I my CQRS example client and account are two different Aggregate Roots, and between two AR's Fri, 20 Nov 2009 23:40:49 GMT Mike Chaliy http://tech.groups.yahoo.com/group/domaindrivendesign/message/16393 http://tech.groups.yahoo.com/group/domaindrivendesign/message/16393 Thank you for your opinion. I get it. So for you semantics of this methods are equivalent? They both means passing reference to the product? By the way, in Fri, 20 Nov 2009 23:25:32 GMT Mark Nijhof http://tech.groups.yahoo.com/group/domaindrivendesign/message/16392 http://tech.groups.yahoo.com/group/domaindrivendesign/message/16392 Hi Mike, Ok to literally answer your question :) if you already hold a reference to the entity then pass that in, if all you have is the Id and you are not Fri, 20 Nov 2009 21:42:36 GMT Mike Chaliy http://tech.groups.yahoo.com/group/domaindrivendesign/message/16391 http://tech.groups.yahoo.com/group/domaindrivendesign/message/16391 Mark, could you elaborate on this? Really I cannot understand your statement. My problem is just passing reference of the entity to the service. Nothing more.

And I have domain service: class FooService { public void DoSomething(Product prod); } When calling DoSomething I can pass object so I Fri, 20 Nov 2009 18:59:35 GMT Justin Daubenmire http://tech.groups.yahoo.com/group/domaindrivendesign/message/16388 http://tech.groups.yahoo.com/group/domaindrivendesign/message/16388 ...

Also, what do you use to map returned data from a stored procedure to your domain entities and value objects? thanks.

I've automated it to the point where we don't Fri, 20 Nov 2009 17:48:55 GMT Justin Daubenmire http://tech.groups.yahoo.com/group/domaindrivendesign/message/16383 http://tech.groups.yahoo.com/group/domaindrivendesign/message/16383 Guys, Sorry for the slightly off topic post but I wanted to ask for some input from everyone. I am working on a project that uses 100% stored procedures.

They are about representation, function, behavior, capability, Fri, 20 Nov 2009 15:54:02 GMT Nuno Lopes http://tech.groups.yahoo.com/group/domaindrivendesign/message/16381 http://tech.groups.yahoo.com/group/domaindrivendesign/message/16381 ... Hi Jer, The use of lookup keys is an implementation detail (or Indexes) of for instance the Repository. Is like your event replay to reconstruct the AR, it Fri, 20 Nov 2009 11:30:36 GMT J??r??mie http://tech.groups.yahoo.com/group/domaindrivendesign/message/16380 http://tech.groups.yahoo.com/group/domaindrivendesign/message/16380 Yes, but this kind of uniqueness is usually bound to lookup key uniqueness. Those lookup keys are never used in the domain itself. They are used to find
