Proximity and MonetDB

"PROXIMITY incorporates major research findings from the Knowledge Discovery Laboratory, including model corrections for statistical biases inherent in relational data such as autocorrelation and degree disparity, as well as our graphical query language. PROXIMITY provides an open-source platform that can be used for both research into relational knowledge discovery and practical applications to real-world data."

"MonetDB achieves this goal using innovations at all layers of a DBMS: a storage model based on vertical fragmentation, a modern CPU-tuned vectorized query execution architecture that often gives MonetDB a more than 10-fold raw speed advantage on the same algorithm over a typical interpreter-based RDBMS. MonetDB is one of the first database systems to focus its query optimization effort on exploiting CPU caches. MonetDB also features automatic and self-tuning indexes, run-time query optimization, a modular software architecture, etc.. In-depth information on the technical innovations in the design and implementation of MonetDB can be found in our digital library."
