Silicon Valley Web Developer Java Users Group
16 September 2009, Googleplex

Socialwok is a social networking site, FaceBook for people who are currently work together. People from SocialWok told us about how they made their product, the largest application running on Google’s App Engine with Java.

SocialWok was able to develop the whole app in Java, the back end running on App Engine and the front end Java code they compiled into JavaScript using Google Web Toolkit. They said it was a big advantage being able to use just one language for an entire Web application. Starting development in May, their four engineers had an impressive array of features running now, only 4 months later.

Then Max Ross talked about “The Softer Side of Schemas”
He was referring to Google’s Datastore, which is NOT relational.
Google has made up their own database model, where the constraints to the data are enforced purely in the application layer. Max said that the data model is hierarchical, but I’m sure it is more then that. I will have to study it further!

To study:
Google Data API’s (GDATA)
JDO and JPA

To test:
Editing a Google doc while offline. This should show me how Google Gears works.
