domain-driven-design

Domain-driven design aligns software models with business concepts by applying strategic design to organize complex domains and tactical design to enforce invariants. This modeling approach reduces ambiguity and rework by reflecting the domain directly in code and language.

Strategic design in DDD organizes complex domains using bounded contexts, context maps, and ubiquitous language. Tactical design implements invariants and clear boundaries using entities, value objects, aggregates, and repositories to enforce domain rules.

Event storming captures business processes by modeling domain events that enable eventual consistency. This DDD technique helps teams discover bounded contexts and design multi-language implementations across Hexagonal, CQRS, and Event Sourcing architectures.

Domain-driven design supports language-aware implementations and code-review guidance across Python and TypeScript. It provides domain events and repository ports to enforce domain boundaries consistently in these programming languages.

Bounded contexts and domain events are needed when developing complex, evolving domains that require eventual consistency. They help align software with business domains, enforce boundaries, and enable architectures like CQRS and Event Sourcing.

Domain-driven design works with Hexagonal, CQRS, and Event Sourcing architectures by enforcing domain boundaries and providing repository ports. It offers comprehensive guidance for events, design, and code reviews across these architectural patterns.
