## What it is
Tortoise ORM is an asyncio-native Object Relational Mapper for Python with a Django-inspired API, supporting SQLite, PostgreSQL, MySQL, SQL Server, and Oracle. It provides model definitions, relations, queries, and schema migrations for async Python applications.

## Use cases
- use an async ORM for a FastAPI backend
- define database models with relations in asyncio Python
- migrate from Django ORM to an async stack
- query PostgreSQL without writing raw SQL in async code
- manage schema migrations for an async Python app
- benchmark-friendly ORM for high-throughput database reads and writes

## When to choose
- your application is asyncio-based and needs database access
- you want a Django-like model and query API in async Python
- you need support for multiple relational databases including PostgreSQL and MySQL
- you want a lightweight ORM with good performance

## When to avoid
- you need a fully synchronous ORM like Django ORM or SQLAlchemy sync
- your project requires long-term API stability, as breaking changes are expected
- you need NoSQL or non-relational database support
- you rely on Python versions older than 3.10
