Again, I'm finding this much later than I should have, but Frans Bouma has an article talking about different methods to develop your software. Not Agile versus waterfall, but actual architecture, like managers versus a domain model.

It's a good discussion, and it's from the perspective of how O/R mappers fit each model, but it also provides a good description of each approach. He based this on a discussion of O/R Mappers over at the ASP.NET Forums. The thread is interesting - it gets heated at points, and even turns into a discussion of mappers versus code generators! It's amazing how heated some of these types of discussions can get.
