The original title is "When to skip deep domain modeling: a practical guide"
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
