The book discusses domain driven design (DDD) on several different levels:
- The importance to use the same domain model in all aspects of a project – in writing, in the spoken language and in the source code.
- The stereotyped building blocks used in modeling, design and implementation of domain centric software systems. Entity, Value Object, Repository, Service, Aggregate and a few more.
- How to use Strategic design and concepts such as Bounded Context to define current and future logical systems or enterprise wide architectures without having to unify the whole enterprise in a single domain model.
The book is the definitive starting point in learning and applying DDD, one of the really important design paradigms now and in the future. This book, together with the active community, both locally and on the Internet, has helped me in successfully designing and deliver complex software under complex technological and organizational circumstances. This is definitely one of the books I'm happy to come back to now and then and I think every professional software designer should have a copy. Before I first read it I was wondering why no one out in the “real” world used OO-design even remotely similar to what I learned and practiced in university. In his book Eric put this straight and he made me instantly feel “at home” with a true OO-design, carefully tuned to model the businesses, as the way to go about software design. Thanks Eric for sharing!
