<h2>Overview</h2>
<p>Methods that are shared accross session like objects:</p>
<ul><li>Database</li><li>Connection</li></ul></ul>
<p>Classes that includes this module are able to execute
queries and statements in both prepared and unprepared fashion.</p>
<p>This module serves for dsl reuse over session like objects.</p>
