GOTO Technical Workshop

Building Event-Driven Systems with Axon Framework

Feb 2, 2023
12:30 - 16:30 CET
Copenhagen, Denmark

This hands-on session is comprised of three parts:

  1.  A brief orientation of Domain-Driven Design (DDD)

    How it enables us to devise software solutions to complex business problems in a systematic manner.

    You will learn:
    • What a domain model is, why establishing an ubiquitous language to foster a shared understanding of a domain matters, how to discover subdomains and design bounded contexts
    • The building blocks of a domain model - aggregates, entities, value objects, events and more.
    • Event-driven architectures, the CQRS and Event Sourcing concepts and their advantages, and the importance of eventual consistency and location transparency.

  2. Domain Modeling

    An example of DDD in practice, where a collaborative modeling technique known as Event Modeling is used to analyze and model a specific business domain, resulting in a blueprint for implementing a system that supports the gathered domain requirements.

  3. Axon Framework

    The domain model from part two is realized using the Axon Framework, which provides the foundations for applying DDD, CQRS and Event Sourcing in a JVM environment.

Through a number of exercises, you’ll implement an event-sourced application and key components (aggregates, and projections) and learn about commands, events and queries; finally, you’ll get an introduction to Axon Server and its function as an event store.

At the end of this workshop, you’ll have learned the essentials of DDD and modeling a business domain, as well as implementing an event-driven system based on a domain model.


Programming languages used throughout the course (basic knowledge of both is required):
  • Java (and the Spring framework)
  • Kotlin
The Axon Framework and Axon Server are utilized for the exercises and demonstrations.
