| Abstract: |
A use case represents a unit of the functionality specification of a
system. Industrial object-oriented projects have applied use cases
to capture user requirements. Use cases can be used throughout the whole
process of object-oriented software development [14].
But, the problem of how to write use cases is still puzzling even
software experts [6]. It reflects the lack of a systematic
approach to capturing use cases. The set of use cases in a use case
model is unstructured regarding the structure of the problem addressed
by an application. This paper presents a notion of a
use case pattern and proposes using a use case pattern to guide
use case capturing. A use case pattern encodes reusable knowledge on the
structure and function of a specific class of applications. It guides the
work of use case gathering. We illustrate the approach to use case
modeling with several use case patterns. |
