Сессия базы данных (**`Session`**) хранит **объекты в памяти** и отслеживает любые необходимые изменения в данных, а затем **использует `engine`** для коммуникации с базой данных.

Мы создадим FastAPI-**зависимость** с помощью `yield`, которая будет создавать новую сессию (Session) для каждого запроса. Это как раз и обеспечит использование отдельной сессии на каждый отдельный запрос. 🤓
