title: Multiple database connection in cakephp 3
body: <p>I am trying to connect to multiple databases in <strong><code>cakephp 3</code></strong>. I have tried many times but all questions and answers are in <strong><code>cakephp 2</code></strong>. I found <a href="http://book.cakephp.org/3.0/en/orm/table-objects.html#configuring-connections">Configuring Connections</a> at <strong><code>cakephp 3</code> documentation.</strong> But I can't understand it.</p>
  
  <p>I have two databases :</p>
  
  <pre><code>1. tracking_system
       (Tables: trackers, events, etc..)
  2. tracking_system_2
       (Tables: todos, actions, etc..)
  </code></pre>
  
  <p>Working with database <strong>tracking_system</strong> is completely running.
  But I don't know, how to connect to multiple databases (in my case, with second database <strong>tracking_system2</strong>).</p>
  
  <p>Thanks in advance for help.</p>
