The fundamentals of Domain-Driven Design (DDD) are easy enough to grasp and place into practice: develop a Ubiquitous Language within one or more Bounded Contexts to evolve objects that encapsulate the complexity of your application. Design gets significantly more challenging when you encounter a multiple domains or multiple teams. In short order you?ll be confronted with hard questions: How do I integrate multiple models? How do I share elements between models? How do I integrate modeling efforts across multiple teams in a large enterprise? This session will tackle the problems associated with introducing DDD in large, non-trivial systems and rolling out the practice in the enterprise. We?ll review a number scenarios where different patterns can be leveraged to maintain model integrity and elegance.
