Use case
 
Quote:
A use case is a description of a system’s behaviour as it responds to a request that originates from outside of that system.

 
A use case diagram presents the functionality provided by a system in terms of actors, their goals (represented as use cases), and any dependencies between those use cases.
 
Use case diagrams is one of the diagrams used in the Unified Modeling Language: UML.
 
A use case diagram is a graphical representation of the use cases.  
 
The analysis by which a use case is constructed is called use case analysis.
 
Quote:
The use case technique is used to capture a system's behavioral requirements by detailing scenario-driven threads through the functional requirements.

 
Quote:
Use cases describe the interaction between a primary Actor (the initiator of the interaction) and the system itself, represented as a sequence of simple steps.

 
Quote:
Actors are something or someone which exist outside the system under study, and that take part in a sequence of activities in a dialogue with the system to achieve some goal.

 
Quote:
Actors may be end users, other systems, or hardware devices. Each use case is a complete series of events, described from the point of view of the Actor.
