domain-driven-design

Domain-driven design modeling codifies business concepts into a cohesive domain model by identifying aggregates, entities, and value objects. You provide a domain description, and it translates business rules into a structured, testable design with formalized invariants and repository boundaries.

Defining bounded contexts establishes explicit boundaries to prevent term ambiguity and enable context-specific vocabularies. By mapping these boundaries, you isolate domain models, ensuring that terms have precise meanings within their specific business contexts.

Visualizing domain events and aggregate relationships generates Mermaid and Graphviz-style diagrams from your domain model. This clarifies complex domain structures and communicates workflows effectively across your team.

Refactoring an existing domain model detects inconsistencies, improves ubiquitous language, and aligns models with business rules. It evaluates your current structure against domain-driven design principles to identify entities, aggregates, and domain events for a more robust, evolvable design.

Domain-driven design should not be used for simple domains lacking complex business rules or rich behavior. It is intended for complex domains where translating business concepts into a cohesive model and establishing ubiquitous language significantly reduces miscommunication.

You do not need an existing domain model to start applying DDD principles. You can provide a concise domain description, and the approach will outline a domain model complete with aggregate roots, internal entities, and domain events.
