A fourth generation ProgrammingLanguage developed by SapCorporation (SAP AG).
ABAP/4 stands for Advanced Business Application Programming. It is the programming language that SAP AG has used to develop all of the SAP R/3 business modules, applications, and system management functions. The current incarnation is called AbapObjects.
ABAP... "German COBOL". ABAP is a very cumbersome language and SAP R3 is a cumbersome development environment.
Q Is AbapLanguage going to play any significant role in NetWeaver?
A Yes. NetWeaver will contain two language stacks: Java (actually, J2EE), and ABAP Objects. The vast majority of the SAP business coding is and will remain for quite some time written in ABAP.
