title: Efficient way to pull data from second database?
body: <p>We have a primary database where all of our app resides.</p>
  
  <p>But there's a second database (updated from an external source), that I'd like to be able to connect to so I can pull data from it. I don't need to write anything...just read.</p>
  
  <p>It also only has one table that I'm pulling from.</p>
  
  <p>I really just need to do something like:</p>
  
  <pre><code>OtherDatabase.articles.where(id &gt; 1000)
  </code></pre>
  
  <p>And that's it.</p>
  
  <p>So how can I do this in Rails (running 3.2.13)?</p>
