What functionality does the SAP HANA Smart Data Access provide?

SAP HANA Smart Data Access (SDA) is designed to facilitate access to external data sources without the need for data replication. This allows users to query and work with data stored in different systems—such as SQL databases, NoSQL databases, and other data sources—directly from within SAP HANA. The critical advantage of SDA is that it enables real-time access to the external data while maintaining the integrity and security of the data source, as well as reducing the data movement across systems.

By using SDA, organizations can leverage data from various platforms in their analytics and reporting processes without the overhead associated with loading, transforming, and synchronizing massive data sets. This functionality is particularly beneficial for businesses that require up-to-date information and want to minimize storage costs and data management complexity.

Other choices presented involve functionalities that are distinct from what SDA offers. For example, data archiving typically involves the long-term storage of data to optimize system performance, while real-time data replication pertains to continuously synchronizing data between systems, which would involve transferring and updating data—contrary to the no replication aspect of SDA. Data transformation during load is related to processes where data is modified or structured as it is being loaded into a database, which is also outside the scope of
