“By 2023, 75% of all databases will be on a cloud platform —
a development that will drastically change the DBMS vendor landscape.”
Gartner Defines - The operational database management system
(OPDBMS) market has been defined by relational and nonrelational DBMS products
suitable for the traditional transactions used to support business process
applications, both purchased (such as ERP and CRM applications) and
custom-made. Also includes DBMS products that support interactions and event
processing (data in motion).
Microsoft (Azure SQL, SQLDW, Cosmos...), Oracle,
AWS (DynamoDB, ElastiCache, Neptune, Timestream, RDS, Redshift &
EMR), Google (Cloud Spanner RDBMS, Cloud Bigtable, Cloud
Firestore...), SAP (SAP SQL, HANA...) and InterSystems are
the leaders in "Magic Quadrant for Operational Database Management Systems
2019".
