I have so many questions about that. Should that normal form basically replace 5NF for the purposes of teaching?

Why do they hate us and do not provide any illustrative real-life example without using algebraic notation? Is it even possible?

I just want to see a CREATE TABLE statement, and some illustrative SELECT statements. The standard examples always give just the dataset, but dataset examples are often ambiguous.

Do you understand what are "its" joins? What is even "it" here.

I'm super frustrated. This paper is 14 years old.

I'll try reading it again.
