Which characteristic describes a calculation view in SAP HANA?

A calculation view in SAP HANA is known for its ability to combine different data models, making it a versatile tool in data modeling. This characteristic is fundamental because calculation views can pull in data from various sources, including other calculation views, tables, and attributes, thereby allowing users to create complex data models that can support a wide range of analytical needs.

This flexibility plays a crucial role in scenarios where business intelligence applications require a unified view of data from disparate systems. By integrating various data sources and models, calculation views enable advanced analytics and reporting capabilities, which are essential for decision-making processes.

The other characteristics such as primarily storing data, only aggregating data, or being used solely for reporting purposes do not accurately represent the full functionality and purpose of calculation views. While they can involve aggregating data and can be used in reporting, their primary defining characteristic is the ability to integrate and model data from multiple sources effectively.
