Which of the following best describes the purpose of a view in SAP HANA?

The purpose of a view in SAP HANA is primarily to present data from one or more tables without storing it physically. A view acts as a virtual table that displays data only when queried. It allows users to see aggregated, filtered, or joined data based on the underlying tables, without duplicating storage by creating a physical copy of that data. This makes views efficient for data management and querying, as they can simplify complex queries and enhance productivity by allowing users to interact with data in a structured manner without the need for additional physical storage.

The other options do not accurately reflect the role of a view in SAP HANA. Creating physical tables is not a function of views, as they are entirely based on existing tables. Views also do not execute data backup procedures, which are handled by different mechanisms in the database. Similarly, while monitoring user activity is essential in database administration, it is not related to the functionality or purpose of views. Thus, the correct understanding of views reinforces their role in providing a flexible, dynamic interface to the data stored in the database.
