Here is the first guide to this long-awaited, new generation of mid-size IBM computers. It provides everything needed to integrate each AS 400 system into small- medium-, and large-size business environments. There is detailed coverage of the basics - hardware, architecture, storage management, and a performance overview. Jim Hoskins explains how to integrate AS/400 with existing systems, from Personal System/2 to IBM's largest S/370 computers, and discusses key planning issues such as security, lease vs purchase, software compatibility and migration from the 3X systems. The book also covers advanced business systems - choosing the right software, advanced system hardware, training and more. The text will be of interest to management information services managers and business owners.
