What is DDD?

DDD stands for Domain-Driven Design. It is a software development approach that centers the development process around the domain, or the specific area of expertise the software is intended to serve. DDD focuses on creating a shared understanding of the domain between developers and domain experts (e.g., business analysts, subject matter experts). It emphasizes modeling the domain, using a ubiquitous language to represent concepts and rules, and structuring the software to reflect the domain model. This results in software that is easier to understand, maintain, and evolve as the domain changes. Key concepts include entities, value objects, aggregates, repositories, and domain services. DDD is commonly used in complex business applications where the domain logic is intricate.
