How can event modeling help you build better applications? Carl and Richard talk to Adam Dymitruk about Event Sourcing and Event Modeling, including the new book Understanding Eventsourcing. Adam talks about thinking through business workflows as an approach to event sourcing, where new data is constantly added, never modified. These data streams can then be modeled into different workflows following consistent patterns that make your application straightforward to build and maintain. It does take effort to change your thinking to the event source/model approach but with huge potential!
