ITT 2021 | A practical introduction to DDD, CQRS & Event Sourcing

After several in-depth talks about Event Sourcing, I realized that there’s a large group of developers that may have heard about Domain-Driven Design, Command-Query Responsibility Segregation and Event Sourcing, but have not really connected the dots yet. So in this talk, I’d like to take a practical example of a simple domain and gradually introduce functional requirements to see how the principles behind DDD affect the way your entities are going to protect the business rules. After that, I’ll introduce some real-world non-functional requirements and see if and how Event Sourcing and/or CQRS may or may not help to accomplish those.
