    PROOF: Produktmonitoring im Web
    (Datenbanksysteme für Business, Technologie und Web (BTW), 2011) Wartner, Christian; Kitschke, Sven
    Für Verbraucher, Händler und Hersteller ist die Beobachtung der Entwicklung von Angebotspreisen interessant, seien dies Preise von Produkten, Flügen oder Dienstleistungen. Wir präsentieren mit PROOF einen neuartigen Ansatz Produktmonitoring durchzuführen. PROOF ist ein erweiterbares System zum Integrieren und Analysieren von Webdaten. Die definierbaren Workflows erlauben unter anderem Anfrageoptimierungsund Objekt-Matching-Operationen, um eine hohe Datenqualität bei guter Performance zu erreichen.

    A smart link infrastructure for integrating and analyzing process data
    (Datenbanksysteme für Business, Technologie und Web (BTW 2015), 2015) Peukert, Eric; Wartner, Christian; Rahm, Erhard
    An often forgotten asset of many companies is internal process data. From the everyday processes that run within companies, huge amounts of such data is collected within different software systems. However, the value of analyzing this data holistically is often not exploited. This is mainly due to the inherent heterogeneity of the different data sources and the missing flexibility of existing approaches to integrate additional sources in an ad-hoc fashion. In this paper the Smart Link Infrastructure is introduced. It offers tools that enable data integration and linking to support a holistic analysis of process data. The infrastructure consists of easy to use components for matching schemas, linking entities, storing entities as a graph and executing pattern queries on top of the integrated data. We showcase the value of the presented integration approach with two real world usecases, one based on knowledge management in manufacturing from the LinkedDesign project and another one based on an agile software development process.
