Application of Database

“Application of Database”

Abstract

A database application is a computer program whose primary purpose is entering and retrieving information from a computer-managed database. Early examples of database applications were accounting systems and airline reservations systems, such as SABRE, developed starting in 1957. The etymology of the phrase "database application" comes from the practice of dividing computer software into systems programs, such as the operating system, compilers, the file system, and tools such as the database management system, and application programs, such as a payroll check processor. On a standard PC running Microsoft Windows, for example, the Windows operating system contains all of the systems programs while games, word processors, spread sheet programs, photo editing programs, etc. would be application programs. As "application" is short for "application program", "database application" is short for "database application program".
