Training goals

code: PA-SQLA

SQLAlchemy is THE object relational mapper used in the Python world. It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.

This practical course will make sure you understand the concepts behind SQLAlchemy. We will focus on practical patterns of SQLAlchemy usage and see how its use can grow from very simple to more advanced.
