It would be really nice if you could connect to a database from Vertabelo and sync the tables directly.
It could be in a way that it would load the database, generate the diagram and once you change the diagram it would make a change script which you can apply directly from the Vertabelo website to the database itself. (in the best case it would try to apply it and show warning if it would fail)
(2 way syncing between Vertabelo and database)
