The first semantic-gravity engine

Related data should live together.

And in xyzDB it does: let things that mean the same fall together and a query stops chasing tables — it becomes a single read, even filtered to one customer or one agent. You just say what goes with what; the engine decides where each record lands on disk, and everything else — relating, indexing, aggregating — resolves on top of that placement. Fifty years sorting data by type; this one sorts it by meaning.

Six sections, left to right. Each one goes a level deeper.
