Which databases can the schema architect target?

Choose PostgreSQL, MySQL, or MongoDB. PostgreSQL and MySQL results contain CREATE TABLE-oriented DDL; MongoDB results provide collection schema definitions and reference guidance rather than SQL DDL.

Why does every result include a Mermaid ER diagram?

The contract requires an ER diagram beginning with erDiagram so entities and relationships can be reviewed visually alongside the database-specific schema.

How are index recommendations selected?

The assistant is required to return at least one recommendation with a table or collection, columns or fields, and a reason. Treat these as query-driven proposals and confirm them against real filters, joins, sorts, and uniqueness requirements.

Is the generated DDL safe to run in production?

No. Review data types, constraints, locking, naming, permissions, migration and rollback strategy, tenancy, and retention. Test the script in a disposable environment before applying it to production.
