Exadata is Oracle's database machine that combines database servers with intelligent storage servers. It uses several techniques like column projection, predicate filtering, and storage indexes to drastically reduce the amount of data that needs to be transferred from storage to the database servers. This allows Exadata to process queries much faster than a traditional database system.
