Data Processing R/3 system, a widely used business application
subsystem.
SAP will run using the previous version of ABAP, ABAP/4, or the newest: ABAP Objects. ABAP Objects is
object-oriented and the previous versions were created before object-oriented programming became
wide-spread. "ABAP Objects uses a single
inheritance model and full support for object features such as
encapsulation,
polymorphism, and persistence"
