OptionalRelationshipsForeign-key relationships originating from this object (the referencing side). Optional and additive: drivers populate this incrementally as per-provider relationship introspection lands, and DBAutoDoc may further enrich it. An absent or empty array means "relationships not yet discovered", NOT "this object has no relationships".
OptionalSchemaSchema/namespace the object lives in on the remote side, when applicable.
One table/view/collection discovered during schema introspection.
