Session
Managing a database and keeping application data in sync can become complex as Python applications grow. In this hands-on workshop, you’ll learn how to use SQLAlchemy ORM to structure database interactions and build clean, maintainable Python APIs. We will use a commodity pricing API as a practical example to demonstrate how real-world systems are designed.
We’ll cover how SQLAlchemy’s Object Relational Mapper (ORM) replaces scattered raw SQL with structured Python models, making database operations more consistent and easier to manage. Participants will learn how to define ORM classes, model relationships, and work with efficient query patterns.
We will also explore SQLAlchemy’s asyncio extension to show how modern Python applications interact with databases asynchronously.
Participants will leave with practical experience building a working API and a clear understanding of how to structure database-backed Python applications using SQLAlchemy ORM.
