Applications programming

Applications programs are programs written to solve specific problems, to produce specific reports, or to update specific files. The term is used in contradistinction to systems programming, which  deals with the development of the software tools that the applications programmer uses. The programming languages that are used most often in applications programming languages that are used most often in applications programming are Fortan,  Ada,  and  C for scientific applications and Cobol for data processing applications. Special Report Program Generator (RPG) languages are used on small data processing computers, and languages like  Basic, Pascal, and APL were used extensively in early time-sharing systems.

The ultimate aim of all software is make it possible for the applications programmer to perform well and to write programs  that produce results and make effective and effective and efficient use of the computing system. Applications programs make use of subroutine libraries and special packages such as sort-merge systems and data access and database management systems. Most well-designed operating systems provide the applications programmer with special tools analyzing and debugging programs.

There are very large applications systems such as reservations systems and online banking and merchandising systems in which many considerations of systems programming and of applications programming are intermixed. Increasingly, such applications are programmed in an object-oriented language such as C++ or Java.
