What is IBMs System Application Architecture?
SAA is a collection of selected software interfaces, conventions, and protocols that are used as a framework for developing consistent, integrated applications across the major IBM computing environments. Four major components of this architecture are: • Common User Access (CUA) defines conventions for GUI look and feel. • Common Programming Interface (CPI) provides languages, tools, and APIs that give applications greater portability and more consistent user interfaces across multiple platforms. • Common Communication Support (CCS) supports existing communications standards, such as LU 6.2. • Common Applications, written by IBM, will serve as demonstrations of SAA concepts and make it easy for users to migrate between systems.
