This release contains all four versions of DDDSample.Net available in previous, 0.7 and a brand new one: Layered Model version. Layered Model demonstrates one of the patterns of strategic domain-driven design. Original cargo shipping model was partitioned into 4 business-driven layers: decision support, policy, operations and potential. Layering the model is not a technical decision (like layering in the architecture). It is a purely domain-related pattern and meaning of layers should be equally understood by both developers and business experts.
The big advantage of introducing layers to the model is grouping similar concepts (like location and voyage) and separating loosely-related ones. This, and other advantages of layers in the model can be seen best when comparing vanilla version with the new layered one.
