Summary

This chapter explores Domain-Driven Design (DDD), a software development methodology that aims to align software systems with complex business domains. DDD focuses on creating models that accurately reflect the domain by fostering collaboration between technical teams and domain experts. The chapter emphasizes the importance of understanding and structuring domain elements to build systems that are adaptable, maintainable, and aligned with business goals. This approach is particularly beneficial for applications like healthcare management systems, which involve intricate relationships, workflows, and rules.The chapter begins by introducing the foundational concepts of DDD, including entities, which are objects with unique identities and lifecycles. Entities, such as Patient in a healthcare system, represent distinct objects whose attributes may change over time while their identity remains constant. DDD also relies heavily on models, which serve as abstractions to solve domain...
