Domain-Driven Design - DDD
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
By tightly binding software implementation to core business concepts (the domain model) and using a Ubiquitous Language to eliminate the communication gap between technical experts and business experts.
SCAFFOLDING EFFECT
Reduce cognitive load
Unify language and model. In any complex project, first unify the "glossary of terms." If not unified, the "user" that tech refers to and the "user" that operations refers to are not the same thing, and the system will inevitably collapse.
Anchor fast decisions
The core difficulty of complex software is domain understanding. DDD uses a "Ubiquitous Language" to unify the discourse of technology and business, and makes the model the single source of truth for code and communication, so that implementation aligns with business reality.
