comment Applying Single Table Inheritance
I've updated my question almost at the same time you answered... Yeah, branches are 1:many to costumers in the previous diagram, I've used a wrong cardinality, sorry! I tried to simplify the database structure in the last diagram, now I think it's more easy to understand what I need... :)
