This research group is part of a larger research effort in Berlin between the Technische Universität Berlin, the Hasso-Plattner-Institut (Potsdam) and Humboldt-Universität zu Berlin
This DFG-Graudate SChool SOAMED (Service-orientierte Architekturen zur Integration Software-gestützter Prozesse am Beispiel des Gesundheitswesens und der Medizintechnik) investigates various aspects of service oriented architectures in the context of medical systems.
The DBIS research group investigates various aspects of data management and workflow execution as a member of the Graduate School METRK (Model-Based Development of Technologies for Self-Organizing Decentralized Information Systems in Disaster Management).

Relational database technology has been researched for decades and is widely used in production system. Utilizing this experience most approaches build on top of relational DBMS to manage RDF data. However, RDBMS have not been optimized to manage graph-like data, but tabular data. Additionally, RDF comes with its own query language (SPARQL) which especially allows to retrieve subgraphs from the RDF data. Considering the results of the Berlin SPARQL Benchmark we think that there is most likely room for improving the query processing within existing RDF repositories. Hereby, we focus on three areas: physical management of the RDF data, its indexing, and query optimization.
Das Projekt hat die prototypische Implementierung einer Datenbank- und Workflow gestützten IT Umgebung des Massenspektrometrie-Gerätes (LTQ-FT) zum Ziel.
This project investigates how to take andvantage of the new hardware developments by adapting existing query optimization and query execution techniques.
Das Projekt DESWAP entwickelt eine Entwicklungsumgebung für Semantic-Web-Anwendungen, bei der existierende Software-Bausteine gefunden und mit einer Anwendungslogik integriert werden.
Durch Kombination von strukturierten und unstrukturierten Netzwerken entsteht „The Query Web“, eine neue Architektur für Peer-to-Peer-Netze, die relativ unempfindlich auf Veränderungen des Netzes reagiert.
