SQLAlchemy is the Python SQL toolkit and Object Relational Mapper thatgives application developers the full power and flexibility of SQL.

It provides a full suite of well known enterprise-level persistencepatterns, designed for efficient and high-performing database access, adaptedinto a simple and Pythonic domain language.

SQLALCHEMY'S PHILOSOPHY

SQL databases behave less like object collections the moresize and performance start to matter; object collections behave less liketables and rows the more abstraction starts to matter. SQLAlchemy aims toaccommodate both of these principles.

SQLAlchemy considers the database to be a relational algebra engine, not just a collection of tables. Rows can be selected from not only tables but also joins and other select statements; any of these units can be composed into a larger structure. SQLAlchemy's expression language builds on this concept from its core.

SQLAlchemy is most famous for its object-relational mapper (ORM), an optional component that provides the data mapper pattern, where classes can be mapped to the database in open ended, multiple ways - allowing the object model and database schema to develop in a cleanly decoupled way from the beginning.

SQLAlchemy's overall approach to these problems is entirely differentfrom that of most other SQL / ORM tools, rooted in a so-called complimentarity-oriented approach; instead of hiding away SQL and object relational details behind awall of automation, all processes are fully exposed within a series of composable, transparent tools. The library takes on the job of automating redundant tasks while the developer remains in control of how the database is organized and how SQL is constructed.

The main goal of SQLAlchemy is to change the way you think about databasesand SQL!
