Column-Oriented Databases

Relational databases are being outperformed by databases that flip tables 90 degrees to store data vertically in table columns rather than in successive rows. By putting similar data together, column-oriented databases minimize the time to read the disk, which can add up when executing large-scale calculations such as those typically done in a data warehouse.
