are useful. Because it is an abstract class, it cannot be called directly,

<h4>Description</h4>
<em>Creates a new database object</em><br><small><p>Unlike other objects (Servers, DataObjects, etc.), passing a database
name to the constructor does <em>not</em> pull information from the database.
For example, if you pass an ID to the <code>Server()</code> constructor, it will
attempt to retrieve the information on that server from the service,
and will return an error if it is not found. However, the Cloud
Users service does not permit retrieval of information on
individual databases (only via Collection), and thus passing in a
name via the <code>$info</code> parameter only creates an in-memory object that
is not necessarily tied to an actual database.</p></small><br><h4>Arguments</h4>
