+
+
+**Intent:** Send and notify state changes of your objects to other applications using an Event-driven Architecture.
+
+
+
+**Applicability:** Use an Event-driven architecture when
+
+* you want to create a loosely coupled system
+* you want to build a more responsive system
+* you want a system that is easier to extend
+
+**Real world examples:**
+
+* A Loan Application has been accepted/rejected (commercial business).
+* A new Rostering Schedule is ready for distribution to all crew (Airline Management System).
+* An Illegal Trade Pattern has been detected (Trading Fraud Detection System).
+* A simulated car has hits another simulated car (Commercial Racing Game).
+* A robot has reached its destination (Real Time Warehouse Management System).
+* A HTML message has been received (Web Server).
+* A key has been pressed (Text Editor).
