# Generate BigQuery DDL from the Governed Model

Close the loop: meaning goes back where BigQuery users actually read it.

Import your estate, then generate coremodels_bigquery_tables.sql from the governed model: CREATE TABLE IF NOT EXISTS statements with NOT NULL and OPTIONS(description=...) on both columns and tables. BigQuery enforces no keys or CHECK constraints, so governed taxonomies and references are written into the descriptions, never as fake constraints. Generation is a read-only act you run from the landing page; the script goes through code review like any other change.
