SQLModel의 `engine` (내부적으로는 SQLAlchemy `engine`)은 데이터베이스에 대한 **연결을 유지**하는 역할을 합니다.

**하나의 단일 engine 객체**를 통해 코드 전체에서 동일한 데이터베이스에 연결할 수 있습니다.

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

`check_same_thread=False`를 사용하면 FastAPI에서 여러 스레드에서 동일한 SQLite 데이터베이스를 사용할 수 있습니다. 이는 **하나의 단일 요청**이 **여러 스레드**를 사용할 수 있기 때문에 필요합니다(예: 의존성에서 사용되는 경우).
