Transforming Use Case Maps to the Core Scenario Model Representation Yong Xiang Zeng Thesis submitted to the Faculty of Graduate and Postdoctoral Studies in partial fulfillment of the requirements for the degree of Master of Computer Science Under the auspices of the Ottawa-Carleton Institute for Computer Science University of Ottawa Ottawa, Ontario, Canada June 2005 © Yong Xiang Zeng, Ottawa, Canada, 2005 Abstract Scenarios describe system functionalities and, when supplemented with performance annotations, provide a basis for performance analysis. This thesis presents a Core Scenario Model (CSM), which includes common scenario information in the Use Case Maps (UCM) notation and in UML 2.0 activity diagrams and interaction diagrams. The intent is to enable automatic transformations from a given scenario model to CSM, and then from a CSM model to performance models, hence enabling performance analysis early in the development process. CSM captures scenarios, performance, and deployment information, and is flexible enough to support multiple input scenario notations and output performance languages. The thesis also includes a transformation from UCM models to CSM. Such automatic transformation enables the quick generation of performance models, ready to be analyzed. The results from performance analysis can be traced back to improve design decisions and any changes in design can be updated in performance models quickly through re-generation.
