Today it is possible to manually create an entity diagram, however it would be interesting for some entity diagrams to be created automatically, to facilitate understanding the relationships.
For example, in large projects where there are many entities and we need to delete information, it can become a big problem when we have entities with a "protected" relationship rule.
Because we try to delete and it gives an error, so we do the mapping on the entities' mother and try to create a query to delete.
Perhaps it would be interesting to automatically create entity diagrams for this type of relationship, so when you need to delete some data, just go to the diagram and understand the relationship.
