Which function does the SAP HANA Smart Data Access (SDA) feature provide?

The function of SAP HANA Smart Data Access (SDA) is to allow users to access remote data sources as if they were local. This capability is crucial in scenarios where organizations want to utilize data from various systems without needing to physically move it into HANA. Through SDA, users can query and analyze data residing in different databases, cloud services, or even other SAP systems seamlessly; it integrates remote data sources into the HANA environment, providing the convenience of local data processing.

This means that analysts and data scientists can run queries against these remote datasets directly, leveraging HANA's in-memory computing power while maintaining the data's original storage location. SDA optimizes performance and flexibility, allowing for real-time data analysis and decision-making across distributed environments.

The other options reflect functionalities that are either too narrow or do not accurately represent the comprehensive capabilities offered by Smart Data Access. For example, data transformation and data import are aspects of data handling but do not capture the core function of SDA, which centers around enabling access to and querying of remote data.
