Data Centric Software Systems Research Group

Data centric software systems support the communication, processing and analysis of large, heterogeneous data volumes and streams in modern application scenarios. These include complex IT landscapes, online platforms, cyber-physical systems and software-based networks. These systems must function efficiently, scalably, reliably and trustworthily at all times.

Members of the Data Centric Software Systems (DSS) Research Group at the Institute of Applied Research pool their competencies at the application and system level and develop innovative and viable solutions together with partners from industry and academic research.
