Yup, hotel reservation isn’t much different than an airline reservation.

A hotel is just an airplane without wings :) zTPF is great for any high volume transaction where there are few transaction types but many per second (IBM claims million tps) and at low cost. The tradeoff is constrained application function, but not so bad now with zTPF support all the open interfaces such as REST. Think of it as a stripped down IMS or CICS, with much leaner application interface. Currently only C/C++, Java and assembler are supported as a programming language, and some things only in C/C++. zTPF has no LE malaise that z/OS is saddled with :) On Sat, Mar 20, 2021 at 12:00 PM Bill Johnson < 00000047540adefe-dmarc-requ...@listserv.ua.edu> wrote: > Been around for decades as the airline system but usable by any industry > requiring massive throughput. > > > Sent from Yahoo Mail for iPhone > > > On Friday, March 19, 2021, 8:16 PM, Radoslaw Skorupka < > r.skoru...@hotmail.com> wrote: > > Old only? > I have read about relatively new and small airlines, not mentioned below. > And of course airline control program is not really applicable to banks > and hotels.
