ABAP (Advanced Business Application Programming)

Si WIKI mau bicara dulu perihal ABAP, bahasa pemrograman yang ada di dalam Sistem SAP.

ABAP (Advanced Business Applications Programming, originally Allgemeiner Berichts-Aufbereitungs-Prozessor, German for "general report creation processor") is a high-level programming language created by the German software company SAP. The syntax of ABAP is somewhat similar to COBOL.

ABAP is one of the many application-specific fourth-generation languages (4GLs) first developed in the 1980s. It was originally the report language for SAP R/2, a platform that enabled large corporations to build mainframe business applications for material management and financial and management accounting.

ABAP was one of the first languages to include the concept of Logical Databases (LDBs), which provides a high level of abstraction from the basic database level(s).

The ABAP languange was originally used by developers to develop the SAP R/3 paltform. It was also intended to be used by SAP customers to enhance SAP applications - customers can develop custom reports and interfaces with ABAP programming.

The language is fairly easy to learn for programmers but it is not a tool for direct use by non-programmers. Knowledge of relational database design and preferably also of object-oriented concepts is necessary to create ABAP programs.

ABAP remains as the language for creating programs for the client-server R/3 system, which SAP first released in 1992. As computer hardware evolved through the 1990s, more and more of SAP's applications and systems were written in ABAP. By 2001, all but the most basic functions were written in ABAP. In 1999, SAP released an object-oriented extension to ABAP called ABAP Objects, along with R/3 release 4.6.

SAP R/3

Berikut petikan kalimat dari Si WIKI perihal SAP R/3.

SAP R/3 is the former name of the enterprise resource planning software produced by SAP AG. It is an enterprise-wide information system designed to coordinate all the resources, information, and activities needed to complete business processes such as order fulfillment or billing.

The first version of SAP's flagship enterprise software was a financial accounting system named R/1 called as NTR. This was replaced by R/2 at the end of the 1970's.

SAP R/2 was in a mainframe based business application software suite that was very successful in the 1980s and early 1990s. It was particularly popular with large multinational european companies who required soft-real-time business applications, with multi-currency and multi-language capabilities built in.

With the advent of distributed client-server computing SAP AG brought out a client-server version of the software called SAP R/3 (The "R" was for "Real-time data processing" and 3 was for 3-tier). This new architecture is compatible with multiple platforms and operating systems, such as Microsoft Windows or UNIX. This opened up SAP to a whole new customer base.
