About Domain-driven design¶

Quote

Domain-driven design (DDD) is a major software design approach, focusing on modeling software to match a domain according to input from that domain's experts.

Under domain-driven design, the structure and language of software code (class names, class methods, class variables) should match the business domain. For example, if software processes loan applications, it might have classes like loan application, customer, and methods such as accept offer and withdraw.

Domain-driven design is predicated on the following goals:

• 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.
