What is Domain Driven Design ? DDD is OO done well!
Domain Driven Design can be seen as a philosophy for developing applications based on specific domains and their logic where an ubiquitous language use is probably one of its most important features. If you’ve read Eric Evan’s book, then you’d probably agree that Eric hasn’t really introduced (or invented) anything new. On the other hand, you’ll surely noticed that his book (which is responsible for introducing DDD concepts to many!) presents several good design practices, techniques and principles which you can apply to solve problems associated with complex domains. So, in a way, you can see DDD as something that has grouped several known principles for domain modeling.
