Domain-Driven Design: Tackling Complexity in the Heart of Software

Why this matters here

Evans’s Domain-Driven Design argues for protecting core domain semantics from infrastructure-driven model drift—keeping business meaning from being overwritten by frameworks, vendors, and integration shortcuts. Coupling extends that boundary discipline under scale: as integrations multiply faster than organizational memory, external volatility leaks into core decision logic unless boundaries stay explicit. The book’s operational question is whether temporary mappings and convenience leaks remain harmless, or slowly make the system harder to change with understanding intact.
