10. © Swagelok Company, 2002 Application Interface is the Key Provides a precise, unambiguous, and universal definition of each attribute. Prioritizes the data exchange as either real-time data or non-time-critical. Insulates SAM from any data idiosyncrasies caused by variations in implementation. Facilitates interoperability of components regardless of communications architecture. Promotes refinement of system and featureware requirements. Small investment to adopt an existing technology.
