SQLAlchemy Documentation
SQLAlchemy ORM
Here, the Object Relational Mapper is introduced and
fully described. If you want to work with higher-level SQL which is
constructed automatically for you, as well as automated persistence
of Python objects, proceed first to the tutorial.
SQLAlchemy Core
The breadth of SQLAlchemy’s SQL rendering engine, DBAPI
integration, transaction integration, and schema description services
are documented here. In contrast to the ORM’s domain-centric mode of usage, the SQL Expression Language provides a schema-centric usage paradigm.
