# Database

EF Core owns the current schema and migrations. SQLite is the local default; MariaDB/MySQL is supported for server deployments.

- [Schema overview](schema.md)
- [Migrations and compatibility](migrations.md)
- [Backups](backups.md)
- [Database ownership in the architecture](../architecture/overview.md)

Never reset a development or production database as part of documentation work. Use disposable test databases for migration checks.
