In 1972, five systems analysts began working nights and weekends to create standard software with realtime data processing. Twenty-five years later their vision is a reality: SAP is the world’s market and technology leader in business application software.
On April 1, 1972 five former IBM employees founded SAP as Systemanalyse und Programmentwicklung (“Systems Analysis and Program Development”) in Mannheim, Germany. Their vision was to develop and market standard enterprise software which would integrate all business processes. The idea came to them through their work as systems consultants for IBM when they noticed that client after client was developing the same, or very similar, computer programs. The second part of their vision was that data should be processed interactively in realtime, and the computer screen should become the focal point of data processing...
ABAP (Advanced Business Application Programming) is a high level programming language created by the German software company SAP. It is currently positioned, alongside the more recently introduced Java, as the language for programming SAP's Web Application Server, part of its NetWeaver platform for building business applications. Its syntax is somewhat similar to COBOL.
History
ABAP originated from an assembler macro language for reporting purposes in the seventies.ABAP evolved to an interpreted language for reporting and dialog programming in the mid-eighties, with compiler and VM implemented in mainframe assembler as part of the SAP R/2 system.In the early and mid-nineties it was known as ABAP/4 and it became the programming language for all SAP R/3 applications with the compiler and VM implemented in C as part of the SAP R/3 kernel.
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 materials management and financial and management accounting. ABAP used to be an abbreviation of Allgemeiner Berichtsaufbereitungsprozessor, the German meaning of "generic report preparation processor", but was later renamed to Advanced Business Application Programming. 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.
The ABAP programming language was originally used by developers to develop the SAP R/3 platform. 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. Good programming skills, including knowledge of relational database design and preferably also of object-oriented concepts, are required to create ABAP programs.
ABAP remains 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.
