Modeling software around the business domain involves mapping bounded contexts, identifying aggregates, and establishing ubiquitous language with domain experts to reduce misalignment and enforce explicit boundaries.

The best way to coordinate across bounded contexts is using domain events, anti-corruption layers, and context mapping to prevent concept leakage and manage dependencies between distinct domain boundaries.

To enforce invariants when designing domain aggregates, apply tight aggregate boundaries and clear rules for distinguishing entities versus value objects to protect transactional consistency within your domain model.

You need an anti-corruption layer in domain-driven design when integrating with external systems or legacy subsystems to translate external models and prevent them from polluting your bounded context's ubiquitous language.

Yes, domain-driven design works for complex domain models by applying context mapping and bounded contexts to structure domain logic that accurately reflects real business capabilities and reduces architectural complexity.
