Domain Driven Design (DDD) is a set of principles and practices that help developers design and build software systems that are closely tied to the business domain. With DDD, developers strive to create a model that accurately reflects the real-world problem domain, rather than creating a model that is constrained by the limitations of a particular technology or framework. DDD also emphasizes the importance of building a system that is flexible and adaptable to change, achieved by breaking the system down into small, cohesive units. While challenging to implement, systems built using DDD are more aligned with the business domain, more flexible, and better suited to changing requirements. If working on a project that fits this description, consider giving DDD a try to unlock its full potential and create a system aligned with the needs of your users.
