MacRuby - ActiveRecord for storage?

Is it possible to use ActiveRecord for storage and query in a MacRuby Cocoa application开发者_开发知识库?

If it is, are there any resources that shows how?

Are there any reason why ActiveRecord should not be used?

Yes, it is. It's a Ruby library, you can use it without any problem.

However, ActiveRecord is a quite huge library. You might not need all its features. If you simply need to connect to a database and perform operations, I strongly encourage you to give Sequel gem a try.
