Tactical domain-driven design is a structured approach to organizing domain-centric code by defining aggregates, entities, value objects, domain events, and repositories to enforce transactional consistency within bounded contexts.

Design aggregates by mapping your bounded context to identify the aggregate root, its invariants, and related entities. This enforces transactional consistency by ensuring all changes within the aggregate boundary satisfy its defined business rules.

You need domain events for event-driven communication when coordinating actions across separate aggregates. They enable decoupled communication while maintaining the separation of concerns between domain logic and persistence boundaries.

Yes, tactical DDD identifies common domain model pitfalls and provides remedies. It detects anti-patterns by evaluating your aggregate design, entity lifecycles, and repository implementations against disciplined domain-driven design guidelines.

The best way to separate domain logic from persistence is by using repositories for persistence mapping and domain services for cross-aggregate logic. This ensures aggregates and value objects remain free of infrastructure concerns.

Defining value objects matters because they model attributes without identity, ensuring proper lifecycle management. They work alongside entities to encapsulate domain invariants and prevent common domain modeling pitfalls within your bounded context.
