Description
Leader of the group Database Architectures: Stefan Manegold.
We, the Database Architectures (DA) research group of CWI, are well known as a top data systems research group, active in the broad area of data (management) systems and infrastructure for supporting data science. Our research group has a strong international reputation in academia and industry for pioneering column store technology, fast compression methods, vectorized query execution, on-line query-driven indexing (cracking), adaptive caching, and integration of statistical languages and analysis in database management systems.
We develop, distribute and maintain the MonetDB open-source system, and we have spawned multiple spin-off companies, including Data Distilleries, VectorWise and MonetDB Solutions. Our team also operates a self-built cluster, SciLens, that – unlike many other computer clusters – is bandwidth-optimized and thus better suited as a data-science infrastructure. We pride ourselves on revealing the real problems in our discipline and coming up with revolutionary solutions that are frequently ahead of their time.
Vacancies
PhD Students in the areas of Big Data Management and Analysis Architectures and Data Science Engineering Technologies
Three fully funded PhD positions are available to work under the direction of prof. Stefan Manegold on big data management technology with a particular focus on hardware-conscious data structures and algorithms in distributed and cloud environments as well as the integration of data mining and machine learning into large-scale data management systems.
News
CWI develops new tools for data exploration
PhD student Thibault Sellam from CWI developed new tools to explore large databases. It allows explorative users to find interesting information hidden inside a database, with little or no knowledge of the data beforehand.
Martin Kersten receives 2016 SIGMOD Systems Award
Martin Kersten is the recipient of the 2016 SIGMOD Systems Award for the design and implementation of MonetDB, a pioneering main-memory database system based on a columnar data organization.
CWI spin-off MonetDB Solutions helps building ExaNeSt platform
In a new EU project MonetDB Solutions helps to showcase the future generation ExaNeSt platform, which consists of up to 10 million of low-cost and low-energy ARM processors. The CWI spin-off will evaluate the platform with extremely compute-intensive big data analytics applications.
Efficient method to make changes in compressed database
PhD student Sándór Héman from CWI developed a new method to compress a large database, allowing for a much faster transport of data from storage to processor. Furthermore he developed efficient algorithms to make changes within such a compressed storage layout.

CALL FOR PAPERS
1st International Conference on Big Scientific Data Management (BigSDM2018)
http://bigsdm2018.csdata.org
Nov. 30 - Dec. 1, 2018, Beijing, China
Submission Deadline: September 15th, 2018 (Abstract)
==================================================
The 1st International Conference on Big Scientific Data Management (BigSDM 2018) will be held in Beijing, China from Nov. 30th to Dec 1st, 2018. The Conference is jointly organized by Chinese Academy of Sciences, Peking University, Tsinghua University, Renmin University of China, CWI and MonetDB Solutions.
The theme of BigSDM 2018 is data-driven scientific discovery. The conference aims at bring together international experts from natural and computer sciences to explore the life-cycle management of Big Scientific Data, to discuss major methodologies and key technologies in Big Data-driven discovery making, to exchange experience and knowledge about Big Scientific Data across various fields through specific cases, and to identify the challenges and opportunities in scientific discovery acceleration. We hope to, through the conference, gather ideas for fostering new ways of scientific thinking, and promote big data sciences at large.
The program of BigSDM 2018 features several keynote talks by famous experts in the important areas of big data sciences. We have invited Barry C. Barish, the winner of 2017 Nobel Prize in Physics, Huadong Guo who is an Academician of Chinese Academy of Sciences, and Alexander S. Szalay, the bloomberg distinguished professor from the Johns Hopkins University to share their cutting edge technology and views about the big scientific data management. In the meantime, we are about to invite the principal researchers from major scientific experiments, such as the Five- hundred-meter Aperture Spherical radio Telescope (FAST), and major data projects, such as 'CASEarth' in China to share their experiences in data-driven scientific discovery. 'CASEarth' is a CAS Strategic Pioneering Research and Development Programme, focusing on building a global big data network to study Earth and support research on climate change, as well as to predict and mitigate natural disasters. The other events include topic-specific forums and lightning talks.
BigSDM 2018 welcomes researchers, professionals, practitioners, and officers worldwide in related areas to submit papers and attend the conference.
