title: What exactly counts as using AJAX
body: <p>From my understanding, AJAX requires the use of the XMLHttpRequest object. What I am confused on is the source of where the XMLHttpRequest object is connected to? In the school projects, I have connected it to XML and mySQL and was told that I am doing AJAX. What if I connect the XMLHttpRequest object to a PHP script which contains an array of data? Would that count as AJAX? </p>
  
  <p>The reason why I ask is because I was thinking of adding AJAX to my resume, but since this area seems so broad and I have had limited experience with it, I want to make sure I have a clear understanding of this technology.</p>
