title: ON DELETE CASCADE
body: <pre><code>ALTER TABLE `phppos_items_taxes`
  ADD CONSTRAINT `phppos_items_taxes_ibfk_1` 
  FOREIGN KEY (`item_id`) 
  REFERENCES `phppos_items` (`item_id`) 
  ON DELETE CASCADE;
  </code></pre>
  
  <p>Does this mean when <code>phppos_items.id</code> is deleted, it will be delete entries on <code>phppos_items_taxes</code>?</p>
  
  <p>I am just have a hard time interpreting it.</p>
