- KonferenzbeitragWeb-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, IsabelWrapper 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
- KonferenzbeitragIndex- 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, AndrewThe 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
- KonferenzbeitragSystemübergreifende 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, UweAuf 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
- KonferenzbeitragSupport 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, AlbertThe 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
- KonferenzbeitragValue 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, AlbertUsers 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
- KonferenzbeitragA 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, KeshavaCost-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
- KonferenzbeitragSoftware 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, DeanIn 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
- KonferenzbeitragEfficient verification of B-tree integrity(Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Graefe, Goetz; Stonecipher, RyanThe integrity of B-tree structures can become compromised for many reasons. Since these inconsistencies manifest themselves in unpredictable ways, all commercial database management systems include mechanisms to verify the integrity and trustworthiness of
- KonferenzbeitragATE: Workload-oriented DB2 tuning in action(Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Wiese, David; Rabinovitch, Gennadi; Reichert, Michael; Arenswald, Stephan
