CWI PhD graduate founded record IPO company Snowflake

Data-warehouse company Snowflake went public this week, reaching an extraordinary market value of $70.4 billion, the largest IPO for a software company ever. Snowflake offers cloud-based data warehousing, whose data storage and query engine contain techniques pioneered in CWI’s Data Architectures group. One of the PhD graduates who developed that technology, former CWI researcher Marcin Żukowski, is co-founder of Snowflake.

Integrating data science and relational systems

Data scientists have largely overlooked relational database systems, even though these could greatly help their research. The systems did not gain traction, because combining them with databases proved to be slow and cumbersome. Now CWI researcher Mark Raasveldt bridges that gap. In his thesis, he proposes several novel techniques that make database management systems easier to use and more efficient.

CWI & Databricks: Big Data in Amsterdam

Amsterdam wants to play a leading international role in the development of data science research. In Big Data Amsterdam, Financieele Dagblad journalist Job Woudt interviews Amsterdam Data Science researchers on the functioning of the ecosystem where companies and knowledge institutions in Amsterdam collaborate in the area of ​​Big Data.

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.

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.

Tracing Stars with MonetDB in the Cloud

The Dutch database technology company MonetDB Solutions and CWI will develop new techniques to facilitate the storage and analysis of the vast data volumes from the Square Kilometre Array (SKA) telescope. The project will be funded by a grant in the AstroCompute in the Cloud program of the SKA Organization (SKAO) and Amazon Web Services (AWS).
