To run queries across tenant databases in a multitenant database container (MDC) system, you need to ensure that the user in the source system is associated with a user in the target database. This association, often known as a remote identity, is crucial because the associated user in the target database will execute the query and their authorization is checked. Additionally, cross-tenant database communication must be explicitly activated as it is not enabled by default and requires configuration.

The system usage types automatically assigned to tiles in the SAP HANA cockpit are Quality assurance, Development, and Production. These usage types are typically predefined and crucial for the management and monitoring of various environments within SAP HANA. Custom type is user-defined and not automatically assigned, and Test environments are often managed similarly to Quality Assurance.

Restricted users are initially limited in the ways they can interact with the database. Specifically, they cannot create objects or view data due to not being granted certain roles. By default, they are only allowed to connect via HTTP or HTTPS.

When you select the 'Do not compare table contents' option during the database migration option (DMO) procedure, the following actions are performed: The clustered tables are declustered, facilitating the transition to the new database structure. Additionally, a row count is executed for the migrated tables to ensure data accuracy in terms of the number of rows, without comparing the actual contents of the rows. Generating a check sum every 10000 rows or content comparison for repository tables would defeat the purpose of opting not to compare table contents.

A user group administrator can manage multiple user groups, and a user group can have multiple administrators. This means that there is not a strict one-to-one relationship between user group administrators and user groups.
