Learn to build rich domain models and use advanced tactical patterns
Summary
In this training we’ll teach you how to implement a Domain-Driven application in Java from scratch.
Do you want to learn how to use tactical patterns to implement a full and rich domain model? Are you curious how you can leverage tactical patterns to implement business rules, to express the language of domain experts explicitly? And do all of this while building a full application, not small isolated examples?
Then this is the training for you. We’re tackling questions that people still have after reading about tactical patterns:
- When and why do I use these patterns?
- How can I explicitly model business rules?
- How do these patterns work together in a Domain-Driven application?
- What does a good working Domain-Driven application look like?
We’ll start with the basic building blocks of DDD. Basic as in these building blocks are the basis of a good Domain-Driven applications. Then we’ll teach you how, when and why you should use a certain pattern, and we’ll add more advanced patterns along the way.
You’ll use what you’ve learned to implement a working DDD application yourself.
Experienced DDD practitioners will give feedback on your implementation. We’ll also provide an example solution and how we came to this example solution, so you can further evaluate your own solution.
At the end of the training you’ll have working knowledge on how to implement Domain-Driven Design in Java and will have implemented a full application yourself.

Learning outcomes
- you know what the tactical patterns (value object, entity, specification, repository, aggregate,…) are, when to use which pattern and how to implement them in Java
- You know how to setup, structure and implement a Domain-Driven application
- You know how to go from scenarios and domain knowledge to a working application
Audience
This training is aimed at programmers.
Practical
This training is divided in 2 main parts:
- Interactive theory sessions. These are remote group sessions where the trainers will introduce new theory, explain the domain and introduce new implementation exercises.
- Exercises that you need to implement on your own, at your own pace. After each exercise we’ll provide an evaluation session where we look at and evaluate your implementation.
The interactive sessions will be recorded if you can’t make it, but it’s highly recommended to join. This will allow you to ask questions, participate in discussions and group activities. The goal after every session is that you fully grasp the theory and are ready to apply it in the next set of implementation exercises.
After each session you get implementation exercises as homework. You will need 2-4 hours per session to implement the homework. To get the most out of this workshop, it’s really important that you do the exercises the best you can.
Experienced DDD practitioners will evaluate what you’ve implemented at the start of every next session. This will be the time to discuss the outcomes and answer possible questions you may have.
a note on pairing
We find it’s really valuable for participants if they pair or mob with other participants. If you’re interested in this, we’ll help you set this up.
Prerequisites
- Zoom (or access to the Zoom client in your browser).
- Miro (or access to the Miro client in your browser).
- Working setup for Java, this includes an editor and git.
Prior knowledge
- You have experience working in Java. This is not a training to learn the programming language.
- You don't need knowledge of Tactical Domain-Driven Design.
Prior to the workshop
In the week before the workshop, we’ll send out the practical setup. This includes cloning a template application, making sure it compiles and the tests run.
We’ll also plan a slot to help you out with the setup if needed.
Frequently Asked Questions (FAQ)
1. What is the schedule for the workshops?
Each workshop session is scheduled once a week. 1 Session last 3.5 hours with regular breaks in between.
2. When can I complete the homework assignments?
You have the flexibility to complete the homework at your convenience throughout the week. Whether it's immediately after a session or any other time that fits into your schedule, you have the freedom to choose.
3. Do I need to submit the homework on a specific time?
No, submitting the homework on time is not mandatory. However, we highly encourage participants to complete the assignments before the next session. We review the homework during the subsequent session, making the course more valuable for those who actively engage in the assignments.
4. How do we review the homework?
During each session, we dedicate time to review and discuss the homework assignments in small breakout groups with regular time of a facilitator. This interactive review process allows participants to receive feedback, ask questions, and deepen your understanding of the concepts covered in the workshop.
We discuss the most prominent questions in a bigger group after the breakout group discussions.
5. Do you provide the solution to the homework as well?
Yes, after each session we submit a solution that you can look at. We only provide that solution at the beginning of the next session.
6. What if I have questions about the homework during the week?
If you have any questions or need clarification on the homework assignments during the week, feel free to reach out to us.
7. Home much time do I need spend on the homework?
You should be able to complete most homework exercises in 2-4 hours.
8. How well do I need to know Jave?
The focus of the workshop is about Domain-Driven Design in Java, not on Java specifically. So that means you don't need to be an expert in the programming language to get the most of the course.
What participants say about this workshop
"The course was incredibly insightful while also a demanding one. It involved group zooming sessions with huge miro board, dozen of hands on exercises, and constant collaboration. Additionally we were tasked with homeworks.
This workshop answered to many open questions I had about tactical domain modelling. The practical approach made it easy to apply these concepts to real-world problems. The scope was really broad, from modelling to domain objects, constraints, architecture, bounded context, and mapping.
Thank you for the excellent instruction and for providing such a valuable learning experience! Without a doubt one of the best online workshops I ever had. Real gold."
- Renato Ivančič, Senior Software Engineer at CREALOGIX Group - 2024
"I enjoyed the collaboration and the discussions with the other people to get a different perspective. The development team first has to master the mindshift towards a bounded context and the associated building blocks. DDD helps to write more maintainable software, and that will have a big impact on the long term."
- workshop participant 2023
"I liked the frequency of the session to "digest" the theory. This workshop will have an impact on my mindset and approach: I will avoid usual technical layered architecture and focus first on understanding the business domain and apply it via the patterns presented."
