SAP buffering
Buffering of data from database tables defined in a table buffer in the shared memory of the current application server. The definition determines whether and how a database table is buffered. Buffering generally leads to greatly enhanced performance (by a factor of between 50 and 500) and is administrated by the database interface. Buffering usually becomes effective when Open SQL commands are used for database access. However, some variants do not use the buffering process.
