What is one key use of smart data access?

Smart Data Access (SDA) enables the integration of data from different sources without the need for physical data replication. This is significant because it allows for real-time access to data that resides in various external databases while maintaining the data in its original location. By using SDA, users can create virtual tables in SAP HANA that reference data from these external sources, which helps in reducing data duplication and storage costs, and also facilitates more efficient data management.

Leveraging SDA is particularly beneficial in scenarios where organizations wish to perform analytics on a diverse set of data sources while maintaining the integrity and freshness of the data. This capability allows HANA to seamlessly query and aggregate data from various databases as if it were part of its own in-memory environment, enhancing the overall analytical capabilities without the overhead associated with physical data movements.

Other choices involve aspects that are not core to the purpose of Smart Data Access, such as increasing processing power, configuring memory settings, or managing user roles, which are operational tasks rather than integration functionalities.
