    A data model for software engineering databases is presented. On the basis of an entity-relationship-approach, the model provides special features for complex objects, consistency, vague or incomplete information, variants, and versions. A prototype of a database system based on this model is being implemented.Das Modell einer Datenbank für Anwendungen in der Softwaretechnik wird vorgestellt. Es basiert auf einem Entity-Relationship-Ansatz, enthält aber zusätzliche Modellierungsmittel für komplexe Objekte, Konsistenzsicherung, vage bzw. unvollständige Informationen, Versionen- und Variantenverwaltung. Ein Prototyp eines Datenbanksystems, welches mit diesem Modell arbeitet, wlrd implementiert

    IDR : a participatory methodology for interdisciplinary design in technology enhanced learning

    One of the important themes that emerged from the CAL’07 conference was the failure of technology to bring about the expected disruptive effect to learning and teaching. We identify one of the causes as an inherent weakness in prevalent development methodologies. While the problem of designing technology for learning is irreducibly multi-dimensional, design processes often lack true interdisciplinarity. To address this problem we present IDR, a participatory methodology for interdisciplinary techno-pedagogical design, drawing on the design patterns tradition (Alexander, Silverstein & Ishikawa, 1977) and the design research paradigm (DiSessa & Cobb, 2004). We discuss the iterative development and use of our methodology by a pan-European project team of educational researchers, software developers and teachers. We reflect on our experiences of the participatory nature of pattern design and discuss how, as a distributed team, we developed a set of over 120 design patterns, created using our freely available open source web toolkit. Furthermore, we detail how our methodology is applicable to the wider community through a workshop model, which has been run and iteratively refined at five major international conferences, involving over 200 participants

    This study aims to explore the dynamics of collaborative work in global software development projects. The study explored the nature of collaboration, the patterns of collaborative behaviors in different tasks in computer science, and the impact of the tasks to the collaboration among students. Four different collaborative software development tasks were assigned to the globally distributes teams. The study used data from 230 students from five universities, namely Atilim University (Turkey), Middle East Technical University (Turkey), Universidad Tecnológica de Panamá (Panama), University of North Texas (US), and Middlesex University (UK). The findings involve the recommendations for building effective collaborative working environments and guidelines for building collaborative virtual communities

    Automating embedded analysis capabilities and managing software complexity in multiphysics simulation part I: template-based generic programming

    Full text link
    An approach for incorporating embedded simulation and analysis capabilities in complex simulation codes through template-based generic programming is presented. This approach relies on templating and operator overloading within the C++ language to transform a given calculation into one that can compute a variety of additional quantities that are necessary for many state-of-the-art simulation and analysis algorithms. An approach for incorporating these ideas into complex simulation codes through general graph-based assembly is also presented. These ideas have been implemented within a set of packages in the Trilinos framework and are demonstrated on a simple problem from chemical engineering
