A software design approach that focuses on modeling software around the business domain and its logic, emphasizing collaboration between technical and domain experts. It uses concepts like bounded contexts, entities, and aggregates to create a shared understanding of complex business problems.
Introduced by Eric Evans in his 2003 book 'Domain-Driven Design: Tackling Complexity in the Heart of Software'. The approach emerged from the recognition that the most complex part of software development is understanding and modeling the business domain, not the technical implementation.
DDD is like learning to speak the language of the business you're building software for - instead of translating everything into 'tech speak', you keep the business terms and concepts intact in your code! When an insurance company talks about 'policies' and 'claims', your code has Policy and Claim objects that behave exactly like the business experts describe them.
