The Event Delivery Network (EDN) in Oracle SOA Suite 11g provides a declarative way to use a publish/subscribe model. Business Events can be published and consumed without worrying about the underlying message infrastructure. Events can be published from different programming enviornments. Events provide another way of interaction within a SOA and offer a much more loosely coupled model.
