BTW2019 - Datenbanksysteme für Business, Technologie und Web - WorkshopbandBTW2019 - Datenbanksysteme für Business, Technologie und Web - Workshopband 

BTW 2019 – Workshopband Meyer, Holger; Ritter, Norbert; Thor, Andreas; Nicklas, Daniela; Heuer, Andreas; Klettke, Meike

First Investigations of the Vector Supercomputer SX-Aurora TSUBASA as a Co-Processor for Database Systems 

BTW 2019 – Workshopband Pietrzyk, Johannes; Habich, Dirk; Damme, Patrick; Lehner, Wolfgang
The hardware landscape is currently changing from homogeneous multi-core systems towards heterogeneous systems with many different computing units, each with their own characteristics. This trend is a great opportunity for database systems to increase the overall performance if the heterogeneous resources can be utilized ...

Angepasstes Item Set Mining zur gezielten Steuerung von Bauteilen in der Serienfertigung von Fahrzeugen 

BTW 2019 – Workshopband Spieß, Marco; Reimann, Peter
Qualitätsprobleme im Bereich Fahrzeugbau können nicht nur zum Imageverlust des Unternehmens führen, sondern auch mit entsprechend hohen Kosten einhergehen. Wird ein Bauteil als Verursacher eines Qualitätsproblems identifiziert, muss dessen Verbau gestoppt werden. Mit einer Datenanalyse kann herausgefunden werden, welche ...

Query Planning for Transactional Stream Processing on Heterogeneous Hardware: Opportunities and Limitations 

BTW 2019 – Workshopband Götze, Philipp; Pohl, Constantin; Sattler, Kai-Uwe
In a heterogeneous hardware landscape consisting of various processing units and memory types, it is crucial to decide which device should be used when running a query. There is already a lot of research done for placement decisions on CPUs, coprocessors, GPUs, or FPGAs. However, those decisions can be further extended ...

Konzeption und Umsetzung einer DSL zur Informationsfusion auf verteilten heterogenen Graphen 

BTW 2019 – Workshopband Kern, Alexander
Informationsintegration ist das Zusammenführen von Informationen aus verschiedenen Quellen. Dadurch soll eine effektivere Nutzung der Daten erreicht werden, als durch die Arbeit mit den einzelnen Quellen möglich ist. Allerdings ist Informationsintegration ein hochkomplexes Problem. Es umfasst neben der Duplikatserkennung ...

An Actor Database System for Akka 

BTW 2019 – Workshopband Schmidl, Sebastian; Schneider, Frederic; Papenbrock, Thorsten
System architectures for data-centric applications are commonly comprised of two tiers: An application tier and a data tier. The fact that these tiers do not typically share a common format for data is referred to as object-relational impedance mismatch. To mitigate this, we develop an actor database system that enables ...

Software solutions for form-based, mobile data collection – A comparative evaluation 

BTW 2019 – Workshopband Steinberg, Markus; Schindler, Sirko; Klan, Friederike
Many citizen science projects rely on their contributors going to the field and collecting data. Due to their wide availability and increasing capability, modern mobile devices have become an indispensable tool to ease the collection process. Projects can publish mobile apps, that allow contributors to easily collect ...

Policy-based Authentication and Authorization based on the Layered Privacy Language 

BTW 2019 – Workshopband Wilhelm, Sebastian; Gerl, Armin
In 2018 the General Data Protection Regulation (GDPR) has been enforced providing a new legal framework with rules and regulations for processing personal data. The requirement for distinguishing between purposes has been introduced, leading to the necessity of adapting existing authentication and authorization processes. ...

Skew-resilient Query Processing for Fast Networks 

BTW 2019 – Workshopband Ziegler, Tobias; Binnig, Carsten; Röhm, Uwe
Motivation: Scalable distributed in-memory databases are at the core of data-intensive computation. Although scaling-out solutions help to handle large amounts of data, more nodes do not necessarily lead to improved query performance. In fact, recent papers have shown that performance can even degrade when scaling out ...

Quality Indicators for Text Data 

BTW 2019 – Workshopband Kiefer, Cornelia
Textual data sets vary in terms of quality. They have different characteristics such as the average sentence length or the amount of spelling mistakes and abbreviations. These text characteristics have influence on the quality of text mining results. They may be measured automatically by means of quality indicators. We ...
