Is this a correct explanation of the first 3 normal forms in database normalization?

I wouldn't say there are any mistakes. The examples are sound. I like the fact that you showed a couple of different ways of doing 1NF.

Normalization doesn't mean "replace values with ID numbers".

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
