Most times I've seem this pattern it was just an Anemic Domain Model, pretty much good old procedural style Tue, 08 Jul 2008 09:22:12 GMT zampano3000 http://tech.groups.yahoo.com/group/domaindrivendesign/message/7781 http://tech.groups.yahoo.com/group/domaindrivendesign/message/7781 Hi Folks! Hm, am I completely wrong or wasn't the first question in this thread if Services, as the third type of domain model object beside Entity and Value Tue, 08 Jul 2008 09:03:42 GMT Stuart Campbell http://tech.groups.yahoo.com/group/domaindrivendesign/message/7780 http://tech.groups.yahoo.com/group/domaindrivendesign/message/7780 I agree with Chris about the role of services, but, like Andrew, I have found that it does lead to domain model anemia. I'd also be interested to see an Tue, 08 Jul 2008 08:39:55 GMT andrewdeakins http://tech.groups.yahoo.com/group/domaindrivendesign/message/7779 http://tech.groups.yahoo.com/group/domaindrivendesign/message/7779 Hi Chris, I do have further questions regarding this. In your opinion, how would you avoid domain anemia in these cases? i'm not sure what behaviour an entity Tue, 08 Jul 2008 08:34:46 GMT Rickard Öberg http://tech.groups.yahoo.com/group/domaindrivendesign/message/7778 http://tech.groups.yahoo.com/group/domaindrivendesign/message/7778 Hi James! What you asked is an important question, and even though my answer will be Java-centric it might be helpful still. ... In the Qi4j-framework, if you Tue, 08 Jul 2008 08:15:55 GMT jjostexas http://tech.groups.yahoo.com/group/domaindrivendesign/message/7777 http://tech.groups.yahoo.com/group/domaindrivendesign/message/7777 I'm still new to domain driven design and have a design issue that I hope someone can help with. Within my domain I have an Item object that has a location.

No flames from me. In my opinion, you "get it".

Services play a critical role in DDD: they act as the boundary between the domain and applications.
