How is database storage handled by SAP Master Data Governance (MDG) using reuse mode?

In SAP Master Data Governance (MDG) when using reuse mode, active data sets are managed in a way that optimizes database storage and ensures efficient data processing. Specifically, the correct choice reflects a key concept of the reuse mode: after activation, active data sets are indeed removed from the staging area.

This approach helps maintain a clean and efficient staging area that is reserved for data that has yet to be activated. By removing active data sets, the system minimizes the amount of unnecessary data stored in the staging area, leading to improved performance and easier management of master data.

The other options pertain to different aspects of data handling in MDG. For instance, the structure mapping and duplication concerns do not accurately represent the behavior of the reuse mode. In this mode, the focus is on integrating and activating data rather than maintaining duplicates or largely populated staging areas after activation. Effectively, the correct understanding of active set management is crucial for grasping how MDG optimizes data storage and keeps processes streamlined.
