### Minimal Database
This feature organizes base data into smaller, modular structures for PostgreSQL and SQLite databases:
- **SQLite**: Each base's data is stored as a separate SQLite file, ensuring isolated storage.
- **PostgreSQL**: A unique schema is created for each base, providing logical separation within the database.
**Note**: For PostgreSQL, this feature is enabled by default if the user has the required permissions. To disable it, set the `NC_MINIMAL_DBS` environment variable to `false`.
