Column oriented databases
By searchguy on Sep 06, 2007
Interestingly, the approach taken by the "column stores" that he describes are characterized by:
- Column orientation
- Aggressive data compression
- Query executor runs against compressed data
These are, essentially, the three characteristics of an inverted file-based information retrieval system. The inverted file is the column orientation, and any recent IR text will point out that processing compressed postings is a lot faster than dealing with uncompressed data.
