Domain-Driven Design (DDD)

Domain-Driven Design (DDD) is a software development philosophy that structures a project around a specific business area, or "domain." It emphasizes building a shared, common language between developers and domain experts to create software that accurately reflects the real-world business logic and rules.

Example: A financial services company is building a new trading platform. Using DDD, the development team and financial experts would collaborate closely to create a shared vocabulary and model for key concepts like "trade," "order," and "portfolio." The software's design and code would be built directly from this shared understanding, ensuring that the system's logic and behavior accurately represent the complexities and rules of financial trading.
