What transaction type does SAP HANA primarily support for data modification?

The primary transaction type that SAP HANA supports for data modification is DML, or Data Manipulation Language transactions. DML consists of commands that allow users to insert, update, delete, and manipulate data within the database. This includes operations like adding new records, changing existing records, and deleting records from tables.

In the context of SAP HANA, which is designed for real-time analytics and processing large volumes of data efficiently, the ability to execute DML transactions swiftly is critical. The high-performance capabilities of SAP HANA are optimized for executing DML operations, making it suitable for applications that require immediate data interactions, such as ERP systems, data warehousing, and other business applications.

Conversely, DDL (Data Definition Language) deals with the structure of the database, such as creating and modifying schema objects like tables and indexes. DQL (Data Query Language) is primarily focused on querying data (for instance, with SELECT statements) and does not involve modifying records. Lastly, while DRL could be considered synonymous with DQL in some contexts, it generally refers to retrieving data rather than modifying it. Thus, when it comes to altering the data itself, DML transactions are the key to achieving this in SAP HANA.
