 The architecture of a CDO application is characterized by its mandatory dependency on EMF, the Eclipse Modeling
 Framework. Most of the time an application interacts with the object graph of the model through standard EMF APIs
 because CDO model graph objects are <a href="http://download.eclipse.org/modeling/emf/emf/javadoc/2.7.0/org/eclipse/emf/ecore/EObject.html" title="Interface in org.eclipse.emf.ecore"><code>EObjects</code></a>. While CDO's basic functionality integrates nicely and
 transparently with EMF's extension mechansims some of the more advanced functions may require to add direct
 dependendcies on CDO to your application code.

 The following diagram illustrates the major building blocks of a CDO application: <p align="center"><img src="application-architecture.png"></p>
