SQL Developer Data Modeler

Hi,

I’m currently at a client where we’re using Oracle SQL Developer Data Modeler to design our Logical Data Models (as part of an overall deliverable).

When in the Oracle SQL Developer Data Modeler (in the logical view), I’m trying to figure out if the tool has the ability to create a “zero or one to” relationship between entities.

According to the relationship options available, it only seems to show:
One to One,
One to Many (*),
Many (*) to One, or
Many (*) to Many (*)


In the preferences – Data Modeler – Diagram – Logical Model, the notation type is set to “Barker”.

I don’t see anywhere else where configuration can affect the variation of these options…


Is there a way to show either a “Zero or One to…” relationship between entities?


I’ve also loaded version 3.1 (beta) and it appears to be behaving the same as 3.0…


Any insights are greatly appreciated…



Thanks,

Patrick
