Greg Young at Devnology

September 17, 2009

Yesterday I attended a Distributed Domain Driven Design presentation given by Greg Young and organized by devnology at Xebia office. In the past I have been playing with DDD concepts but a lot of questions remained unanswered, even after asking them to Eric Evans when he was at the Xebia office a few years ago.

The information provided by Greg made a lot of sense and it was nice to see that there is a better way for writing domain driven applications instead of the current often awkward approach. Creating different models for different needs and storing the event chain instead of storing the new state of an object really made sense. So it is certainly something I want to experiment with in the future. The well known “Patterns of Enterprise Application Architecture” written by Martin Fowler and “Domain-Driven Design: Tackling Complexity in the Heart of Software” written by Eric Evans, made the first steps in the enterprise domain driven design possible, but I think that Greg could lead us to the next step.

Apart from the technical content (very very important to me) it was also nice to see an enthusiastic and professional speaker. I would certainly place him in the same league as Fowler and Evens and I think that we are going to hear more about Greg in the future (a book perhaps?).
