One feature that we feel is a bit missing is the cardinality information on the joins (0,1,n), it does help in the visibility of the diagram.
We are glad you created this "Idea" ticket. We will discuss it with our team and work on it, in case there are lot of user votes for this.
Thank you for your assistance,
is there any update to adding this feature? I'm staring at a data model I created, I feel it's hard for someone else to look at it and understand the relationships without seeing the cardinality of the relationship.
this feature is not yet implemented, you can see our roadmap here https://sqldbm.com/RoadMap/
