Hi All,

I've been taking a look at DB Designer 4, and looking through the 
documentation (http://www.fabforce.net/dbdesigner4/doc/index.html) I am a 
little unclear on some of their nomenclature:

'1:1' - Ok, one to one.  Got it.
'1:1' generalization - Don't know this.  Obviously different somehow from 
one to one, but how?
'1:n' - One to many, I assume.
'1:n non identifying' - Nonidentifying?  What does this mean?
'n:m' - Many to many?  Again, not sure.

Can anyone help clarify?

Thanks!
  -Josh
