Which feature in SAP HANA allows for the consolidation of data from various sources?

The feature that enables the consolidation of data from various sources in SAP HANA is data federation. This capability allows users to access and integrate data from disparate systems without moving it physically into the HANA environment, thereby providing a unified view of the data. Data federation works by creating virtual tables that represent data from external sources, making it possible for users to query this data alongside data stored within the HANA database itself.

The ability to connect to multiple data sources, such as different databases and applications, enhances analytics and reporting processes by providing a cohesive data framework. Users are able to execute complex queries that span across these various sources seamlessly, thus supporting real-time analytics and decision-making.

The other options serve different purposes. Data mirroring typically refers to replicating data within the same system for redundancy and high availability, which does not inherently consolidate diverse data sources. Data modeling focuses on designing the structure and relationships of data in the database to optimize performance and usability but does not itself integrate data from multiple external sources. Data virtualization allows for the abstraction of data access and integration but is not as commonly emphasized in the context of consolidation in SAP HANA, where data federation is the key feature for this purpose.
