An Approach for Aspect-Oriented Use Case Modeling

摘要

A use case model is a specification of a system's requirements consisting in use cases, actors and relationships. A use case captures stakeholders concerns as required interactions between a system and its actors. Use case models may however include concerns that crosscut across several use cases. We propose an ?aspect? relation for the modularization and composition of these crosscutting concerns. The composition approach is formally established by mappings to Petri nets, and is implemented as an extension to an existing use case modeling tool.
