In SAP HANA, which of the following describes the purpose of a calculation view?

The purpose of a calculation view in SAP HANA is to aggregate data from various tables for analysis. Calculation views are used to create complex queries by combining data from different database tables and sources, allowing users to perform advanced analytics and reporting. They can transform and manipulate data, enabling businesses to generate insights and make data-driven decisions.

By using calculation views, database administrators can model the data in a way that suits analytical needs, providing a layer of abstraction that allows for advanced calculations, aggregations, and business logic to be applied to data before it is accessed by users or applications. This flexibility makes them essential tools for implementing complex analytics in a HANA database environment.

The other choices do not accurately describe the primary function of calculation views in SAP HANA, as user access permissions, connecting to external data sources, and indexing relate to different aspects of database management and performance optimization rather than the direct purpose of calculation views.
