============
ORM Examples
============

The SQLAlchemy distribution includes a variety of code examples illustrating
a select set of patterns, some typical and some not so typical.   All are
runnable and can be found in the ``/examples`` directory of the
distribution.   Descriptions and source code for all can be found here.

Additional SQLAlchemy examples, some user contributed, are available on the
wiki at `<http://www.sqlalchemy.org/trac/wiki/UsageRecipes>`_.
