Column-oriented DBMS
From Wikipedia, the free encyclopedia
A column-oriented DBMS is a database management system (DBMS) which stores its content by column rather than by row. This has advantages for read-mostly databases such as data warehouses and library catalogues.
Examples of column-oriented DBMSs include:
- Sybase IQ [1]
- KDB
- Addamark (now the Sensage event log analyzer[2])
- C-Store and its commercial version Vertica
- MonetDB open source, university project [3]
