간단한 예시를 위해 [더 큰 어플리케이션 만들기](../ko/tutorial/bigger-applications.md){.internal-link target=_blank} 와 [테스트](../ko/tutorial/testing.md){.internal-link target=_blank}:에서 다룬 파일 구조와 비슷한 형태를 확인해봅시다:

**SQLModel** построен поверх <a href="https://www.sqlalchemy.org/" class="external-link" target="_blank">SQLAlchemy</a> и Pydantic. Его создал тот же автор, что и **FastAPI**, чтобы он идеально подходил для приложений FastAPI, которым нужны **SQL базы данных**.
