If you are talking about setting up a o-o relationship, then yes
EOmodeler will do this. Create the two tables, ctrl-drag from the
primary key in one to the PK in the other and in the resulting window,
click "to one".
I suspect you are, though, asking a more complex question. If you are,
perhaps you can clarify with an example.

Does anyone know if EO Modeler supports a one-to one relationship

I've been trying to set up my EOModel like this for a while now, but
no matter which way I try to do it EO Modeler complains.
A use case of this would be if you have a single data object, linked
to its corresponding single state object. In O-O you would want to
keep the logic handling these separate. (I.e. 2 different classes)
I ended up working around this so its not a showstopper for me but I'm
just curious for future reference if anyone's actually managed to do
it, and if so how.
thanks
