I think you're right. Probably due for a follow-up post. EDIT: what was the system, by the way?

  Standard Chartered Bank's in-house Haskell dialect (and supporting libraries). Codd's original paper about how relational databases are more flexible than hierarchical databases applies just as well when comparing relations against key-value stores like Python's dictionaries (or Haskell's Data.Map, or 'normal' ways to structure data in applications, which can be seen as the equivalent of statically typed dictionaries.)

    Yes! I dream of a language were the relational table is the primary data structure.

      Oh, it wasn't a primary data structure, yet alone 'the' primary data structure. It was just provided via a library and very easy to use. Haskell is pretty good about making user-provided libraries as convenient to use as things built into the language.

      These are not programming languages per se, but give VDM-SL or Alloy Analyzer a look. I know that particularly in the latter, anything can be joined or composed against anything since all values are relations.
