Except files are modelled. You have a bunch of functions for finding the right one, then a bunch for manipulating files at rest, then a few for giving you a file descriptor. The file descriptor represents the file in your language and is the equivalent of parf of what some ORMs do. It's an explicit interface between external data and your program, just like a good SQL library (like SQLAlchemy).
