Virtual Domain-driven design

Getting started or advancing your Domain-Driven Design knowledge on your own can be a frustrating experience. Especially when you have so many questions to ask and exciting domains to model. How do you then grow if there is no one in your company or area that shares your passion for DDD? During this Virtual DDD meetup Zsofia and Kacper will share their experiences in building communities in Hungar...

Even with perfect naming and perfect code, it is hard to read the story of your domain straight out of it. You can be certain that you’ll have forgotten some of the nuances about the code the next time you see it. Or someone else sees it, because very few of us live our professional coding lives in an area where it’s only me ever handling the code. Someone is going to come back to your code - in f...

Within the community, there is been an ongoing discussion about the aggregate pattern. From Eric Evans perspective it is: An architectural pattern that enforces the consistency of a set of interrelated constraints, by defining a transactional boundary, a concurrency boundary, and a distribution boundary. A lot of people seem to have different perceptions, different explanations or altogether don't...

In the next SunDDDay discussion Alexey Zimarev and Marco Heimeshoff will join us and share their experience in building systems with CQRS and Event Sourcing. We will discuss what it exactly is, where it came from, what the strength and weaknesses are, when and how to use it, and how to design and maintain these systems. Join us through zoom webinar or follow the live youtube stream. You can intera...

Rebecca Wirfs-Brock, Paul Rayner en Alberto Brandolini will join us in this VDDD meetup and talk about what types of EventStorming there are, and what heuristics they use. Join us through youtube or zoom webinar in this discussion. You can interact with us and ask your questions through chat, or raise your hand in the zoom webinar and join us live to ask your questions fishbowl style!

On this first SunDDDay 26th May at 16:30 Central European Time (Amsterdam GMT +2), virtual DDD meetup will hold an online panel discussion where you can ask questions! Marco Heimeshoff, and Kenny baas-Schwegler (with a possible attendance by Zsófia Herendi and Trond Hjorteland) will discuss their experience with EventStorming and User story mapping for domain discovery. The two main questions are:...

DDD is about enabling developers and business owners to work together on a collaborative model, but how do you introduce the concept? In a world rife with acronyms and buzzword, people can be hesitant to try out new ideas, especially ones that involve changing the status quo. In this session, we'll discuss various techniques and ideas for introducing DDD to an organisation, with a focus on the nee...

In this SPA conference special, we will talk with Trond Hjorteland about if business capabilities are useful in DDD. The DDD community seems to consist of mostly technical people, or at least with some sort of hands-on programming experience, both now an back when the blue book was published. The decision to put the technical patterns at the start of that book was strategic (!) in that it was mean...

In this next virtual DDD meetup, João Rosa and Krisztina Hirth will discuss with us how impact mapping helps to find the possible solutions to achieve a measurable goal before you even know what to visualize. Also, how can you then combine it with other visualisation tools like EventStorming to guide your strategic design? In our industry, we have been assisting in digital transformations; the dig...

In this # VDDD meetup, we will talk with Ora Egozi-Barzilai and Evelyn van Kelle about their experience with socio-technical architecture. Socio-technical refers to the interrelatedness of social and technical aspects of an organization. Specific for this meetup we will discuss how teams affect the boundaries between bounded contexts and vice versa. These effects will give challenges in the way we...

Over more than 15 years ago, Eric Evans published the book Domain-Driven Design. The blue book, as it is called today, has a vast amount of knowledge on software architecture. As Paul Rayner once stated 'Every new idea on software architecture; you can already find somewhere in the blue book'. Because the knowledge is so fast to take in at one go, a lot of people who bought the book never finished...
