Overview
DDD is about mapping business requirements to a software model. It emphasizes the importance of understanding the 'domain' (the subject area the software is intended to apply to).
Key Concepts
- Ubiquitous Language: A language structured around the domain model and used by all team members.
- Bounded Context: A boundary within which a particular domain model is defined and applicable.
- Entities and Value Objects: Different types of domain objects.
- Aggregates: A cluster of domain objects that can be treated as a single unit.
Benefits
- Better alignment between software and business needs.
- Improved maintainability of complex systems.
