What is a primary feature of calculation views in SAP HANA?

Calculation views in SAP HANA are primarily used for data modeling. They represent a powerful way to define complex calculations, aggregations, and data manipulations that allow users to analyze and process data effectively. With calculation views, developers can create reusable models that combine data from various sources, making them integral for building analytical applications and reports.

The feature of data modeling encompasses defining various structures like graphical or SQL-based models, using both calculated columns and measures, and embedding advanced analytical capabilities directly within the model. This facilitates the preparation and optimization of data for analytical purposes, allowing for a flexible and dynamic approach to data consumption.

In contrast, data encryption, data visualization, and data extraction serve different purposes. Data encryption focuses on securing data, ensuring its confidentiality, while data visualization pertains to how data is represented graphically, often using front-end tools for reporting. Data extraction refers to the process of retrieving data from various sources, which is not the primary function of calculation views in HANA.
