SCENARIO-BASED VISUAL ANALYSIS FOR STATIC AND DYNAMIC MODELS IN OOA

摘要

An analysis method named “Scenario-based Visual Analysis(rnSVA)“ is proposed for supporting the early stage ofrnobject-oriented analysis(OOA) for software development.rnIn this method, objects, actions and relations are extractedrnfrom the scenario description as collaborators of the system.rnVisual sequential representation of the scenario suggestrnan analyst to identify object groups and action groups.rnThese groups are to become static class diagrams, andrndynamic sequence ones. A visual editor to support thisrnmethod has been developed for representing extracted collaboratorsrnin a schematic form that helps an analysts’ intuitiverndecision for forming a class structure in OOA. Anrnevaluation of the method and the editor was performed forrnthe elevator problem and a promising result has been obtained.
