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

Объект `engine` в SQLModel (под капотом это `engine` из SQLAlchemy) **удерживает соединения** с базой данных.

У вас должен быть **один объект `engine`** для всей кодовой базы, чтобы подключаться к одной и той же базе данных.

Network isolation between different models is also important not only to prevent
unauthorized access to data or models, but also to prevent malicious users or
tenants sending graphs to execute under another tenant’s identity.

The isolation mechanisms are the responsibility of the users to design and
implement, and therefore security issues deriving from their absence are not
