Crow's Foot Notation

Image 1214

As requested by many of you: SqlDBM adds support for Crow's foot notation! This way users can enhance their understanding of relationship and cardinality/multiplicity between entities. When it comes to relationships between entities, one of the following three relationships can exist between two entities: One to One, One to Many, Many to Many.

I don't see a Cardinality section when  I click on a relationship line, only a prompt to delete the relationship. Is this an Azure Synapse limitation?
