Just looking for some last minute advice for thursday!

In my prelim and all the pastpapers I've done I've struggled a bit with the multi valued attributes. I always seem to understand them AFTER the exam haha, so if anyone could give me some help and advice in relation to understanding them I'd appreciate it!

A multi valued attribute is basically when a cell in a database contains more than one value. For example my full name is Charles Comiskey but if that is put in a cell it will have more than one value. So to make it a single valued attribute you could break my name up into two different attributes which could be Forename and Surname. That would give two single valued attributes. I'm not sure if that is completely right but i hope it can help you.
