title: Rules Object Model: Declarative vs POJO
body: <p>I have read that is wise to keep the Rules Object Model separate from the Business Layer Object Model. drools-guvnor supports two models: declarative and POJO. Which is better to use in a large enterprise app?</p>
  
  <p>The envisaged architecture consists of Presentation+Business Layer on one app server and guvnor with a wrapper web service on another, where the Rules WS exposes SOAP web API for the business logic to validate the rules.</p>
