What is one of the main advantages of using Column-based database technology in SAP HANA?

One of the main advantages of using column-based database technology in SAP HANA is faster data retrieval. In a columnar database architecture, data is stored in columns rather than rows. This format is particularly beneficial for analytical queries that often involve aggregating or filtering large volumes of data.

When data is organized by columns, the database can read just the necessary columns needed for a query, rather than scanning entire rows. This optimizes I/O operations and reduces the amount of data that needs to be read from disk, leading to significantly improved performance for analytical queries. This design is especially effective for scenarios where only a subset of attributes is needed, allowing for rapid access to the relevant data.

On the other hand, the other options do not capture the primary strength of column-based technology in SAP HANA. While it can support complex SQL operations, the main advantage highlighted is focused on retrieval speed due to its efficient design for analytical processing. Similarly, while there may be improvements in data writing speeds depending on context, it is not as universally recognized a benefit as the faster retrieval capabilities. Lastly, while better support for multi-dimensional data can be a factor in some scenarios, it is not inherently a primary advantage of the columnar storage itself. Thus, the choice reflecting
