Domain Driven Design

In the course Domain Driven Design from SpiralTrain, participants learn to apply the principles of DDD to the design of applications.

Intro DDD

This module introduces Domain-Driven Design (DDD) and its key principles. Topics include domains, contexts, benefits and challenges of DDD, interviews with domain experts, and differentiating strategic versus tactical DDD. The differences from traditional design are also discussed.

Domain Understanding

Participants learn to identify domains such as core, supporting, and generic ones. Subdomains and the role of domain experts are explored through event storming, business rules, workflows, and constraints discovery.

Bounded Contexts

This module focuses on understanding bounded contexts and their role in separating different subdomains. Learners explore context maps, service interactions, and relationships such as partnership, shared kernel, customer-supplier, open host service, and anti-corruption layers.

Ubiquitous Language

Participants develop a shared language between developers and domain experts. Topics include message flowing, assigning responsibilities, collaborative modeling techniques like example mapping, and using documents and diagrams in DDD.

Building Domain Models

This module covers the construction of domain models, including entities, value objects, aggregates, and their roots. Learners work with repositories, factories, domain events, and services to capture business behavior and structure the domain.

DDD Application Architecture

This module explores architecture styles used in DDD such as layered and hexagonal architecture. Learners apply CQRS, integrate DDD into microservices and event-driven architectures, and examine connections with BDD. Common pitfalls and anti-patterns are also discussed.

Audience Course Domain Driven Design

The course Domain Driven Design is intended for software developers and software architects who want to use DDD in application development.

Prerequisites Course Domain Driven Design

Knowledge of Object Oriented Analysis and Design and design principles such as SOLID and DRY.

Realization Training Domain Driven Design

Presentations by the trainer using slides and demos that are alternated with practical exercises.

Certificate Domain Driven Design

After successfully completing the course, participants will receive a certificate of participation in Domain Driven Design.
