Domain-Driven Design: Concepts and Practices for Senior Developers Training Course

Foundational Concepts of Domain-Driven Design

• Core principles and the rationale behind adopting DDD
• Establishing ubiquitous language and fostering collaboration with domain experts
• Differentiating between core, supporting, and generic subdomains

Strategic Design and the Role of Bounded Contexts

• Defining the scope and responsibilities of bounded contexts
• Creating context maps and defining integration patterns
• Managing team structures, organizational boundaries, and data ownership

Tactical Patterns — The Building Blocks of the Domain Model

• Managing entities and their identity
• Utilizing value objects and enforcing immutability
• Structuring aggregates and defining transaction boundaries

Domain Services, Repositories, and Factory Patterns

• Determining the appropriate use of domain services versus application services
• Implementing repository patterns with an eye on persistence strategies
• Applying factory patterns for the creation of complex objects

Modeling Complex Behaviors and Invariants

• Designing invariants and rigorously enforcing business rules
• Event-driven modeling and the use of domain events
• Consistency strategies, including eventual consistency and sagas

Integrating DDD with Architectural and Engineering Standards

• Aligning DDD with microservices and modular monolith architectures
• API design, anti-corruption layers, and system integration strategies
• Validating domain logic through unit, integration, and contract testing

Implementing DDD Across Teams and Organizations

• Facilitating domain discovery workshops and Event Storming sessions
• Cultivating and maintaining a ubiquitous language across cross-functional teams
• Measuring outcomes and iterating on the domain model
