Hello,

in your DEMO program
you got a sample of an ERD.
But for Me it doesn't look like a ERD.


the ERD I know e.g. that thing CHEN created
-->http://en.wikipedia.org/wiki/Entity-relationship_model

I just don't understand the concept behind your kind of ERD.

regard,
Mathias

We did not have in mind any special ERD notation for that sample; it just shows how to create composite entity shapes.

It's a diagram that shows relations between entities, isn't it, so why not call it ERD  8)
