“Interactions with domain experts play a key role in implementing software. You have to make sure that you understand the problem you’re solving. You cannot provide a software solution without understanding the problem first."
Vladik Khononov is the author of “Learning Domain-Driven Design”. In this episode, we discussed in-depth about Domain-Driven Design (DDD) and Vlad started by sharing why understanding business domain is crucial in software engineering and how DDD can help build the shared understanding between domain experts and software engineers. Vlad then explained the two important designs in DDD, i.e. the strategic and tactical designs, and how they relate to each other. For each design, Vlad touched on some important patterns, such as bounded context, context map, subdomain, aggregate, entity, and value object. Towards the end, Vlad gave great tips on applying DDD to brownfield projects and how those projects can benefit the most from some of the DDD practices.
