There are lots of relational databases today; MySQL, Postgres, Oracle etc. But IBM's System R established the pattern in 1974, and later IBM products SQL/DS and DB2. And of course their competitor, Oracle. OpenClaw might not have been the absolute exact first, but it did establish the pattern and is the head of the family tree of modern agents, stretching back, oh, about 7 months now. Of course there will be better architectures. Functional AI Agents deployable at home didn't exist a year ago.
