Actian Vector, formerly Vectorwise, is a column-oriented DBMS which developed out of the CWI DA group's research in the 2000s, to create a query execution kernel optimized to achieve more instructions-per-cycle and to better utilize CPU cache.
WRITEME: Talk about how this project developed, more concrete initial goals and achieved goals, refer to processing chunks of a column (a.k.a. vectors) rather than the whole column, refer to VectorWise's website, mention other architectural featores like compressed storage and work on the compressed form etc.
