The Domain-Driven Design Paradigm

Design for the future, build for now.

DDD is modeling a business in the business's own language. The goal is not to avoid structure. It is to avoid structure you cannot back out of, and to defer structure you do not yet need.

What DDD Is

Ubiquitous language, bounded contexts, and a model built by talking to the people who do the work. The measure of a domain model is whether a person in the business would recognize their own job in it.

What DDD Is Not

Clean Architecture. Mandatory layering. A mapper between every tier. A count of design patterns applied before the first line of business logic is written.
