Translation of "Systems Application Architecture" into English

An IBM-developed standard for the appearance and operation of application software that will give programs written for all IBM computers--mainframe computers, minicomputers, and personal computers--a similar look and feel. SAA defines how an application interfaces with both the user and the supporting operating system. True SAA-compliant applications are compatible at the source level (before being compiled) with any SAA-compliant operating system--provided the system is capable of furnishing all the services required by the application.
