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.
