Inklusive externer Bibliotheken, die auf Pydantic basieren, wie <abbr title="Object-Relational Mapper (Abbildung von Objekten auf relationale Strukturen)">ORM</abbr>s, <abbr title="Object-Document Mapper (Abbildung von Objekten auf nicht-relationale Strukturen)">ODM</abbr>s für Datenbanken.

Including external libraries also based on Pydantic, as <abbr title="Object-Relational Mapper">ORM</abbr>s, <abbr title="Object-Document Mapper">ODM</abbr>s for databases.

This also means that in many cases you can pass the same object you get from a request **directly to the database**, as everything is validated automatically.

Wliczając w to zewnętrzne biblioteki, również oparte o Pydantic, takie jak <abbr title="Mapowanie obiektowo-relacyjne. Po angielsku: Object-Relational Mapper">ORM</abbr>, <abbr title="Object-Document Mapper">ODM</abbr> dla baz danych.

Oznacza to, że w wielu przypadkach możesz przekazać ten sam obiekt, który otrzymasz z żądania **bezpośrednio do bazy danych**, ponieważ wszystko jest walidowane automatycznie.

Bunlara Pydantic üzerine kurulu <abbr title="Object-Relational Mapper">ORM</abbr> databaseler ve , <abbr title="Object-Document Mapper">ODM</abbr> kütüphaneler de dahil olmak üzere.

/// tip

You could use any other SQL or NoSQL database library you want (in some cases called <abbr title="Object Relational Mapper, a fancy term for a library where some classes represent SQL tables and instances represent rows in those tables">"ORMs"</abbr>), FastAPI doesn't force you to use anything. 😎
