# Database Engines

Database engines allow you to work with tables. By default, ClickHouse uses the [Atomic](../../engines/database-engines/atomic.md) database engine, which provides configurable [table engines](../../engines/table-engines/index.md) and an [SQL dialect](../../sql-reference/syntax.md).

Here is a complete list of available database engines. Follow the links for more details:

- [Atomic](../../engines/database-engines/atomic.md)

- [Lazy](../../engines/database-engines/lazy.md)

- [Replicated](../../engines/database-engines/replicated.md)

- [PostgreSQL](../../engines/database-engines/postgresql.md)
  
- [MySQL](../../engines/database-engines/mysql.md)

- [SQLite](../../engines/database-engines/sqlite.md)

- [MaterializedPostgreSQL](../../engines/database-engines/materialized-postgresql.md)
  
- [MaterializedMySQL](../../engines/database-engines/materialized-mysql.md)
