Ruby developers are living in the world of Active Record. No matter what ORM you're using, it's an implementation of the Active Record pattern. There's been a recent discussion in our community about separating business logic from the persistence concerns. People are experimenting with different approaches but they still use an ActiveRecord ORM under the hood. In this presentation I will give you an introduction to the development of DataMapper 2 - the first true implementation of the Data Mapper pattern in Ruby language. I will talk a little bit about ORM patterns and show you core parts of DM2 that already exist and the ones we're going to build soon.
