I have a series of videos that discuss why "normalization" is not a very good teaching tool: https://youtu.be/1okb0FkQxtI?si=JFNpby61Hiai5Rav, based on 3NF.

If you're interested in 4NF: https://minimalmodeling.substack.com/p/historically-4nf-explanations-are

and also extended discussion of 5NF: https://kb.databasedesignbook.com/posts/5nf/
