How to Draw Use Case Diagram for Final Project CS619 Help

Post by ALI RAZA » Tue May 08, 2018 9:02 am

A use case diagram at its simplest is a representation of a user's interaction with the system that shows the relationship between the user and the different use cases in which the user is involved.
Use case diagrams are usually referred to as behavior diagrams used to describe a set of actions (use cases) that some system or systems (subject) should or can perform in collaboration with one or more external users of the system (actors). Each use case should provide some observable and valuable result to the actors or other stakeholders of the system.

Sample Use Case

An actor specifies a role played by a user or any other system that interacts with the subject. In Alistair Cockburn's book “Writing Effective Use Cases” (2) Actors are further defined as follows: Primary Actor: The primary actor of a use case is the stakeholder that calls on the system to deliver one of its services.
Sample Use Case
System Boundary is line in which all processes of System are Working . The boundary in which system performs Actions .

Relationships
There are several types of relationships that may appear on a use case diagram:
An association between an actor and a use case
An association between two use cases
A generalization between two actors
A generalization between two use cases
Associations are depicted as lines connecting two modeling elements with an optional open-headed arrowhead on one end of the line indicating the direction of the initial invocation of the relationship. Generalizations are depicted as a close-headed arrow with the arrow pointing towards the more general modeling element.
