Domain Driven Design (DDD) Training in Dublin, Ireland

Domain Driven Design (DDD) training teaches professionals how to create complex software systems by focusing on the core domain and its logic. The course covers key DDD concepts such as entities, value objects, aggregates, and bounded contexts to help design scalable, maintainable architectures. Participants learn to collaborate with domain experts to capture the intricacies of the business problem and map them into software models. The training also delves into tactical DDD patterns like repositories, factories, and services for organizing code effectively. By completing Domain Driven Design training, professionals gain the skills to develop robust systems aligned with business needs, fostering a deeper understanding of both technology and business processes.

Introduction to Domain-Driven Design and Key Concepts

• Introduction to Domain-Driven Design (DDD)

• What is DDD and why is it important for complex systems?

• DDD’s role in modeling business domains and aligning software with business strategy.

• Overview of DDD terminology and principles (e.g., Ubiquitous Language, Entities, Aggregates).

• Ubiquitous Language and Communication

• Importance of a shared language between developers and domain experts.

• Creating a Ubiquitous Language to ensure consistent communication across teams.

• How to evolve the Ubiquitous Language throughout the project lifecycle.

• Hands-On Exercise

• Entities and Value Objects

• Understanding the difference between entities and value objects.

• Designing and modeling entities to represent business concepts with unique identifiers.

• Using value objects to represent concepts that do not require identity.

• Hands-On Exercise

• Aggregates and Aggregate Roots

• The role of aggregates in DDD: Encapsulating domain logic and ensuring consistency.

• Identifying aggregate roots and defining boundaries.

• Managing transactional consistency within aggregates.

• Hands-On Exercise
