Is a software development methodology that emphasizes aligning the structure and behavior of a software application with the core business domain it serves. DDD focuses on breaking down complex business logic into smaller, more manageable parts by creating models that represent the real-world domain within the software.
Align Software with Business Logic:
DDD ensures that the software closely mirrors the business domain. This is achieved by fostering continuous collaboration between software developers and domain experts, who have deep knowledge of the business itself. This alignment reduces misunderstandings and makes the system easier to evolve over time
Ubiquitous Language:
One of the core principles of DDD is the use of a ubiquitous language—a shared vocabulary used consistently by both developers and domain experts. This common language minimizes communication gaps, ensuring that all stakeholders understand the same terms in the same way, improving clarity and reducing errors
Bounded Contexts:
DDD introduces the idea of bounded contexts, which are defined areas of the application where a specific domain model and ubiquitous language apply. This helps in managing the complexity of large systems by dividing the domain into smaller, distinct models, making each part easier to develop, maintain, and understand.
Strategic and Tactical Design:
DDD promotes both strategic design—which involves setting high-level business goals and ensuring the software's structure supports them—and tactical design, which includes practical techniques like designing entities, value objects, aggregates, and repositories. Together, these designs ensure that the software reflects the business needs and can handle complex requirements.
