Data Storage
ABAP programs generally work with data imported from persistent memory
media to the internal session of the current program execution. This
data is then available to the program as transient data. For performance
reasons, data can also be stored in the shared memory of the
current application server. This shared memory is available to all
programs of an application server. Access to data in the
shared
memory is faster than accessing data in persistent memory media by
some magnitude.
