You really gave me some food for thought with this:) Yes, you're right. Only difference is normalization. But software differs drastically, guess this is why I percieved these as totally different things.

Thanks for correction.

Not exactly. My preferred model is the model I choose. Just, I don't believe in universal truths:) Like, we have a perfect model named 'theory of everything' that is completelly useless for anything having more than 10 atoms...:)

But needs to be iterated regardless, right? If so, it's not relational.
Please explain; I just don't understand how it can be represented as set.
