Introduction to Communications for the AS/400-Second edition.
This book clarifies all the basic concepts you need to know to plan for effective communications solutions that work with your AS/400. The second edition has been revised to address the sweeping communications changes introduced with V3R1 of OS/400. As a result, An Introduction to Communications for the AS/400 now covers the broad range of AS/400 comunications topics including integrated digital networks, optical fibers used in LANs and WANs, public and private X.25 networks, client/server relations and products, heterogeneous networks and TCP/IP and much more includes an extensive glossary that serves as a communications primer.

Essentials of Subfile Programming
Today, programs and systems are increasingly screen-based and interactive. Subfiles are the AS/400 tool that lets you display lists of data on the screen for user interaction. Your knowledge of subfiles will increase your marketability and prepare you to move to the next level with confidence.
Essentials of Subfile Programming teaches you to design and program subfiles, offering step-by-step instructions and real-world programming exercises that build from chapter to chapter. You'll learn to design and create subfile records
load, clear, and display subfiles
develop display-file code and RPG code for interactive file maintenance
create pop-up windows for user interaction support users with advanced prompting features and Help screens
<*dv_2*> Advanced topics in RPG will help you
link RPG programs and database files, including using the record format level identifier and the OVRDBF (Override with Database File) and OPNQRYF (Open Query File) commands mine the rich store of data in the file-information and program-status data structures handle errors, including using the *PSSR subroutine, the INFSR keyword and LO indicators, error messages, and error logs improve data integrity by using journaling and commitment control manage program-to-program communications, especially via the power of AS/400 data queues

| "Data Warehousing and the AS/400
provides an outstanding guide to make data warehouse/data mart implementation into a huge success."
Shaku Atre, President, Atre, Inc.
"...excellent job of describing both the AS/400 facilities for data warehousing and the software solutions available on the AS/400... excellent guidelines for implementation and practical examples for integrating DB2/400, servers, and partner software to build your data warehousing applications quickly and correctly."
Van Symons, Business Intelligence Segment Executive, IBM Corporation, AS/400 Division Can you readily identify your most profitable customers?
Are your factories producing the optimal mix of products?
Should you increase inventory levels in particular stores or regions?
Can you identify trends in time to act upon them?
If you have to stop and think about the answers to these questions, or most of your answers are "No," then you need this book. The information required to effectively address these and other critical issues is probably already in your corporate database. However, without a data warehouse, you stand little chance of gaining timely access to it. Unlike traditional applications that process the daily workflow of an organization, data warehouses are designed specifically to support decision-making. The results? Better decisions are made in less time, which can lead to greater customer satisfaction and higher profits. In this book, Scott Steinacher takes an in-depth look at data-warehousing components, concepts, and terminology. After laying this foundation, Scott presents a compelling case for implementation on IBM's AS/400 midrange computer.
