Hi,
I am working on an assignment which has 2 ternary relationship. I'm
can't figure out their cardinality.
Maybe I am going through one of those mental blocks...
Can someone give me some cardinality examples for N-ary relationships?
all the pics i found on google images don't include this..
My other option is to convert the 3-ary relationship into a weak
entity.. but I'll definitely loose marks on that
Is it ok to have N'ary Relationships which includes recursion? looks
kind of odd to me
eg [person](buyer) trades [item] with [person](seller)
Thanks,
Mike
