Overview

This course equips you with the foundational knowledge to navigate Event Sourcing effectively and sets the stage for your continued learning journey. Event Sourcing is an architectural pattern revolutionizing data persistence in distributed applications, allowing you to preserve the complete history of changes in full fidelity rather than just the latest state.  

You will learn how Event Sourcing can be used with CQRS (Command-Query Responsibility Segregation) and why aggregates and projections are crucial in Event Sourcing architectures.

This training is practical and interactive.  The course is divided into lectures, group activities, and discussions, including hands-on coding for a basic event-sourced application. Active participation is required, as attendees should be willing to work in small groups with other attendees and contribute to remote modeling activities on a virtual whiteboard.
