:point_right: 1NF, 2NF ... etc. refer to "Normal Forms".

Normal Forms is a concept of data theory that identifies different levels of database organization. I can't recall if I have seen this discussed in a treehouse course, but here's a Wikipedia page on it and a YouTube video about it.

And here's a Wikipedia page on Functional dependency.

Thank you Steven! :)
