SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. 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. It includes both a Core SQL toolkit (connections, schema management, SQL expression language) and an Object Relational Mapping (ORM) layer, with dialect support for multiple database backends.
