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

Introduction to Domain-Driven Design

• Underlying principles and the rationale for DDD
• Differentiating between core, supporting, and generic subdomains

Strategic Design and Bounded Contexts

• Establishing bounded contexts and defining their scope and responsibilities
• Context mapping strategies and integration patterns

Tactical Patterns — Core Components of the Domain Model

• Entities and the management of identity
• Value objects and the principle of immutability
• Aggregates and defining transaction boundaries

Domain Services, Repositories, and Factories

• Determining when to utilize domain services versus application services
• Repository patterns and considerations for persistence
• Factory patterns for managing complex object instantiation

Modeling Complex Behaviors and Invariants

• Designing invariants and enforcing business rules
• Consistency models: understanding eventual consistency and sagas

Integrating DDD with Architectural and Engineering Practices

• Aligning DDD strategies with microservices and modular monolith architectures
• API design, anti-corruption layers, and integration approaches
• Testing domain logic through unit, integration, and contract tests

Adopting DDD in Teams and Organizations

• Facilitating domain discovery workshops and Event Storming sessions
• Building and maintaining a ubiquitous language across distributed teams
• Measuring outcomes and refining the domain model iteratively
