True.  Another reason for the term is the network design came
after the relational design.  Frankly, I use the term 
"extended-network".  To me that better conveys the meaning
"we have things (recursive sets, forked sets, many-to-many sets)
that CODASYL networks don't".  By the way, MDBS had to come up
with both these terms (post-relational, extend network) because when we 
invented MDBS III, they didn't exist :-).
