How can I show non-transferability in a relation. Normally you would do that with a diamond I believe.

It depends which notation you are using.  ModelRight supports three different modeling notations - IE, Barker (Orace-CASE) and IDEF1X.  To change the notation, select the diagram in the Model Explorer, then go to the Notation tab in the Property Browser - or change the default Diagram domain's notation setting to affect all diagrams.

Then, select the relation, and look at its Integrity tab to set the Mandatory or Nulls Allowed property.

Scott,

I use the Barker notation and of course I saw the possibilities of mandatory and (not)null but that is not waht I mean. Non-tranferability means that one instance cannot be replaced with another instance. A prescription for a patient cannot be moved on to another patient, you may not transfer it. That is different from NULL or mandatory.

I follow a course with Oracle. We have to do homework and I started drawing my homework with ModelRight. I donwloaded a trial version but I am very happy with it.So far I managed to draw everything, but now Ineed to place a diamond on a relation when that relation is non-tranferable. I can of course use the polygone.

I am a teacher at a secondary school in the Netherlands. What would it cost if I want to buy ModelRight, just for me. Not for all the students. I would like to install it on my desktop and on my laptop. I need the Oracle Barker notation, nothing else.

Oh.  I see.  No, we don't explicitly support that.  You would have to draw with a polygon.  We do offer significant discount for educational/non-profits.  I'll have someone from sales get in touch with you with details.  Thanks.
