A software's domain governs its context, the setting in which a word or statement appears that determines its meaning. Of primary importance is domain, the subject area to which the user applies a program is the domain of the software.

2.2 Command Query Responsibility Segregationĭomain-driven design articulates a number of high-level concepts and practices.

2.1 Model-driven engineering and architecture.

The term was coined by Eric Evans in his book of the same title published in 2003. While domain-driven design provides benefits such as maintainability, Microsoft recommends it only for complex domains where the model provides clear benefits in formulating a common understanding of the domain.

initiating a creative collaboration between technical and domain experts to iteratively refine a conceptual model that addresses particular domain problems.Ĭriticisms of domain-driven design argue that developers must typically implement a great deal of isolation and encapsulation to maintain the model as a pure and helpful construct.

basing complex designs on a model of the domain.

placing the project's primary focus on the core domain and domain logic.

ĭomain-driven design is predicated on the following goals:

For example, if a software processes loan applications, it might have classes like LoanApplication and Customer, and methods such as AcceptOffer and Withdraw.ĭDD connects the implementation to an evolving model.

In terms of object-oriented programming it means that the structure and language of software code (class names, class methods, class variables) should match the business domain. Domain-driven design ( DDD) is a software design approach focusing on modelling software to match a domain according to input from that domain's experts.
