Hi Ma'm , thank you for explaining so well. I have a question regarding knowing when something is a superkey . You have used a small dataset of which we can then look at it which combinations are possible for SK, but how can we identify or know which combinations SK and how may can be made when dealing with large datasets or something you have been given to create relationships?
