This. I'm continually amazed how many people think they will only ever have one application talking to their database. Unless your project promptly crashes and burns, you're going to find yourself using tools in different languages, and it's going to be incredibly painful not to have invested in competent data modelling that avoids relying on some specific ORM.

I repeat: Red Herring. Competent data modeling and AR migrations are in no way related.

Moreover most grown up applications consist of multiple database, since it would be unwise to mix e.g. reporting concerns into a webapp database schema.
