Storing a Bit smaller than in one Bit
When thinking about compression, one often thinks that a bit can not be compressed in less than a bit. In this article, I will prove otherwise. (mehr …)

On Compressing NULL values in bit-compressed Integer Storages
Usually, databases store NULL values in form of bitmasks. In this case, each value eats up 1 bit for the possibility to become NULL. I will prove that we can do better. (mehr …)
memcp: Eine OpenSource hochperformante Spaltenbasierte In-Memory-Datenbank als Alternative zu proprietären analytischen Datenbanken
