/// note | 참고

입력 모델은 여전히 검증된다는 점에 유의하세요.

따라서 모든 속성을 생략할 수 있는 부분 업데이트를 받으려면, 모든 속성이 optional로 표시된(기본값을 가지거나 `None`을 기본값으로 가지는) 모델이 필요합니다.

**업데이트**를 위한 “모든 값이 optional인” 모델과, **생성**을 위한 “필수 값이 있는” 모델을 구분하려면 [추가 모델](extra-models.md)에 설명된 아이디어를 사용할 수 있습니다.

We'll fix these things by adding a few **extra models**. Here's where SQLModel will shine. ✨

### Create Multiple Models { #create-multiple-models }

In **SQLModel**, any model class that has `table=True` is a **table model**.

And any model class that doesn't have `table=True` is a **data model**, these ones are actually just Pydantic models (with a couple of small extra features). 🤓

        * **FastAPI**: (uses Starlette) an API microframework with several additional features for building APIs, with data validation, etc.

* **Uvicorn**:
    * Will have the best performance, as it doesn't have much extra code apart from the server itself.
