title: Persistence in Google App Engine (Java) - accessing data outside the application
body: <p>I'm on the process of designing a web application based on Google App Engine (Java) platform. I'm basically from <em>relational database world</em> and I'm trying to understand how to use the persistence that GAE provides. </p>
  
  <p>So my questions is, in RDBMS, I can easily access my data without going through my application. i.e, I can use an SQL client to connect to my data and manipulate it. Is the same thing possible with GAE?</p>
