What ORMs have taught me: just learn SQL (2014)

That’s just a semantic game. If your language returns the result of a query as a generic array of generic dictionaries (or whatever), that isn’t mapping, nor is it object oriented in principle.

But then your generic array of generic dictionaries needs to be mapped to whatever data structures make sense for your application. ORMs save you that step.

I've written many apps and I've never experienced what you've described. I write my queries to return exactly the right data in exactly the right format in exactly the right order—so I can go straight from the generic data structures to the screen interface or document layout.

Nothing says the structure which make sense for an application can't be a generic array of generic dictionaries.

If your favourite programming language forces you to go through the silly hoops of data mapping in order to do useful things with query output, I can understand why an ORM might make sense for you.
