Thus, one will be able to use any ORM or object store that supports the ActiveModel API. Now, in regards to DataMapper and GAE, DataMapper is an ORM similar to ActiveRecord but it interfaces with a non-relational database called BigTable. It's a key value store and indexes are automatically created for you. Furthermore, the notion of joins are not supported but optimistic transactions are supported within the BigTable. Last but not least, GAE automatically scales your application for you and the 5 million or so page views are free per month. I would recommend playing with the various technologies and learning what works best for your project.
