Hi,
While I was trying to make an Anchor model in SDDM to show in my blog post http://www.datadenken.nl/2015/12/14/build-an-anchor-model-with-oracle-sql-developer-modeler-4-0-sddm/ I created a three way tie that has only 2 unique constraints.
I could not create it in the Anchor modeling tool. Is there a way to do this?

JJ.
The way cardinalities and uniqueness is specified for ties will have to be reworked in the tool. We added an issue about it on GitHub a while back.
https://github.com/Roenbaeck/anchor/issues/1
It is currently at the top of my TODO-list, so with a bit of luck it may be in the tool after the holidays. I will also be adding a presentation on cardinality held at the University to the Publications section soon.
Hi Lars,
I was thinking about a way to add the possibility to model a unique constraint over more than 1 role in the modeler tool. I've made a picture with yEd to show the construct:
Is this a way to visualise it, do you think?
Regards,
JJ.
