### Criar um Engine { #create-an-engine }
Um `engine` SQLModel (por baixo dos panos, ele é na verdade um `engine` do SQLAlchemy) é o que **mantém as conexões** com o banco de dados.

Você teria **um único objeto `engine`** para todo o seu código se conectar ao mesmo banco de dados.

### Engine Oluşturma { #create-an-engine }

Bir SQLModel `engine`’i (altta aslında bir SQLAlchemy `engine`’idir) veritabanına olan **bağlantıları tutan** yapıdır.

Tüm kodunuzun aynı veritabanına bağlanması için **tek bir `engine` nesnesi** kullanırsınız.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}

    SQLModel знатиме, що оголошене як `str` стане SQL-стовпцем типу `TEXT` (або `VARCHAR`, залежно від бази).

### Створіть рушій { #create-an-engine }

`engine` SQLModel (під капотом це `engine` SQLAlchemy) - це те, що **утримує з’єднання** з базою даних.

У вас має бути **єдиний об’єкт `engine`** для всього коду, що під’єднується до тієї самої бази.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}
