Augmenter Databases
===================

.. module:: pyrseas.augmentdb

The :mod:`augmentdb` module defines :class:`AugmentDatabase`.

Augmenter Database
------------------

An :class:`AugmentDatabase` is derived from
:class:`~pyrseas.database.Database`.  It contains two "dictionary"
objects.

One is the :class:`Dicts` container from its parent class. The `db`
Dicts object, defines the database schemas, including their tables and
other objects, by querying the system catalogs.

The second container is an :class:`AugDicts` object.  The `adb`
AugDicts object specifies the schemas to be augmented and the
augmenter configuration objects.  The latter objects may be supplied
either by other Augmenter modules or from the 'augmenter'
configuration tree on the `aug_map` supplied to the `apply` method.
