Table buffering is used to increase performance when reading data from database table. Data from a buffered table is read from a local buffer on the application server thus reducing database access.

There are three different types of table buffering that can be used in SAP:

Full Buffering : All Records of the table are loaded into the buffer when a record in the table is accessed.
Generic Buffering: All Records with the same key fields are loaded into the buffer when a record in the table is accessed.
Single Record Buffering: The specific record that was accessed is loaded into the buffer.
