Write short note on Events

Events consist of inputs, interrupts, decisions and actions performed by any external device or users. Every event always has a sender and receiver. In most of cases sender and receives are same object. A state with no a predecessor and successor are ambiguous and care would be taken to represent initiations and termination of the events.  Events that have same effect on control flow must be grouped together even if value differs. The events are to be allocated to object classes that send or receive it.

Most of design issues of systems are concerned with steady-state behaviour of system.

However, system design phase must also address the initiation and finalization of system. This is addressed by a set of new uses cases known as administration use cases
