Bu ayrıca şu anlama da geliyor, bir çok durumda requestten gelen objeyi **direkt olarak database**'e her şeyi otomatik olarak doğrulanmış bir biçimde aktarabilirisin.

Aynı şekilde, databaseden gelen objeyi de **direkt olarak isteğe** de tamamiyle doğrulanmış bir biçimde gönderebilirsiniz.

**FastAPI** ile beraber **Pydantic**'in bütün özelliklerine sahip olacaksınız (FastAPI data kontrolünü Pydantic'in üzerine kurduğu için):
