domain-driven-design

Domain-driven design structures software around business domains using bounded contexts and ubiquitous language. Use it to manage complex domains, decompose monoliths, and align code with business processes through domain expert collaboration.

Identify bounded contexts by delineating core business concepts, then outline aggregate roots to enforce invariants. Establish context maps to manage interactions between boundaries and use domain events for cross-boundary communication.

Yes, domain-driven design is explicitly used for monolith decomposition. By establishing explicit bounded contexts and context maps, teams can manage domain complexity and align software models with distinct business capabilities.

Aggregates enforce invariants by defining clear boundaries around aggregate roots. Domain events handle cross-boundary interactions, ensuring that separate bounded contexts communicate consistently without violating internal business rules.

Collaborating with domain experts evolves a shared ubiquitous language and distills the core domain. Consistent domain terminology reduces miscommunication and ensures the software models accurately reflect actual business concepts.

Domain-driven design requires close collaboration with domain experts and consistent terminology, making it less suitable for simple domains. Clear aggregate boundaries must be carefully maintained to enforce invariants without introducing unnecessary complexity.
