<p>A model represents GDL2s interface to a database. It contains
information required to connect to the database along with entities
and stored procedures.
</p>
<p>All the model classes can be written to and read from property list files
in the form of .eomodel or .eomodeld files. While .eomodel files contain a
model and all its entities and objects in a single property list, .eomodeld files
are a directory with each of the property lists in their own file.
</p>
<p>Typically you won’t create an model through manual instantiation of the classes
but store them in and read them from a property list. We have provided an
example .eomodel file See <a href="Example-model-file.html#Example-model-file">Example model file</a>.
</p>
<p>An EOModel Typically has:
</p><ol>
<li> A Name
</li><li> An adaptor name
</li><li> A connection dictionary
</li><li> An array of entities
</li></ol>
