Domain-driven design (DDD) is a software development approach that centers around modeling a domain into objects based on how an expert in that domain would naturally describe it. The presentation introduces key DDD concepts like ubiquitous language, context, domain models using entities, value objects, repositories, services, and commands. It notes pros of DDD like separated business rules, readable code, and ease of maintenance, as well as cons like code overhead and a steep learning curve. The presentation concludes by thanking the audience.
