Question

Are any alternatives to the Active Record in Rails?

Answer 1

Yes it is possible but not very easy.

In rails 3 the ORM layer will be pluggable and thus plugging in another ORM layer will be easier.

Answer 2

Datamapper is the biggest alternative ORM but there are others.

I steer clear because when you use these you really end up on your own out on the bleeding edge and as yet I haven't a need that justified the risk.
