Original: LLD Domain Modeling: When NOT to Use Domain Modeling (Very Important Reality Check)

Short summary

A guide on when deep domain modeling is warranted versus when it adds unnecessary complexity. The core principle: match design complexity to domain complexity — use aggregates, state machines, and bounded contexts only when race conditions, complex lifecycles, or cross-domain workflows demand them. Simple CRUD apps, admin panels, and static content systems should stay simple. The best design fits the problem, not the pattern catalog.

  • Deep domain modeling should be driven by real business complexity, not applied universally
  • Use aggregates, state machines, and bounded contexts only when race conditions, lifecycles, or cross-domain workflows exist
  • Simple CRUD and admin panels should avoid unnecessary abstractions — start simple, add structure when complexity demands it
