An Object-Oriented Approach to UML Scenarios Engineering and Code Generation

Object-oriented software development matured significantly during the past ten years. The Unified Modeling Language (UML) is generally accepted as the de facto standard modeling notation for the analysis and design of the object-oriented software systems. This language provides a suitable framework for scenario acquisition using use case diagrams and sequence or collaboration diagrams. In this paper, the authors suggest a requirement engineering process that composes UML scenarios to obtain a global description of a given service of the system and implementation code from the UML use case (service). They suggest four operators: sequential operator, concurrent operator, conditional operator and iteration operator to compose a set of scenarios that describe an use case of a given system.
