Thursday afternoon 14:00 - 16:00 CET (UTC+1)
Anton Stöckl and Dagmar de Haan
There are many ways to implement the Aggregate pattern from Domain-Driven Design:
We will discover as many of those variations as possible during the workshop.
Attendees will implement different variations of the same Aggregate in a “Code Koans” like fashion. For each variation there will be test cases and a skeleton which has to be filled with the missing code to make the tests green. We will supply a repository with Java Code.
Please prepare for the workshop:
An IDE for Java development (you can get IntelliJ CE here: https://www.jetbrains.com/idea/download/)
Clone our GitHub repo: https://github.com/MaibornWolff/aggregate-implementation-patterns-java (The default branch is “challenge” - please do yourself a favour and don’t look at the “solution” branch before the workshop!)
The only dependency is junit and our repo contains gradle files to help to install it (also for non IntelliJ IDEs).
We will split in groups and each group should do mob programming, swiching the driver for each coding challenge. For sure you can also work alone (if you absolutely prefer that).

Another important aspect for him is “socio-technical architecture” - a holistic approach to align IT architectures and autonomous agile development teams.
He loves to coach or mentor development teams, run workshops, and to write blog posts.
Some other important paradigms, architectural styles, and modeling methods he likes to apply:
Lately, he is working with Golang using a functional style of programming as much as possible and applicable.
