Domain-driven design (DDD) organizes software domains by aligning structure with business concepts. It reduces architectural complexity by enforcing clear boundaries through strategic patterns like bounded contexts and tactical patterns like aggregates and domain events.

Separate a domain model by deploying a small prototype and dividing it into bounded contexts and aggregates. Apply DDD tactical patterns like entities, value objects, and domain events to enforce clear boundaries and reduce architectural complexity.

Context mapping is needed when multiple teams work on interdependent bounded contexts. DDD provides context mapping guidance to coordinate multi-team architectures, establish anti-corruption layers, and evolve complex enterprise domains while maintaining clear boundaries.

Entities possess unique identity, value objects are defined by attributes, and domain services handle stateless operations. These DDD tactical patterns organize domain logic within aggregates and bounded contexts to reduce architectural complexity in enterprise systems.

DDD is specifically designed for complex enterprise systems with multiple bounded contexts. It enforces clear boundaries and provides strategic and tactical patterns to manage architectural complexity, making it ideal for multi-team domain modeling.

Avoid DDD aggregates and domain events when modeling simple domains lacking complex business rules. DDD targets complex enterprise systems with multiple bounded contexts; applying it to small domains introduces unnecessary architectural overhead and cognitive load.
