    Systemübergreifende Kostennormalisierung für Integrationsprozesse
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Böhm, Matthias; Habich, Dirk; Lehner, Wolfgang; Wloka, Uwe; Freytag, Johann-Christoph; Ruf, Thomas; Lehner, Wolfgang; Vossen, Gottfried
    Auf Grundlage der Vielzahl proprietärer Integrationssysteme ist zunehmend die Entwicklung von Ansätzen zur modellbasierten Generierung von Integrationsprozessen zu beobachten. Eine derartige Generierung bietet weiterhin die Möglichkeit der Auswahl des opt

    Web-prospector – An automatic, site-wide wrapper induction approach for scientific deep-web databases
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Mir, Saqib; Staab, Steffen; Rojas, Isabel; Freytag, Johann-Christoph; Ruf, Thomas; Lehner, Wolfgang; Vossen, Gottfried
    Wrapper induction techniques traditionally focus on learning wrappers based on examples from one class of Web pages, i.e. from Web pages that are all similar in structure and content. Thereby, traditional wrapper induction targets the understanding of Web

    Index- supported similarity join on graphics processors
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Böhm, Christian; Noll, Robert; Plant, Claudia; Zherdin, Andrew; Freytag, Johann-Christoph; Ruf, Thomas; Lehner, Wolfgang; Vossen, Gottfried
    The similarity join is an important building block for similarity search and data mining algorithms. In this paper, we propose an algorithm for similarity join on Graphics Processing Units (GPUs). As major advantages GPUs provide extremely high parallelis

    Value demonstration of embedded analytics for front office applications
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Nijkamp, Erik; Oberhofer, Martin; Maier, Albert; Freytag, Johann-Christoph; Ruf, Thomas; Lehner, Wolfgang; Vossen, Gottfried
    Users of front office applications such as call center or customer support applications make millions and millions of decisions each day without analytical support. For example, if a support employee gets a new support ticket and needs to decide how much

    Software as a service: Do it yourself or use the cloud
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Jacobs, Dean; Freytag, Johann-Christoph; Ruf, Thomas; Lehner, Wolfgang; Vossen, Gottfried
    In the Software as a Service (SaaS) model, a service provider owns and operates an application that is accessed by many businesses over the Internet. A key benefit of this model is that, by careful engineering, it is possible to leverage economy of scale

    Support 2.0: An optimized product support system exploiting master data, data warehousing and web 2.0 technologies
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Oberhofer, Martin; Maier, Albert; Freytag, Johann-Christoph; Ruf, Thomas; Lehner, Wolfgang; Vossen, Gottfried
    The proposed system integrates traditional and Web 2.0 based product support systems and uses master data management, data warehousing and text analytics functionality to send problem records to the person most capable to solve it, let it be an in-house t

    A Bayesian approach to estimating the selectivity of conjunctive predicates
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Heimel, Max; Markl, Volker; Murthy, Keshava; Freytag, Johann-Christoph; Ruf, Thomas; Lehner, Wolfgang; Vossen, Gottfried
    Cost-based optimizers in relational databases make use of data statistics to estimate intermediate result cardinalities. Those cardinalities are needed to estimate access plan costs in order to choose the cheapest plan for executing a query. Since statist

    MyMIDP and MyMIDP-client: Direct access to MySQL databases from cell phones
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Höpfner, Hagen; Schad, Jörg; Wendland, Sebastian; Mansour, Essam; Freytag, Johann-Christoph; Ruf, Thomas; Lehner, Wolfgang; Vossen, Gottfried

    Now it's obvious to the eye – Visually explaining XQuery evaluation in a native XML database management system
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Weiner, Andreas M.; Mathis, Christian; Härder, Theo; Hoppen, Caesar Ralf Franz; Freytag, Johann-Christoph; Ruf, Thomas; Lehner, Wolfgang; Vossen, Gottfried
    As the evaluation of XQuery expressions in native XML database management systems is a complex task and offers several degrees of freedom, we propose a visual explanation tool-providing an easily understandable graphical representation of XQuery-for track
