Key field
Hi, I am preparing for an exam and am working through some past exam papers.
There is a questions that says "show how a key field is used in a relational database across three (3) database tables". I am assuming that the key field they refer to is the primary key, but how does it go across 3 tables? I hope someone can shed some light on this for me, in case a similar question comes up :-) Many thanks. -- Trish
