| Kurzbeschreibung | Analytic DBMS für Hadoop | Weit verbreitetes, allgemein einsetzbares Open Source RDBMS  Entwickelt als objektorientiertes DBMS, im Laufe der Zeit um 'Standards' wie SQL erweitert | Open Source Operational and Transactional Enterprise NoSQL Document Database | A DBMS built for use on mobile devices that’s a fast, easy to use alternative to SQLite and Core Data | Popular in-memory data platform used as a cache, message broker, and database that can be deployed on-premises, across clouds, and hybrid environments Redis legt höchsten Wert auf Performanz. Bei Designentscheidungen wird typischerweise Performanz der Vorzug vor Features oder Speicherbedarf gegeben. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
