-- Compatibility DDL section
-- Purpose:
-- 1) make this script usable for both fresh installs and old-environment upgrades
-- 2) absorb historical DDL migration scripts into a single deployment entry
-- 3) keep base-framework tables managed by unisbase itself
--
-- Base framework dependencies not created here:
