Hi Mr Fixxit,
Sorry for the late reply!
Take a look at this blog post on the differences between the domain and application services http://stochastyk.blogspot.com/2008/...en-design.html
. I like to think of my application services as being the API into the code, a client interacts with the API (application services) and behind the scences and within the domain model a domain service may use multiple entities and value objects in collaboration to fulfill a business request.
I hope that answers your question, if not please respond and we can talk about the differences further.
