Java Data Objects JDO with App engine

To bind data to Java Objects and store it in Google App Engine the following API can be used and recommended:


* Objectify is a very simple and convenient interface to the App Engine Datastore that helps you avoid some of the complexities presented by JDO/JPA and the low-level Datastore.
* Twig is a configurable object persistence interface that improves support for inheritance, polymorphism, and generic types. Like Objectify, Twig also helps you avoid complexities posed by JDO and the low-level Datastore.
* Slim3 is a full-stack model-view-controller framework that you can use for a wide variety of App Engine functions, including (but not limited to) the Datastore.
