title: What is the difference in Extension & Add Ons in Hybris
body: <p>I suppose   Default  <code>Extension</code> can  Encapsulate  Business  Logic, Type  Definitions,  Configurations  &amp;  Add  Ons.</p>
  
  <p>I  Know that <code>Add On</code>  is Also a Type  Of  <code>Extensions</code>  that Extend Normal  Extensions.</p>
  
  <p>I further know that Add  Ons  Extend  Functionality  without  Touching CODE  Base.</p>
  
  <p>Any Inputs from Hybris Experts Highly Appreciated.</p>
