HyPer: one DBMS for all – High-Performance OLTP AND OLAP on Brawny Servers AND Wimpy Devices


Ever increasing main memory capacities and processors with multiple cores have fostered the development of database systems that process and store data solely in main memory. This talk presents HyPer, a high-performance hybrid OLTP&OLAP main memory database system we are building at TUM. Unlike other main memory database systems, HyPer aims at providing highest performance for both, OLTP AND OLAP workloads on brawny AND wimpy systems. OLAP query processing is separated from mission-critical OLTP transaction processing using an efficient virtual memory (VM) snapshotting mechanism. Platform-independent high-performance OLTP and OLAP is achieved by efficiently compiling transactions and queries into efficient target machine code. Even though the SQL-92 standard, a PL/SQL-like scripting language, and ACID-compliant transactions are supported, HyPer has a memory footprint of just a few megabytes. This talk highlights the following recent research efforts in the HyPer project: Snapshotting a transactional database, indexing, parallel multi-core query evaluation, multi-version concurrency control.

This is joint work with my colleague Prof. Thomas Neumann and the HyPer team: www.hyper-db.de.


Alfons Kemper's research field is database systems engineering. He explores ways to optimize information systems for operational and scientific applications as a way to combat the data explosion. His main areas of interest are optimization concepts for distributed information structures, data integration methods and, in particular, main memory-based database systems. Together with his colleague Thomas Neumann he leads the HyPer main-memory database project (hyper-db.com) at Technische Universität München. HyPer is one of the first hybrid database systems that offers high-performance OLTP as well as OLAP in parallel on the same database state.

After studying computer science at the University of Dortmund from 1977 to 1980, he moved to the University of Southern California, Los Angeles. While there, he obtained his Master of Science and doctorate. Upon his return to Germany, he completed his lecturer qualification at the University of Karlsruhe. His first professorship was conferred by RWTH Aachen. After many years as Director of the Chair of Database Systems at the University of Passau, TUM offered him a position in 2004. From 2006 to 2010, he was Dean of the Department of Informatics at TUM. His textbook on database systems, published by deGruyter and now in its 10th edition, is a best-seller in German-speaking countries and is used in most universities and colleges.

As CTO of the first Cloud Computing initiative in IBM’s Corporate Strategy team he created the Beta for IBM’s first public cloud. As CTO of IBM Software Group he directed its technical and software engineering strategy, including the transformation to lean and agile development throughout the company. As head of development for Tivoli, he introduced service management concepts into its portfolio. As CTO for WebSphere he developed the technical strategy for the evolution of IBM’s application integration middleware platform in support of service-oriented architectures. As Director of the Hursley Lab in the UK and VP of Business Integration Development, he grew IBM’s message oriented middleware to a full integration portfolio including IBM’s first Enterprise Service Bus. As Director of the German Software Lab, he developed IBM’s first workflow management system.

He joined IBM in 1984 as a development engineer in the Boeblingen Development Laboratory in Germany, working on porting UNIX to the mainframe.

Dr. Kloeckner received a Master’s Degree and Ph.D. in Mathematics from Goethe University in Frankfurt, Germany and an honorary degree of Doctor of Science from the University of Southampton, UK. He is a Fellow of the BCS and since 1997 an honorary professor at the University of Stuttgart.

Algorithmic Problems in E-Mobility (with Solutions!)


Im Gegensatz zu gewöhnlichen Kraftfahrzeugen haben Elektrofahrzeuge heutzutage immer noch eine stark eingeschränkte Reichweite. Auf der anderen Seite sind sie in der Lage, während Bremsvorgängen oder bergab Energie zurückzugewinnen. Dies motiviert neue Fragenstellungen im Bereich der Routenplanung, welche wir im Vortrag näher untersuchen. Im selben Kontext stellen wir Optimierungsverfahren vor, welche gute Platzierungen entsprechender Aufladestationen berechnen. Schließlich betrachten wir das Problem der Selbstlokalisierung ohne GPS im Straßennetzwerk.


