I have heard that some systems still use 2NF for specific reasons.

I believe BCNF is also a good choice for database normalization.

Wait, what's normalization again? Is that the thing where you make your database super complicated so that no one can use it? Sounds like a great idea!

Hmm, I'm not so sure. I've heard BCNF is the way of the future. Gotta future-proof that database, you know? 3NF is so last decade.

Yeah, 3NF is definitely the way to go. I mean, who needs all that BCNF complexity, am I right? Just keep it simple, you know?
