Introduction

A use case is set of interactions between the external actors and the system under consideration with an objective of achieving specific goals as defined by the users of the system. A use case is used to capture the functional requirements of a particular system which in turn are used to capture the intended behavior of the system. The notion of an actor can be used to represent the external users, or the roles of the users, in fact even the systems other than the one under consideration are considered to be and actor.
