Hi,
I've got to make an exam about database systems tomorrow, and i'm practicing with an old exam now.
But i'm not sure about this question that i have to answer true or false:
The attributes of a candidate key always form a proper subset of a Superkey.

So i was wondering of someone here can say if this statement is true or false :)

p.s. I'm not sure if i translated it right but i think so:redface:

What is it in Dutch? I'm assuming you're dutch.

In dutch:
De attributen van een candidate key vormen altijd een strikte deelverzameling van een superkey.

waar of onwaar ;)

I've had my exam today, so this can be locked ;)
The answer to my question was false (Asked another student, If anyone would like the explanation you can pm me).
Thanks for looking in to this, despite nobody could answer my question :)

Yeah, sorry. Villavu forced me to change my password and I didn't have time to do so yet, so I didn't look at this thread again. :p

If you still want an answer for this, it would be a good question for one of the StackExchange sites - you could try the DBA site
