			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>PointAbout is built on the Google App Engine platform. We love experimenting with new technologies and its free, so why not?</p>
<p>It has been a great learning experience for us. Just by usisng the platform we learned allot about <a title="BigTable abstract, the google datastore for google app engine" href="http://labs.google.com/papers/bigtable.html">database scalability</a>, although it took some arm twisting and mostly by force. After taking the time to think about why they did some thing the way they did we realized what most people do, Google had a great reason and we succumbed to the logic.</p>
<p>The inability to export and back up our data has been frustrating. I know that <a title="Forum for new back up system" href="http://groups.google.com/group/google-appengine/browse_thread/thread/1f0a26d8ec5fcf25/14e9c805f970bcd4?lnk=gst&amp;q=backup&amp;pli=1">Google is coming out with one &#8220;soon&#8221;</a> which I&#8217;m sure will be bad ass but since I only could find rumors of the date for release and mere claims that someone has shared some code I figured I would post the one I had to make for us. (I&#8217;m not one to wait for perfection, get &#8216;er done). I know its not perfect, heck its not even that great but I was able to <a href="http://code.google.com/p/pointabout/downloads/detail?name=datadump.py&amp;can=2&amp;q=#makechanges">get out data from google datastore and list it in sql</a>. Since PointAbout is a part of the &#8216;open initiative&#8217; we figured we might as well make it public. Let us know if you have improvements (which I&#8217;m sure the far smarter developers out there will).</p>
