I think this is broadly true, but there's also a subset of DOD design advice (e.g. see Richard Fabian's book) that has a lot to say about relational database design. In our team it's provided us with some very practical motivation for more normalised table designs. Doing 1+n requests to the database due to poor implementation feels similar now to pointer chasing.

The connection is that ORMs convince you to have an object-oriented view of the world, which maps nicely to object classes. But highly normalised designs don't map as cleanly to classes and objects, so you need to approach with a different style of programming on the application side.

Instead of seeing a User instance, you start to see a more complex bundle of login methods, profile events, etc.
