Question

The SAP HANA database relies on which of the following technologies for storing data?There are three correct answers

1) In-memory
2) Aggregation
3) Indexing
4) Columnar store
5) Compression

Answer 1

The SAP HANA database relies on In-memory technology, Columnar store, and Compression for storing data. Aggregation and Indexing are data processing operations, not storage technologies.The correct answer is option A.

Step-by-step explanation:

The SAP HANA database utilizes various technologies for data storage and processing, with emphasis on performance and efficiency. Among the listed options, three features correctly describe the core technologies used by SAP HANA:

• In-memory technology, which stores data directly in the RAM, significantly speeding up data access as opposed to retrieving it from traditional disk storage.
• Columnar store is a method where data is stored in columns rather than rows, which improves the performance of read-intensive operations and allows for better data compression rates.
• Compression is a technology applied in SAP HANA to reduce the size of the data stored in memory, allowing for efficient use of space and increased processing speed due to less data being read from memory.

Aggregation and Indexing are also used in the SAP HANA database but they are not storage technologies, rather they are data processing operations. Aggregation refers to the summarization of data, and indexing is a way of organizing data to speed up query times.The correct answer is option A.
