triangle and the ABC+D star pattern, both of which are fully normalized and do not require 5NF ...
