Domain-Driven Design (DDD) is an approach to software development that focuses on understanding and dealing with complex business needs. We will explore the strengths of DDD, including its approach to structuring software around an abstract model of a business problem and creating a ‘ubiquitous language’ for communication among developers and domain experts. We’ll look at the strategic and tactical aspects of DDD and show that the central benefit of this approach is improved collaboration, better understanding of business processes, and ultimately, better and more flexible software. by Rob Allen
