Thanks.

Not quite sure of the relevance of this question.

Ah, I was researching elemenTARTY keys, probably why I got it wrong

Life: it twists and turns like a twisty turny thing

I said C only: Some other attribute B is fixed by a set including A but by no subset of that set - which is clearly true.

Couldn't get the other two parts though. I guess I join the 98% of answerers that aren't database professionals.

Thanks for the question.


Please don't go. The drones need you. They look up to you.

Comments posted to this topic are about the item <A HREF="/questions/Normalisation/74786/">Elementary Key Attributes</A>

I find it quite frightening that so few people know enough about normalisation to get this one right.

My only comment is that there is no identifier (per other QOTD's) of how many answers to answer... I got 2 out of 3 but still marked as wrong.

I got two out of three, which is okay with me.

Of all of my skills and talents, the ability to recite every obscure factoid about relational databases (or any other software system or process) is not at the very top of the list. That place is reserved for critical thinking, analysis and application of experience and creativity to solve problems effectively.




The probability of survival is inversely proportional to the angle of arrival.
