Easy ORM-ness for GAE

Objectify-Appengine is one of an emerging class of tools that extend the convenience of NoSQL, in this case by providing a Hibernate-style mapping layer between your application and the GAE datastore.

In this month’s Java development 2.0 series dubbed “Twitter mining with Objectify-Appengine, Part 1” you’ll learn about Objectify’s handy, JPA-friendly (but not dependent) API; plus, this article walks you through the steps of mapping Twitter retweets into Bigtable, in preparation for deploying it in Google App Engine.

In addition to this article, there are a few other resources for GAE and NoSQL including:

• “Schemaless data modeling with Bigtable and Groovy’s Gaelyk“
• “Gaelyk for Google App Engine“
• “Hello Google App Engine“

Part 2 of “Twitter mining with Objectify-Appengine” will take the newly minted domain objects and plug them into a web application running on GAE; more over, the article will sprinkle in a bit of Ajax and JSON.
