title: How to define the name of my model class in my case?
body: <p>If I have a migration created table in database with name "<strong>number_updated</strong>", can I have the model name:</p>
  
  <pre><code>class NumberUpdated &lt; ActiveRecord::Base
    ...
  end
  </code></pre>
  
  <p>Why I ask this question is because by convention, rails use <strong>plural</strong> name for database table and singular name for model, for example, DB table name is "<strong>Cars</strong>" and model class name is "<strong>Car</strong>". But in my case, how the name should be?</p>
  
  <p>In rails, is every table name in database <strong>MUST end with 's'</strong> to indicate it is a plural???</p>
