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.

This includes, for example:

* Email notifications sent after performing an action:
    * As connecting to an email server and sending an email tends to be "slow" (several seconds), you can return the response right away and send the email notification in the background.
* Processing data:

			b.updateXferRate(rs.TransferSize, rs.TransferDuration)
		}
	case rs.Failed:
		b.FailStats.addsize(rs.TransferSize, rs.Err)
	case rs.Pending:
	}
}

	// transfer size
	TransferSize int64
	// transfer duration
