There are many different ways to provide this functionality to your application. Below are a few examples.

Basic setup

The adapter can then be accessed in any ServiceLocatorAware classes.

More information on adapter options can be found in the docs for :ref:`Zend\\Db\\Adapter <zend.db.adapter>`.
