title: Yii2 Modules and configuration
body: <p>I'm not 100% sure that a module is the right way to go here. So thought i'd ask. My use case is that I have a fairly large application that is powered from an oracle DB. </p>
  
  <p>We also have another DB which isn't oracle and would be involved in a different type of work and a different user group, so I thought I should use a module - Is that right? If not what's the best way to achieve do this kind of set up?</p>
  
  <p>If so, is there a way to configure this second DB within my Module or should it be done within the main app/config/dp.php file?</p>
