This event is particularly relevant for researchers and professionals in database systems, distributed computing, and data-intensive applications.

Abstract: Data management systems research focuses on improving human and technical efficiency for performing data analysis tasks. In this presentation, I describe selected research contributions to achieve that goal. I first highlight work on using query feedback in order to improve the cardinality model of a relational query optimizer. I then will discuss how the research vision of the Stratosphere research project at TU Berlin lead to the creation of the data stream processing system Apache Flink. As a third contribution, I will discuss how fractal space-filling curves can be used to efficiently process multidimensional range queries. I will conclude by giving an outlook on NebulaStream, a novel data processing system for handling massively distributed data streams on heterogeneous devices.

Bio: Volker Markl is a German Professor of Computer Science and co- Director of the Berlin Institute for the Foundations of Learning and Data (BIFOLD). He leads the Chair of Database Systems and Information Management (DIMA) at TU Berlin and the Intelligent Analytics for Massive Data Research Department at the German Research Center for Artificial Intelligence (DFKI). He is a database systems researcher, conducting research at the intersection of distributed systems, scalable data processing, and machine learning.
