Hi,

Single tenet system uses common data set as a global data set to access the data entire holding company level.

Example: accenture uses hcm application for maintaining their internal employees. Here we use single tenet.

Example: ADP uses multi tenet system for their clients( EMC2 and EY). Here EMC2 and EY enterprises are different and cannot use common data set here.

So we will use enterprise data set to restrict access only for that company enterprise level.
