For an exam about databases, I have to create a (extended) ER model.
I need a good editor, even if in the worst case I could use CorelDraw or EdgeFlow.
I tried with IBMS, but the kind of notation is not what I want.
I refer to the notation that appears for instance in Elmasri-Navathe's book
(with little circles for the attributes, biforcations for generalizations,
double line for weak entity types, etc.).
If anyone can help me, I'll thank him/her very much! :)
