What is Cardinality?

27 Views

Hi,

Can i know the difference in Cardinality and Selection.

There are altogether four different Combinations:

0..1,0..n,1..1 and 1..n.

So ,if anyone could explain me clearly about all these four Combinations it would be appreciated.

Also if i could know more about these properties it would be easier for me to work on different applications.

Thanks and regards,

Chandrashekar.
