Dive into SQLAlchemy, the popular, open-source code library that helps
Python programmers work with relational databases such as Oracle, MySQL,
PostgresSQL, and SQLite. Using real-world examples, this practical guide
shows you how to build a simple database application with SQLAlchemy,
and how to connect to multiple databases simultaneously with the same
metadata.
SQL is a powerful language for querying and manipulating data, but itâ s
tough to integrate it with your application. SQLAlchemy helps you map
Python objects to database tables without substantially changing your
existing Python code. If youâ re an intermediate Python developer with
knowledge of basic SQL syntax and relational theory, this book serves as
both a learning tool and a handy reference.
Essential SQLAlchemy includes several sections:
SQLAlchemy Core: Provide database services to your applications in a
Pythonic way with the SQL Expression Language
SQLAlchemy ORM: Use the object relational mapper to bind database
schema and operations to data objects in your application
Alembic: Use this lightweight database migration tool to handle
changes to the database as your application evolves
Cookbook: Learn how to use SQLAlchemy with web frameworks like Flask
and libraries like SQLAcodegen
