What’s nice about ActiveRecord is that while it obviously does hook into the Rails object-oriented style, it’s actually more relational and functional than oo in how it works underneath. It’s a fairly thin layer of abstraction over SQL. I think of it more as a way to build and compose SQL statements than a true ORM—at least when it’s used well.
