Domain Driven Design

Blurb

Domain-driven design is an approach to software development for complex needs by connecting the implementation to an evolving model. The premise of domain-driven design is the following:
Placing the project's primary focus on the core domain and domain logic.
Basing complex designs on a model of the domain.
Initiating a creative collaboration between technical and domain experts to iteratively refine a conceptual model that addresses particular domain problems.
The term was coined by Eric Evans in his book of the same title.
