What are the features of SDA?

The feature related to the evaluation and execution of push down possibilities to remote sources is a fundamental component of Smart Data Access (SDA) in SAP HANA. SDA allows users to connect to and query data from remote databases without loading the data directly into the HANA system. This involves determining the best approach to execute queries on the remote data sources, which often involves pushing down the necessary processing to those sources. This capability enhances performance by reducing the data movement over the network and leveraging the computational power of the remote systems.

By maximizing the use of existing data sources and executing queries where the data resides, SDA significantly optimizes data access and analysis while maintaining real-time performance capabilities. This means that users can work with larger datasets effectively without overloading their HANA system, ensuring efficient data processing workflows.

Other features mentioned, such as merging data from multiple sources, automatic data type translation, and data cleansing, are important aspects of data management but do not specifically highlight the unique functionality of SDA as it pertains to the execution of operations directly on external databases. These capabilities may exist in a broader data integration context but do not encompass the core advantages that SDA provides in terms of remote source interaction and push down processing.
