This course will give you a solid understanding of event sourcing and event modeling, two powerful approaches for designing and implementing software close to the domain of your business.
Instead of storing only the current state of your data, event sourcing captures every change as an immutable sequence of events. Event modeling builds on this by providing a structured way to design, visualize, and reason about your entire system through these events without going into detail about how the system is implemented.
Throughout this course, you will:
- Learn the fundamental concepts and terminology behind event sourcing and event modeling.
- Explore how commands, events, queries, and more work together to coordinate business processes.
- Learn how to implement event sourcing using functional patterns like deciders, views, sagas.
- Discover dynamic consistency boundaries (DCB) — a fresh way of thinking about consistency in event-sourced systems.
- Put everything into practice by modeling and implementing a simple review approval system step by step.
The focus of this course is on concepts and patterns, not on a specific tool or framework. Most examples are written in Kotlin/Java, but the ideas apply to any technology stack.
By the end, you’ll have the knowledge and confidence to apply event sourcing and event modeling in your own projects — and to participate in ongoing discussions about where these approaches are heading.
If you’re a software engineer, architect, or anyone interested in better ways to model complex systems, this course is for you.
