I am retrieving my entities and aggregates on each service call from Wed, 15 May 2013 02:50:50 GMT Rickard Öberg http://groups.yahoo.com/group/domaindrivendesign/message/24069 http://groups.yahoo.com/group/domaindrivendesign/message/24069 ... This depends a lot on whether your app is clustered or not, i.e. if it is the same server that gets write requests. You can always add caching of the Tue, 14 May 2013 19:50:34 GMT j.vieten http://groups.yahoo.com/group/domaindrivendesign/message/24068 http://groups.yahoo.com/group/domaindrivendesign/message/24068 yes your explanation does get me started. I do plan to use a web REST Service. What is special about my use-case is that my entities need to provide many Tue, 14 May 2013 19:07:02 GMT Jörgen Andersson http://groups.yahoo.com/group/domaindrivendesign/message/24067 http://groups.yahoo.com/group/domaindrivendesign/message/24067 Hi, From a DDD-point-of-view both approaches will work. In both cases you build a domain model to contain the business state and logic. The difference is in Tue, 14 May 2013 16:05:53 GMT j.vieten http://groups.yahoo.com/group/domaindrivendesign/message/24066 http://groups.yahoo.com/group/domaindrivendesign/message/24066 Hello, I am very new to DDD... Many examples I have seen so far more or less reconstruct their Domain Object Model (DOM) on every service call.

Something like a person's name may never change, or may change once in a long while. But given that Mon, 13 May 2013 17:09:33 GMT Mirko Sertic http://groups.yahoo.com/group/domaindrivendesign/message/24064 http://groups.yahoo.com/group/domaindrivendesign/message/24064 Hi there In fact it is Enterprise Architect 10 with "Hand drawn" diagram types:-) Regards Mirko ...

In this example i *tried* to explain that messages are not forwarded to the target messaging system, because this system might be unavailable for Mon, 13 May 2013 16:56:00 GMT Mirko Sertic http://groups.yahoo.com/group/domaindrivendesign/message/24062 http://groups.yahoo.com/group/domaindrivendesign/message/24062 Sorry, i meant Enterprise Architect 10 for UML, it was too late.... ...

I've been to munich the last weekend, the bavarian people know how to party:-) I am using 10 for UML stuff.

I just don't use Id classes to do it.. If you start lazy loading from Id classes I see a big mess Mon, 13 May 2013 10:25:53 GMT Wim van Gool http://groups.yahoo.com/group/domaindrivendesign/message/24059 http://groups.yahoo.com/group/domaindrivendesign/message/24059 @Greg: I agree that encapsulating identifiers with custom types might be a bit too puristic in the sense that you will hardly even change them - and not only Mon, 13 May 2013 02:04:37 GMT Greg Young http://groups.yahoo.com/group/domaindrivendesign/message/24058 http://groups.yahoo.com/group/domaindrivendesign/message/24058 Soft links do not require special Id classes. I have found guids to work quite well (Uris work well too) I run a risk that my domain would see a large change Sun, 12 May 2013 18:07:44 GMT Michael Schuerig http://groups.yahoo.com/group/domaindrivendesign/message/24057 http://groups.yahoo.com/group/domaindrivendesign/message/24057 ... Well, I've written my fair share of code that passes around IDs and I'm not particularly proud of it. My point, however, is slightly different.

I challenge anyone to come up with a valid use case for this nonsense that has been spread around. ... -- Le doute n'est pas une condition
