1.5 SAP Architecture
an SAP R/3 system is architecturally implemented as a layered model. There are
two main layers:
•Basis
• Application
The basis layer contains the R/3 system middleware. It is this middleware layer
that makes applications independent of the hardware platform, including the
operating system, database system, and the communication protocol that will be
used.
