Column Stores
Column-oriented Databases (CoDbs):
- are based on the relational model
- store data column-by-column rather that row-by-row
- leading to performance gains for analytical applications
Ideas for CoDbs have been around since the 1970's
Rose to prominence via Daniel Abadi's PhD thesis (MIT, 2008)
Commercial systems have now been developed (e.g. Vertica)
