    Anforderungen an Datenbanksysteme für Multi-Tenancy- und Software-as-a-Service-Applikationen
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Aulbach, Stefan; Jacobs, Dean; Primsch, Jürgen; Kemper, Alfons
    Für Multi-Tenancy-Applikationen und Software as a Service (SaaS) stellen sich konventionelle Datenbanksysteme oftmals als ungeeignet heraus. In einem solchen Umfeld müssen Anforderungen, wie Erweiterbarkeit und Verfügbarkeit, trotz geringer Kosten für den

    An architecture for integrated operational business intelligence
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Christ, Ulrich
    In recent years, Operational Business Intelligence has emerged as an important trend in the Business Intelligence (BI) market. While sharing some obvious features with "traditional" data warehouse based BI, some of the requirements for the operational fla

    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
    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

    Bridging the gap between variability in client application and database schema
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Siegmund, Norbert; Kästner, Christian; Rosenmüller, Marko; Heidenreich, Florian; Apel, Sven; Saake, Gunter
    Database schemas are used to describe the logical design of a database. Diverse groups of users have different views on the global schema which leads to different local schemas. Research has focused on view integration to generate a global, consistent sch

    Bringing BLINK closer to the full power of SQL
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Stolze, Knut; Raman, Vijayshankar; Sidle, Richard; Draese, Oliver
    BLINK is a prototype of an in-memory based query processor that exploits heavily the underlying CPU infrastructure. It is very sensitive to the processor's caches and instruction set. In this paper, we describe how to close two major functional gaps in BL

    Building chemical information systems – the ViFaChem II project
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Tönnies, Sascha; Köhncke, Benjamin; Koepler, Oliver; Balke, Wolf -Tilo
    The interdisciplinary ViFaChem II project aims at providing a chemical digital library infrastructure for creating personalized information spaces. The value added services and scientific Web 2.0 techniques actively support chemical scientists and researc

    Continuous queries over data streams – Semantics and implementation
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Krämer, Jürgen
    Recent technological advances have pushed the emergence of a new class of data-intensive applications that require continuous processing over sequences of transient data, called data streams, in near real-time. Examples of such applications range from bus

    Easy tasks dominate information retrieval evaluation results
    (Datenbanksysteme in Business, Technologie und Web (BTW) – 13. Fachtagung des GI-Fachbereichs "Datenbanken und Informationssysteme" (DBIS), 2009) Mandl, Thomas
    The evaluation of information retrieval systems involves the creation of potential user needs for which systems try to find relevant documents. The difficulty of these topics differs greatly and final scores for systems are typically based on the mean ave
