Hi, I would also recommend you to get the source code of Objectify, 1 of the open source datastore frameworks recommended by Google to work on top of its low-level ds api: very efficient and broad use of the ds capabilities.
I would also recommend the wiki pages of the project: perceived as very good by many people incl Ikai Lan from Google himself! ;-) regards didier On Feb 22, 5:14 pm, "Ikai Lan (Google)" <[email protected]> wrote: > I think one of the best ways to start learning about the datastore is to use > the low-level API: > > http://code.google.com/appengine/docs/java/javadoc/com/google/appengi... > > We changed our docs recently to show examples using this.
