# SQL Directory Guide

This project uses Flyway as the single source of truth for schema changes.

## Active SQL

- `src/main/resources/db/migration/*.sql`: production migrations (required)
- `database/init/`: MySQL first-init directory (keep minimal)

## Optional reference SQL

- `database/flowable/`: Flowable engine schema scripts for multiple databases
- `database/upgrade/`: BladeX cross-database upgrade reference scripts

## Cleanup rule

- Do not place full database dumps under `database/` root.
- Keep backups outside repository (off-repo storage or backup system).
