Connecting FastAPI to PostgreSQL
Set up a connection between your FastAPI application and a PostgreSQL database using SQLAlchemy.
Why Connect to a Database?
Web applications often need to store and retrieve data persistently. This data could be user profiles, product listings, or transaction records.
Instead of losing data when your app restarts, we connect to a database. Databases provide a structured and efficient way to manage large amounts of information.
Introducing PostgreSQL
PostgreSQL is a powerful, open-source relational database system. It's known for its robustness, feature set, and performance.
- Reliable: Ensures data integrity.
- Scalable: Handles large data volumes and high user loads.
- Extensible: Supports custom data types and functions.
Many FastAPI applications use PostgreSQL as their primary data store.
