Background

About Steffen Zeuch

During my studies, I specialized on database technology and Business Intelligence. I am familiar with the Business Intelligence concepts starting with modeling business and ETL processes, transforming the concepts to data layouts, and storing and querying them in a distributed system. Due to my work and internships at the SAP database department, I am familiar with modern in-memory databases. In the context of my master thesis at SAP, I developed a data structure for data items with infrequent access patterns that affects the entire database stack ranging from SQL query transformation to bit-level organization. My research as Ph. D. student focuses on multicore and main memory challenges for data access in query optimization. My work on accelerating tree structures using SIMD instructions appeared at EDBT 2014. Furthermore, I proposed a Query Task Model that opens a design space for database schedules (ADMS 2014). With QTM, we generalize the modeling of parallel query execution such that different approaches become comparable. Additionally, I exploit the usage of GPUs for database algorithms and the interaction between compilers and databases.
