Eric I enjoyed reading the draft of your book. I might disagree with a few points, but overall I think it is a valuable contribution to the field. I wonder if...

Richard, I read your book and found it fit well with work I was doing last fall (got the book at OOPSLA). We took a slightly different approach, but the goal...
I'm not working on a book or a Ph.D., so I'm not sure I can authoritatively join this thread, but I read both these books recently (concurrently at times) and...
I am aware of the Naked Objects framework, but don't know a lot about it. It is definitely an attempt to drive design from the domain. When I read about it, I...
... of ... Please do participate. I don't have a Ph.D. either. I think you are right: Naked Objects is an attempt at a concrete application of domain-driven...
I think the key to placing use cases within domain-driven design is the "ubiquitous language". The model is our developing understanding of the domain we're...
... This is a common and very understandable reaction to the Naked Objects concept. To begin with it seems unlikely that all user actions would map onto...

Hi, I am a newbie to the world of domaindriven. I have come across a vendor statement to the effect that J2EE does not offer much support to the domain-centric...
I'm afraid that is a complicated question. I suppose the short answer is yes, domain-driven designs are done in J2EE, although it is a complicated framework,...
It is interesting. I like the emphasis on the model, and the attitude that you refuse to compensate for a weak model with a complicated application layer. That...
Hi, Panayotis. Thank you for posting these interesting questions. In future, I'd like to ask people to avoid MS Word documents, because they cause problems for...
Eric, I recently downloaded your book and have been reading through it as time permits. I am a newbie when it comes to OO*. From the books and articles that I...
Hi, Hemant. Thanks for the comments. I agree and disagree. True, refactoring domain models can be very expensive. But costs don't necessarily increase with...
Hi Hemant, ... Your statement is of great interest to me and brings to my mind two questions. My first question asks: do you believe that somewhere in the ...
Dan/Eric, Let us consider a Sale event in an enterprise. Logistics will see a Sale event as an invoice; Accounts will see the same event as a debit entry for...
Hemant, thanks for providing a concrete example. That will help keep us on track. Let's talk about the question of how that modeler would reconcile those views...
Thanks for the link. I looked through it. It is a slide presentation, and so it is risky to interpret without the having heard the talk that goes with it. With...
Dear Eric, (quoting the 1st letter) <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> I would be more than grateful if you could...
Eric, I am fully for domain driven design! ...domain-driven design should work in any process that provides adequate means of learning about the domain and has...
Well, I do advocate Agile/XP methodologies, but I don't want to entangle the issues too much, and I'm open minded about different approaches. I'm not sure what...
Ok, I still don't know what this is really for, but I'll make some general observations, and then maybe we can narrow it down if you can explain what the...
As I said in my first mail I am an object newbie. I come from a data oriented backgroud where we try to capture the domain in a conceptual model and then...
In my opinion, MeasurementUnitDomain and MeasuremenUnit should be value objects, not entities. They are mathematical objects, not real world objects, and I...
Hi Hemant, ... Even though stakeholders may see the Sale event differently, essential facts are present that each user (stakeholder in the sale) holds in...
Hello everyone, I've been working my way through the DDD book cover to cover and I'm currently finishing up Part III. The book has been extremely useful so...
