Supported databases

Review the supported database types and versions to ensure that you are using one that is supported.

Only supported database types and versions can be used as external databases.

If you would like to use an external database for one of the components that support it, you may use the database types and versions defined in the Support Matrix.
For more information on whether a default database is provided by default and for steps for configuring an external database, refer to the component-specific documentation:
