Domain-Driven Design (DDD) is an approach to software development that focuses on modeling the business domain of the software.

DDD aims to create software that is understandable by developers and domain experts and can be easily changed as the domain evolves.

DDD is based on the idea that the software should accurately reflect the real-world domain it is modeling. This means that the software should use the same terminology and concepts as the domain and be able to represent the complex interactions between different parts of the field.
