Re: Re: Created DDD Exampe - Feedback?

Hi there

No problem at all. I am glad to share my thoughts with the community.

This is an interesting point, and yes, it is a business rule. The idea 
behing this example is there there are independent applications for each 
bounded context, because every bounded context serves a different user 
group. And the Customer Management users do not think in terms of 
Projects, they think about Customers. And if we want to apply a business 
rule check across multiple bounded contexts/applications, we need some 
kind of sync/async context integration. In this case, we cannot move the 
Project to the Customer Management BC. If there would only be one big 
application with multiple modules(one per BC), the business rule 
enforcement could also easily be coordinated by an Application 
Service(which is also the case in my example).

Regards
Mirko
