Designing and Implementing Aggregates - Mariusz Gil

Domain-Driven Design, Aggregates and EventStorming - An Evening with Mariusz Gil
Aggre-what? Lots of talking about aggregates in the DDD world, yet one of the questions we receive more often at workshops and during events is... what is an aggregate "exactly"? How do you design a good aggregate?
DDD expert Mariusz Gil's got the answer. Let's find out in this presentation, based on a concrete and real example, where you can ask questions through the RUclips chat in real-time.
👉 Title
Designing and Implementing Aggregates
📝 Abstract
One technique of the Domain-Driven design approach is the Aggregate concept. This well-applied pattern of tactical DDD allows us to safely perform complex data modifications in a system, making it bulletproof regarding data consistency and correctness.
However, designing such objects is sometimes problematic, as is discovering important immutables whose consistency we should guarantee.
During the session, we will go through the process of analyzing, modelling and implementing a sample aggregate using a concrete example.
We will also learn about principles, good and bad modelling practices, helpful heuristics, and facilitating the whole analysis and modelling process.
As usual, you'll have a chance to interact with Mariusz and your fellow participants by joining the RUclips chat during the live streaming. Plenty of space for your questions: let's make this interactive!

29:17 First approach
32:21 Second approach
40:57 Third approach
50:00 Different approach
52:11 So... what is an aggregate?

[@zebcode]

21 minutes and we're still discussing the problem. I think it should have been kept much simpler so that we can get to the topic of the video. I really came here to learn about aggregates.

very well explained, thanks Mariusz, it was super clear!
Thanks also Avanscoperta to bring this talk to us 🎉
