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, we suggest a requirement engineering process that composes UML scenarios for obtain a global description of a given service of the system and implementation code from the UML use case (service). We suggest four operators: sequential operator, concurrent operator, conditional operator and iteration operator to compose a set of scenarios that describe a use case of a given system. We developed algorithm and tool support that can automatically produce a global sequence diagram representing any way of composing them and to offer a code generation of sequence diagram resulting.
