Google I/O 2008 - Working with Google App Engine Models

Working with Google App Engine Models
Rafe Kaplan (Google)

Google App Engine Datastore Models have a lot in common with existing frameworks such as ActiveRecord and the Django database API. However, there are significant differences because of how the App Engine Datastore works. This talk will introduce the App Engine Model Framework and show how to use it to represent real-world information. Learn about the various types of information you can store using the Model and how to create relationships between entities. Beyond the basics, you can learn how to extend the model to store custom data types. In the course of this demonstration, we will build a model to represent a common and practical use case - User preferences.

"So I can say 'yes, I called you' [...] I can point to averages, and show her I talked 34 minutes on average [...] I think that's pretty good grandma-time"

Nice one :)

It is great to work with the Google Application Engine Models.

Can you suggest a link to a commented python file that contains some sample data and some commented examples like the examples you developed in this talk?

Regarding Dbase III, a really good thing about it was you could build and run the examples really easily. That is what I am looking for to help me understand the App Engine data model... a way to play with it.

Whevever I look at AppEngine, I come away with the impression that Google wants to completely own web application hosting... but that their ambition exceeds the capacity of even their extensive infrastructure. So they limit AppEngine devs to what amounts to Dbase III capabilities, and pitch it as the second coming of Christ.

IMO, while the Emperor may not be completely naked... he's is down to his skivvies.
