title: EntityBean, SessionBean, databean and accessbean
body: <p>I have been trying to learn about the Java beans in WebSphere Commerce but I got really confused. Please help me out. I need to know:</p>
  
  <blockquote>
    <p>What is the difference between <code>EntityBean</code>, <code>SessionBean</code>,
    <code>DataBean</code> and <code>AccessBean</code> and how do they compare?</p>
  </blockquote>
  
  <p><br> Though I found the difference between Session and Entity, and between Access and Data, I fail to understand how they are all related to each other.</p>
  
  <p>All the help would highly be appreciated.</p>
