OKTech Study Session - DDD part 3: Putting the model into practice

Are you a software engineer who enjoys digging into new ideas, practices, and patterns that strengthen your craft? Join us for the next OKTech Study Session, a gathering for engineers who don’t just code, but want to understand the why and how behind solid software design.

In this third session, we’ll bridge the gap between problem space and solution space. Building on the domain model from Part 2, we’ll explore how to translate it into working code using DDD’s tactical patterns: Entities, Value Objects, Aggregates, and Invariants. Through practical examples, we’ll see how to preserve business meaning in code and ensure it stays aligned with the domain over time.

Whether you’re completely new to DDD or looking to sharpen your understanding, these sessions are designed to help you take your first steps toward using DDD in practice. It is not a problem to join only one of the sessions, but this series builds on previous sessions. Therefore we encourage you to join all three to get the most out of it.
