You can use Data Mapper and Sequel, albeit with small tweaks. Rails 3.0 will bring ORM agnosticism, so you're free to choose. Now, Active Record is still much easier specifically for green-field projects. It was not made for legacy integration. It was never a goal to reach more than 80% of the needs - remember Paretto ;-) And although Active Record is the de facto Rails-way, it is not alone anymore.

It uses a different pattern from ActiveRecord, and using it you would have something like: <pre><code> class Organization include DataMapper::Resource property :id, Serial, :key => true property :name, String, :nullable => false property :url, String belongs_to :org_type end </code></pre> It's just beautiful, IMHO :) Rails integration isn't perfect, but I believe it will be seamless with Rails 3.0. It's worth a look. Cheers Besides annotated models you can use DataMapper (http://datamapper.org/), created to be Merb’s ORM, but can be used with Rails too.

		This can be done automatically for you with annotate models. http://pragdave.pragprog.com/pragdave/2006/02/annotate_models.html
