title: CBO coupling between object
body: <p>I don't understand what "CBO-Coupling between object classes" really means. The definition I found is so short that I think I'm missing something, so it would be great if you help me with an example.</p>
  
  <p>Here is the definition I found:
  "The coupling between object classes is a count of the number of other classes to which it is coupled."</p>
  
  <p>Thanks in advance.</p>
