I have just finished watching the following videos in an attempt to understand JDO and BigTable for the google datastore:
http://www.youtube.com/watch?v=2jW2iSKDipY http://www.youtube.com/watch?v=Yl_J-UYE94w http://www.youtube.com/watch?v=pzctc48c0BM http://www.youtube.com/watch?v=tx5gdoNpcZM Now I wonder, take the example where we have an entity of kind Grandparent having an entity of kind Parent having an entity of kind Child as in one of the videos. The key for one of the the Child entities could be: Grandparent:Jane/Parent:Jack/Child:Joe 1. How do I code the class for this instance in JDO (presumably there will be three classes) but I would like to see an implementation where we can see the key values set as part of the key explicitly. Any ideas? 2. I also wonder, what is the difference between using JDOQL to access my data and iterating through the various instances using iterators programmatically?
