Which of the following is NOT a type of table buffering available?

The correct answer indicates that "Multi-key" is not a recognized type of table buffering in the context of SAP databases.

Buffering in SAP provides a mechanism to enhance performance by reducing database access for certain types of data. The types of table buffering that are indeed available include:

• Single-record buffering, which allows only individual records to be retrieved from the buffer, making it appropriate for scenarios where specific records are accessed frequently.

• Full buffering, where an entire table is loaded into memory. This is useful for small tables that are frequently accessed, allowing quick retrieval of any data from those tables without hitting the database each time.

• Primary-key buffering refers to buffering mechanisms that rely on the primary key to retrieve records efficiently, ensuring that access is optimized based on the unique identifiers of the data.

The absence of "Multi-key" among these recognized types highlights that it is not a standard buffering option within SAP, as buffering strategies typically focus on the aforementioned established types based on the methods of data access that are supported by the system.
