mask-of-zorro,
TPF = Transaction Processing Facility is a high-availability, high-performance system, designed to support real-time, transaction driven applications. The specialized architecture of TPF is intended to optimize system efficiency, reliability, and responsiveness for data
communication and database processing. TPF provides real-time inquiry and update to a large, centralized database, where message length is relatively short in both directions, and response time is generally less than three seconds. Formerly known as the Airline Control Program/Transaction Processing Facility (ACP/TPF).
Most TPF applications are written in assembler. They are very small and very fast. TPF programs track everything from reservations on millions of airline flights, advanced seat selection and on-time performance of aircraft. I wonder how well a network of distributed servers can handle what is essentially a huge inventory application with very perishable product?
