The Event Canvas facilitates the design and refinement of a relationship. The Event Canvas only focuses on one event. The idea is to give an overview of all the involved CBCs of an event. In the above example, the focus is on a "sale" event. Within the workshop, the conclusion is that customer, employee, store and product are all involved whenever a sale happens. As such, the description could be, “A Customer comes into the store and buys one or more products from the employee.” This functions as an input for the NBR Matrix and NBR Form. There, we check if the event may produces multiple relations. This occurs whenever we find sparsity and redundancy in the relation or we find out a relationship is not unique.
