    The ORM does it. e.g. ActiveRecord for Ruby on Rails applications, or other ORMs/stacks that work on similar concepts (and there are quite many lately).

    If I see, even Cayenne Modeler supports at generating the DB to skip the creation of FKs. See the second checkbox from the following screen:
