Databases
A (Relational) Database Management System of the following types:
- SAP HANA
- SAP ASE (also referred to as SAP Sybase ASE)
- SAP IQ
- SAP SQL Anywhere
- SAP MaxDB (also referred to as SAP DB)
- Microsoft SQL Server (also referred to as MSSQL server)
- IBM DB2
- Oracle
- PostgreSQL
- MySQL and MariaDB
This can either be a standalone Database or a database instance of an SAP System‚ or a liveCache, etc.
A Database is hosted by exactly one Physical Server or Virtual Cluster Server, but multiple Databases can be hosted on the same server.
If you want to manage or monitor a Database, you need to manage or monitor the Physical Server or the Virtual Cluster Server the Database is hosted on.
From a license perspective, it depends if a Database is the primary Database of an SAP System or not. If yes, the license is included in the SAP System's license. If not, a separate Database license is required. The only exception is the System DB of an SAP HANA database which does not consume a license.
