title: Is this a good idea to use Yii Framework with Doctrine 2 ORM?
body: <p>I love Yii Framework, it works fast, it's pretty cool and easy to develop with.
  But now I have a problem - I am going to develop Learning Managment System with difficult domain logic and it's not good for me to use Active Record from Yii for my models, it would be better to separate mapping and domain logic.</p>
  
  <p>So I decided to use Doctrine 2 ORM. It's pretty cool too, I liked it when previously I worked with it. But I think it's enough big for not so big Yii Framework.</p>
  
  <p>the main problems are</p>
  
  <p>1) I need some kind of ORM for separate domain logic and mapping. Are there any alternatives for Doctrine 2 ORM?</p>
  
  <p>2) I need good framework to work with this ORM. Is Yii well-suited to use it with Doctrine 2 ORM? Will it lose its benefits when I will use such big and not so fast ORM as Doctrine 2? Maybe it would be better to use Symfony 2 framework to work with Doctrine 2 ORM because they are natively in couple</p>
  
  <p>Thanks</p>
