- Domain-Driven Design (DDD) focuses on understanding the business domain and fostering a shared language between developers and domain experts.
- Despite its potential, DDD remains niche due to its complexity, jargon, and academic presentation, which intimidates many developers.
- The core issue is that DDD has been overcomplicated with patterns and terminology, obscuring its simple, human-centered essence.
- Developers often mistake applying DDD patterns (like Aggregates, Bounded Contexts) as the goal, rather than using them as tools to model the domain.
- The real work of DDD involves deep engagement with domain experts, listening, and collaboratively developing a shared language.
- Event sourcing naturally aligns with DDD principles by focusing on business events, making domain modeling more intuitive and accessible.
- Pragmatic DDD advocates stripping away unnecessary complexity, emphasizing domain understanding, and using events to guide modeling.
- Key practices include talking to domain experts, using domain language in code, precise naming, and moving away from CRUD to domain-specific verbs.
