I think if you are using an ORM you should know SQL anyway. If you are running into trouble with the mappings it means the the database layout isn't how you are using it in your application.

And that is find when you have more than one application using the database, but, if you are the only one using it, then likely you should change it until it does.

In our team we typically use noSql for databases with single applications, and SQL for ones where we have a lot of applications hanging off the same database.

Just because it means we can match what the application is doing and the database closer.
