Summary

Regardless of whether an Internet commerce system is small or large, transaction processing principles cannot be ignored. Even a very simple commerce application consisting of a Web-based order form that appends orders to a file must carefully use file-locking techniques to ensure that nearly simultaneous orders do not cause lost orders or scramble the file. A medium-sized commerce application might use a database management system incorporating transactions, and a very large application might use a TP monitor to route Internet orders into an existing order processing system.
