Domain-Driven Design (DDD) in Practice

Basics and Practical Use of Domain-Driven Design

All topics covered are considered against the background of a reference implementation for the intended application system "Flight Information System (FIS)" for an airline company. This means that all terms, concepts and procedures can be discussed in concrete terms using this practical case study. The participants deepen the training content in this case study through small exercises that, depending on the group of participants and their interests, can be completed on a flipchart, with a DDD/UML tool or as a demonstration in Java code. This covers various methods (e.g. Domain Storytelling), languages (e.g. Sculptor-DSL) and tools (e.g. Context Mapper) for the practical implementation of DDD.


Domain-Driven Design (according to E. Evans) is nowadays considered in two ways: As a basic development methodology for enterprise applications with complex business logic on the one hand and as a guideline for the logical design of microservices on the other.

In this training, participants will learn the basic terms and procedures of DDD. We will show you how the collaboration of business and software experts creates a long-term, sustainable model for an application system. But that's not all: We have implemented a concrete application system in the form of a reference implementation in Java / Jakarta EE, so that the participants gain an insight into the practical implementation of the DDD concepts. However, all training content is conceptually transferable to other programming languages and frameworks such as for example Spring (Boot).


Domain-Driven Design at a glance

  • Domain and Domain Model
  • Common business language (Ubiquitous Language)
  • Decomposition into Bounded Contexts
  • Realization through Building Blocks

Modeling the Domain

  • Determine the business matters (Domain Storytelling, Event Storming, OOA)
  • Detect and develop the Ubiquitous Language
  • Record the business logic (DSL of Context Mapper and Sculptor, UML, OOD)

Definition of Bounded Contexts

  • Vertical, business-driven slicing of the application
  • Subdomain (core vs. support vs. generic)
  • Bounded Context as a Self-Contained System (SCS)
  • Impact on the development process and the organization

Strategic Design

  • Context Mapping
  • Shared Kernel, Partnership
  • Customer/Supplier
  • Conformist, Anticorruption Layer, Published Language, Open Host Service
  • Separate Ways
  • Context Map and absence of cyclic dependencies (DAG)

Tactical Design

  • Building Blocks as design patterns for classes
  • Data: Attribute, Identifier, Entity, Value, Aggregate
  • Functionality: Factory, Repository, Service, Application
  • Communication: Gateway, Event Messaging, Data Transfer
  • Rich vs. Anemic Domain Model
  • Implementation using Jakarta EE

Software Architecture

  • Modular monolith, distributed system or microservices
  • Software technical effects (data storage, test data, method calls)
  • Clean Architecture to separate business knowledge and technologies
  • Standardized classes and their quality assurance

Teilnehmerkreis und Voraussetzungen

With this training offer, we are targeting companies or projects that are looking for an initial, comprehensive introduction to the topic of Domain-Driven Design. In this respect, we appeal equally to department/project managers, software architects, Java developers, business analysts and even QA/test employees. Knowledge of object orientation in general is desirable and experience in UML modeling or Java development is helpful, but not a requirement.
