Use Case Modeling in Visual Paradigm for
UML
Use
Case Modeling is the process of describing the system behavior
of the target system from an external point of view. A use case
focuses on the external aspects of a system and captures the functional
and behavioral requirements of the system that help the users perform
their tasks. The UML notation of the use case is only an ellipse
with a Verb + Noun naming. It only indicates what action is performed
on a task that can achieve an observable user goal. Visual
Paradigm for UML provides a set of use case modeling toolset
for assisting the user to identify, document and prioritize the Use
Cases.

Filling in Use Case Description
Filling in the use
case description is very important in use case modeling.
Use case description includes descriptions of the use case,
preconditions, post conditions, flow of event and whatever
which is important in modeling the user goal. |

Conduct Use Case Scheduling
Use
Case Scheduling can help you to prioritize the use case.
It is very useful for planning the work in different phases
of the system development life cycle. The main philosophy
behind is to reduce the risks and uncertainty of the system
development project at easiest at possible, i.e. in other
words, the use cases are ranked according to the significances
to the successful completion of the system.

Elaborate Use Case using Activity Diagram
Sometimes sub-diagram
is useful for clarifying the tasks involved in the use cases.
For example, you can create an Activity Diagram under the
use case for documenting the business logic.

Generate documentation for your use case model
After you have finished documenting your use case model, you can generate the use case model into
HTML
or PDF
documentation. The generated document will show your use case model in detail, including
all use case description, sub-diagrams has been created under the use case.
