"At some point, you will need to extract a subset of the relational data and represent it using your application's in-memory model."

...and that is where you have just created an ORM. You don't need a library to be using an ORM. Change 'extract' to 'map' and the meaning is the same.

No, you haven't. If your in-memory application model mirrors your database model, you're probably doing it wrong; either your application model is poor, or your database model is.
