 <p>
 Turbine follows the MVC desing pattern.
 </p>
 <p>
 <ul>
 <li>  Model      - the underlying data sources (via peers or beans)</li>
 <li>  View       - one of the templating engines</li>
 <li>  Controller - Turbine servlet plus your action+screen classes</li>
 </ul>
 </p>

 <p>
 Since the view and the controller are tightly coupled in Turbine,
 it is stated to follow the Model2 design pattern, with a + 1
 addition due to way actions are used (hence Model 2 + 1).
 </p>

 <p>
 Turbine does not directly support the Hierachical MVC pattern, but
 it cout be used this way by defining multiple module and template
 paths (would impact performance). Note that in the HMVC each MVC
 instance is self-contained and separable from the rest.
 </p>

 <p>
 Note that many components within a MVC system follow themselves
 the MVC pattern, therefore most MVC systems are also HMVC systems
 (this also applies to Turbine as a whole, but your application with
 Turbine is normally not HMVC).
 </p>

 <p>
 Also note that you could use Turbine in a non MVC manner, but
 normally it leads you to use it as MVC (which JSP does not).
 </p>

 <p>
 I hope this clarifies your question,
 Christoph

 That is a GREAT explanation and I'm going to use that for now on...except it
 isn't entirely true. :-)
 </p>

 <p>
 The +1 was a joke on my part to see what people would do with it. I figured
 that people were believing this Model 2 hype with JSP and such and I wanted
 to improve on it. I love playing with marketing games. I read that Model 2
 paper and then figured that Turbine was better than what they declared as
 Model 2.
 </p>

 <p>
 Calling it Model 3 would have been like saying that Turbine was just a third
 generation of Model 2. So, instead I figured that making it +1 just made it
 appear to be an improved Model 2 model since that is what Turbine really is.

 </p>

 <p>
 Oh yea...one more reason for the +1...
 </p>

 <p>
 It is the Apache <a href="http://jakarta.apache.org/guidelines/decisions.html">voting style</a>. :-)
 </p>

 <p>
 Turbine is Model 2 .......... +1 ! :-)
