| Kurzbeschreibung | Embeddable fast key-value storage library that provides an ordered mapping from string keys to string values | Scalable, distributed, serverless MySQL database platform built on top of Vitess | Weit verbreitetes, allgemein einsetzbares Open Source RDBMS  Entwickelt als objektorientiertes DBMS, im Laufe der Zeit um 'Standards' wie SQL erweitert | Distributed, high-performance timeseries database | 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. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Primäres Datenbankmodell | Key-Value Store | Relational DBMS | Relational DBMS mit objektorientierten Erweiterungen, z.B.: benutzerdefinierte Datentypen/Funktionen und Vererbung.
