domain-driven-design

Structure software with bounded contexts and aggregates by identifying root entities to maintain invariants and establishing context maps to manage integration boundaries. This organizes code into clear modules with consistent domain language.

You need domain-driven design when refactoring complex software where consistent domain language and boundaries matter. It aligns software models with business concepts, improving clarity, modularity, and maintainability during architecture planning or code reviews.

Implement value objects to model essential domain concepts and enforce invariants within boundaries. Coordinate behavior using domain services while keeping the domain pure and ensuring repositories expose root-level access only.

The best way to define a domain model is by identifying bounded contexts and aggregates first, then implementing domain objects with value objects and domain services. This ensures aggregates enforce invariants and repositories expose root-level access.

Yes, domain-driven design works for code reviews of complex domains by evaluating whether aggregates enforce invariants, domain services coordinate behavior, and repositories expose root-level access while keeping the domain pure.

Use bounded contexts and context maps to manage integration because they establish clear boundaries that align software models with business concepts, improving clarity, modularity, and maintainability across complex domain integrations.
