Domain-Driven Design: Building Complex Software with Clarity and Consistency

🏢Domain-Driven Design (DDD) ensures software represents the business and its functionality clearly through the code.

🌐DDD emphasizes the use of a ubiquitous language to foster shared understanding and consistent communication between business and engineering teams.

🗺️Strategic design in DDD involves identifying subdomains and creating a clear map of how they interact with each other.

📦Tactical design in DDD focuses on refining domain models, including entities, value objects, aggregates, repositories, and services.

🏢➡️🔁Hexagonal architecture is recommended for implementing DDD, ensuring separation of concerns and facilitating flexibility.

What is the goal of Domain-Driven Design (DDD)?

—The goal of DDD is to build software that accurately represents the business and its functionality, ensuring clarity and consistency.

How does DDD promote shared understanding between business and engineering teams?

—DDD promotes the use of a ubiquitous language, ensuring that all team members use the same terms and concepts when discussing the software.

What is strategic design in DDD?

—Strategic design in DDD involves identifying subdomains and establishing a clear map of their interactions to ensure a holistic understanding of the system.

What is tactical design in DDD?

—Tactical design in DDD focuses on refining domain models, including entities, value objects, aggregates, repositories, and services, to accurately represent the business logic.

What is hexagonal architecture and why is it recommended for DDD implementation?

—Hexagonal architecture is an architectural pattern that facilitates the implementation of DDD by separating the core business logic from external dependencies, promoting flexibility and testability.
