    Supporting Requirements Engineering and Development with Event Modeling - an Overview
    (Modellierung 2022, 2022) Copei, Sebastian; Emme, Clemens; Freiherr von Künßberg, Maximilian; Malik, Adam; Nolte, Natascha; Norbisrath, Ulrich; Zündorf, Albert
    Workflow based systems are frequently modeled using BPMN diagrams for requirements engineering and UML diagrams for analysis and design. While such diagrams are great input for the software development, non-ICT people like domain experts, customers, end users or business people usually do not understand their content. Therefore, non-ICT people are frequently not able to contribute to these diagrams nor able to identify missing or incorrect parts. This paper proposes the very informal event storming approach as a means to involve users into the requirements engineering activities. We then refine the event storming results via Event Modeling by adding elaborated user interface scenarios. These event models then serve as input for integrated data modeling steps.

    Zur Identifikation von Strukturanalogien in Datenmodellen
    (Wirtschaftsinformatik: Vol. 47, No. 2, 2005) Fettke, Peter; Loos, Peter
    On the one hand, data models decrease the complexity of information system development. On the other hand, data models causes additional complexity. Recently structural analogies are discussed as instruments reducing the complexity of data models. This piece of research presents a procedure to identify structural analogies in data models and demonstrates its performance by analyzing Scheer’s reference model for industrial enterprises (Y-CIM-model). The proposed procedure is based on formalizing data models within set theory and uses a quantitative similarity measure. The obtained results show both identical and very similar information structures within the Y-CIM-model. Furthermore, ways of dealing with the identified structural analogies are discussed from an analysis and software design perspective.
