KurzbeschreibungA MySQL compatible DBMS with Git-like versioning of data and schemaFully managed big data interactive analytics platformScalable, ACID-compliant graph database designed with a high-performance distributed cluster architecture, available in self-hosted and cloud offeringsWeit verbreitetes, allgemein einsetzbares Open Source RDBMS infoEntwickelt als objektorientiertes DBMS, im Laufe der Zeit um 'Standards' wie SQL erweitert
Primäres DatenbankmodellRelational DBMSRelational DBMS infocolumn orientedGraph DBMSRelational DBMSRelational DBMS infomit objektorientierten Erweiterungen, z.B.: benutzerdefinierte Datentypen/Funktionen und Vererbung. Key/Value handling mit hstore Modul.
Sekundäre DatenbankmodelleDocument StoreDocument Store infoIf a column is of type dynamic docs.microsoft.com/­en-us/­azure/­kusto/­query/­scalar-data-types/­dynamic then it's possible to add arbitrary JSON documents in this cell
Event Store infothis is the general usage pattern at Microsoft. Billing, Logs, Telemetry events are stored in ADX and the state of an individual entity is defined by the arg_max(timestamps)
