You can use public link functionality instead of sharing model in such case. You can set it on model details screen.

In Vertabelo we would like to concentrate on ER modeling. Diemensional modeling is not planned.

We don't plan such possibility. It is an element of our current business model. 

Vertabelo supports only crow's foot notation at the moment. Maybe we add others notation in the future, but it is not on our road map now. I leave the question opened, to allow other users vote for it.

There is no n:m relationships because of Vertabelo operates at the physical level, in which such type of relationship doesn't exists. At the physical level n:m relationship is decomposed into two relationships (n:1, 1:m) and a join table. We are planning some microfeatures that can simplify creating such decomposition. 

It is fixed and on the production.

We analyzed this a few months ago and decided not to do. The main problem is related to foreign key naming convention. Every database architect may have own naming convention, so it hard to follow it. 

Thanks for your suggestions. We rethink how to do it better.

You are right. We will fix it soon.

Thanks

It works as described in yours suggestion. When nullable is checked and you check the PK the nullable field is unchecked automatically. 

Did you encounter situation that both nullable and PK were checked at the same time?
