    Generierung maßgeschneiderter Relationenschemata in Softwareproduktlinien mittels Superimposition
    (Datenbanksysteme für Business, Technologie und Web (BTW), 2011) Schäler, Martin; Leich, Thomas; Siegmund, Norbert; Kästner, Christian; Saake, Gunter
    Die Erstellung eines individuellen Programms aus einer Softwareproduktlinie (Programmfamilie) erfordert auf Anwendungsund Datenbankseite einen speziell angepassten und aufeinander abgestimmten Funktionsumfang. Die Modellierung maßgeschneiderter Relationenschemata stellt z.B. aufgrund der großen Anzahl an Programmen, die aus einer Produktlinie erstellt werden können, eine Herausforderung dar. Wir präsentieren einen Lösungsvorschlag zur Modellierung und Generierung von maßgeschneiderten Relationenschemata mittels Superimposition. Wir zeigen anhand einer realen, produktiv eingesetzten Fallstudie welche Vorteile unser Ansatz in den Bereichen Wartung und Weiterentwicklung erzeugt und welche Herausforderungen beispielsweise durch redundant definierte Schemaelemente existieren.

    Measuring program comprehension with functional magnetic resonance imaging
    (Software-engineering and management 2015, 2015) Siegmund, Janet; Apel, Sven; Kästner, Christian; Parnin, Chris; Bethmann, Anja; Saake, Gunter; Leich, Thomas; Brechmann, André
    We observed program comprehension with functional magnetic resonance imaging and found activation in brain areas related to working memory, divided attention, problem solving, and language processing.

    Eine Middleware-Architektur für mobile Informationssysteme
    (Informatik bewegt: Informatik 2002 - 32. Jahrestagung der Gesellschaft für Informatik e.v. (GI), 2002) Plack, Marco; Leich, Thomas
    Die Leistungsfähigkeit mobiler Geräte nimmt ständig zu. Neben moderner Hardware stehen mit GPS, GMS und UMTS leistungsfähige Techniken zur Lokalisierung und Kommunikation zwischen mobilen Systemen zur Verfügung. Für die Entwicklung von lokationsbasierten Diensten und mobilen Informationssystemen werden neben diesen Technologien moderne Softwarearchitekturen benötigt, die Funktionalitäten für eine einfache Verwaltung und einen einfachen Austausch von Informationen bereitstellen. In diesem Beitrag wird eine Middleware Architektur vorgestellt, die auf der Basis verschiedener Konzepte und Methoden eine einfache Anwendungsentwicklung für mobile Informationssysteme ermöglichen soll.

    Peer-Reviewing and Submission Dynamics Around Top Software-Engineering Venues: A Juniors’ Perspective
    (Software Engineering 2023, 2023) Alchokr, Rand; Krüger, Jacob; Shakeel, Yusra; Saake, Gunter; Leich, Thomas
    Research is an intrinsically challenging process full of obstacles. However, these obstacles may be more dominant for a specific group of researchers (such as junior researchers) compared to others. It is the responsibility of the community to pay close attention to those groups that may be struggling for unfair reasons and provide necessary support. Junior researchers are of high importance to the scientific community, and are defined as young researchers who have recently started their research career[ Li19]. Despite their importance, juniors may face impediments when starting their career that hinder their activities and motivation. For instance, collaboration aspects and peer-reviewing models can play a role. Junior researchers without a high reputation (e.g., via their co-authors) may be negatively impacted by reputation biases, and thus could have even more problems with publishing and building their reputation independently. In our study, we investigate what challenges junior researchers perceive when submitting their work to software-engineering venues with a high reputation.

    Program Comprehension and Developers’ Memory
    (INFORMATIK 2019: 50 Jahre Gesellschaft für Informatik – Informatik für Gesellschaft, 2019) Krüger, Jacob; Wiemann, Jens; Fenske, Wolfram; Saake, Gunter; Leich, Thomas
    In this extended abstract, we summarize our paper “Do You Remember This Source Code?”, published at the International Conference on Software Engineering 2018 [Kr18]. We discuss implications of our results on forgetting in the context of program comprehension, providing a more contextual perspective on our results compared to the original paper and a previous abstract [Kr19].

    SQL à la carte – Toward tailor-made data management
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Rosenmüller, Marko; Kästner, Christian; Siegmund, Norbert; Sunkle, Sagar; Apel, Sven; Leich, Thomas; Saake, Gunter
    The size of the structured query language (SQL) continuously increases. Extensions of SQL for special domains like stream processing or sensor networks come with own extensions, more or less unrelated to the standard. In general, underlying DBMS support o

    variED: An Editor for Collaborative, Real-Time Feature Modeling
    (Software Engineering 2023, 2023) Kuiter, Elias; Krieter, Sebastian; Krüger, Jacob; Saake, Gunter; Leich, Thomas
    This work was published in Empirical Software Engineering (EMSE) 26, 2 (2021) [Ku21]. Feature models are a helpful means to document, manage, maintain, and configure the variability of a software system. Various stakeholders in an organization may get involved in modeling the features in such a software system. Currently, collaboration in such a scenario can only be done with face-to-face meetings or by combining single-user feature-model editors with additional communication and version-control systems. While face-to-face meetings are often costly and impractical, using version-control systems can cause merge conflicts and inconsistency within a model. Advanced tools that solve these problems by enabling collaborative, real-time feature modeling, analogous to Google Docs or Overleaf for text editing, are missing. We describe the formal foundations of collaborative, real-time feature modeling; a conflict resolution algorithm; proofs that our formalization converges and preserves causality as well as user intentions; a prototype; and the results of an empirical evaluation to assess the prototype’s usability. Our contributions provide the basis for advancing existing feature-modeling practices to support collaborative feature modeling. Our prototype is considered helpful and valuable by 17 users, also indicating opportunities for new research directions.
