SAP buffering
Takes data from database tables defined in ABAP Dictionary and buffers it 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 usually improves performance significantly (by factors of between 50 and 500) and is managed by the database interface. It is mostly applied to reads using Open SQL statements, but is bypassed by some variants.
