domain-modeller

To map domain entities and boundaries before coding, identify core concepts, define entity lifecycles, and establish system ownership. This model-first approach clarifies data models and architectural boundaries across modules to prevent rewrites.

Yes, you can generate Mermaid diagrams for domain modeling. By providing domain context with key entities, relationships, and boundaries, the modeling process outputs visual Mermaid diagrams to guide implementation and clarify data architecture.

The best way to visualize entity-relationships for architecture planning is using a model-first approach that outputs Mermaid diagrams or Cypher-compatible graph structures. This clarifies relationships, cardinalities, and system boundaries for stakeholder communication.

Yes, domain modeling works with Cypher graph structures. The modeling process can output Cypher-compatible graph structures that map domain entities and relationships, visualising the model to guide implementation and data architecture design.

You need to define system boundaries and ownership for a feature when designing a system to clarify responsibilities across modules. Establishing boundaries early through domain modeling enables clearer communication with stakeholders and prevents architectural rewrites.

You should use a model-first approach for software design because it solves the problem of tacit domain knowledge and ambiguous entities. Capturing core concepts and lifecycles before coding clarifies data models and establishes clear architectural boundaries.