Stefan Funke is a Full Professor of Computer Science at the University of Stuttgart. From 2007 to 2010 he has been a Full Professor of Computer Science at the University of Greifswald, from 2005 to 2007 he was head of the Research Group Geometry-guided Design and Analysis of Wireless Sensor Networks within the Max-Planck-Center for Visual Computing and Communication, and from 2004-2005 he has been a Visiting Assistant Professor in the CS Department at Stanford University.

In 2002 he was awarded the Otto-Hahn-Medal by the Max-Planck-Society. In 2007 he received the Heinz-Billing Award together with Hannah Bast, and in 2008 he received the SaarLB Wissenschaftspreis again together with Hannah Bast.

Stefan Funke obtained a PhD and a Diploma in Computer Science the University of the Saarland in 1998 and 2001, respectively.

Industry 4.0


Der Begriff „Industrie 4.0" ist eine der erfolgreichsten Wortschöpfungen der letzten Jahre im Umfeld des produzierenden Gewerbes.  Selbst in Japan spricht man ohne Übersetzungsversuche von „Industrie 4.0". Große produzierende Unternehmen haben ihre eigene Industrie 4.0-Strategie, mittelständische und kleine Unternehmen kennen zumindest den Begriff und suchen nach ihrem Weg der Umsetzung. Erfunden wurde der Begriff jedoch  von einem Informatiker,
denn es geht im Kern um eine Digitalisierung der Produktion, also auch um einen Brückenschlag zwischen so unterschiedlichen Disziplinen wie Maschinenbau, Produktionsmanagement, Logistik und Informatik.  Der Vortrag führt in die Welt von Industrie 4.0 ein, beleuchtet das Thema aus Sicht eines Informatikers und stellt aktuelle Herausforderungen vor.


Dr. Harald Schöning holds a diploma and a PhD in Computer Science from the University of Kaiserslautern, Germany. For more than twenty years, he has been working for Software AG, in various roles including developer, project lead, and chief architect, and in various areas, from databases over semantic technologies, to SOA and business process management and beyond. Today he is Vice President Research at Software AG. He is chairman of the German Software Cluster, chairman of the German education initiative Software Campus, member of the board of NESSI (Networked European Software and Services Initiative) and the Big Data Value Association BDVA and has served as expert and reviewer for the European Commission and German ministries in several
contexts. Dr. Schöning has authored and co-authored several text books and many technical papers. He is inventor and co-inventor of more than 40 patents.

Next-Generation Hardware for Big Data Management – more a Blessing than a Curse?


Recent hardware developments have touched almost all components of a computing system: the existence of many and potentially heterogeneous cores, the availability of volatile and non-volatile main memories with an ever growing capacity, and the emergence of economically affordable, high-speed/low-latency interconnects are only a few prominent examples. Every single development as well as their combination has a massive impact on the design of modern computing systems especially in the context of Big Data. However, it is still an open question, if, how, and at which level of detail, a database system has to explicitly be aware of those developments and exploit them using specifically designed algorithms and data structures. Within the lecture talk I will try to give an answer to this question and argue for a clear roadmap of HW/SW-DB-CoDesign especially providing an outlook to upcoming technologies and discussion of their non-functional properties like energy-efficiency and resilience behavior.


Wolfgang Lehner is full professor and head of the database technology group at the TU Dresden, Germany. His research is dedicated to database system architecture specifically looking at crosscutting aspects from algorithms down to hardware-related aspects in main-memory centric settings. He is part of TU Dresden's excellence cluster with research topics in energy-aware computing, resilient data structures on unreliable hardware, and orchestration of heterogeneous systems; he is also a principal investigator of Germany's national "Competence Center for Scalable Data Services and Solutions" (ScaDS);

Wolfgang also maintains a close research relationship with the SAP HANA development team. He serves the community in many PCs, is an elected member of the VLDB Endowment, serves on the review board of the German Research Foundation (DFG), and is an appointed member of the Academy of Europe.
