SAA (Systems Application Architecture)
Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.
SAA is a set of application, communication, and user-interface specifications for IBM mainframe operating systems such as VM (Virtual Memory) and MVS (Multiple Virtual Memory), midrange operating systems like OS/400 (for IBM AS/400 series), and OS/2 for desktop systems. SAA defined common applications, which are applications that can run on any SAA platform. Thus, applications written to SAA can run on a wider range of systems. SAA was an attempt by IBM in the 1980s to provide compatibility among its mainframe and minicomputers, which had previously been developed by different IBM divisions.
