I'm actually uncertain whether you likely consider SQL or Prolog easier. To me both of them have a kind of late seventies feel that is kind of foreign compared to a lot of software stuff from the last quarter of a century.

Pilog is similar to both, the basics are kind of easy to learn, it's basically a bit of Lisp:ish syntax and keywords for 'give me a subset from these sets'. But it's a graph of objects instead of tables or atoms.
