In domain-driven design, the domain layer is one of the common layers in an object-oriented multilayered architecture.ĭomain-driven design recognizes multiple kinds of models.įor example, an entity is an object defined not by its attributes, but its identity. These aspects of domain-driven design aim to foster ubiquitous language, meaning that the domain model should form a common language shared by domain experts for describing system requirements, business users, sponsors and developers. From this, developers build a domain model: a system of abstractions that describes selected aspects of a domain and can be used to solve problems related to that domain.

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.

One concept is 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.
