When you have a highly collaborative application, with many different people changing the same data, how can we help people feel safe? What does it take to create a world where a user can make an error, say "oops!" and go back to safety? Join us as we take a high level look at why you shouldn't use CRUD, and why you should use a task-based UI. We'll explore the conceptual differences between 'Undo' and 'Cancel', and even touch on Event Sourcing.
