It's probably not the easiest thing to wrap your head around, but I think it's a very interesting idea, and I think being able to seperate behaviour from state into first-class "units" would make it much easier to reason about the code. It's hard <strong>not</strong> to try and think of DCI in terms of familiar programming languages such as Java, but that will probably trip you up. I would recommend taking a look at Ruby (mixins in particular), since it's more easily done there. A former collegue of mine, Steen Lehmann, has done a sample implementation of DCI in Ruby. James Coplien has included some of the code in this presentation from Öredev, which I recommend you take a look at: <a href="http://folk.uio.no/trygver/2009/20091106OeredevJim.pdf" rel="nofollow">http://folk.uio.no/trygver/2009/20091106OeredevJim.pdf</a> Hi Tailor, thanks for you comment.

Still not grasping it. took me nearly 10 years to master OOP so I suppose there's no hurry. Taylor Erik,

Nice DCI summary. Still not grasping it. took me nearly 10 years to master OOP so I suppose there’s no hurry.
