An event is a message sent because an activity occurred in a business environment. Mediator can both subscribe to and raise business events. You can subscribe to a business event that is generated when a situation of interest occurs. For example, you can subscribe to an event that is generated when a new customer is created and then use this event to start a business process, such as sending a confirmation email. Similarly, you can generate business events when a situation of interest occurs. For example, after a new customer profile is created, you can generate a customer-created event.
