In the Second Edition of this Book
Many new subjects that reflect the latest AS/400 technologies have been added to the second edition. These new topics include:
  • Java on the AS/400
  • Client/Server with the AS/400
  • TCP/IP Network
  • Internet and Web with the AS/400
  • Internet Security and Firewall for AS/400
  • HTTP Server
  • Groupware, Lotus Notes, and Domino for AS/400
  • SAP on the AS/400
  • Using Client Access
  • AS/400e Series and e-business Solutions

The second edition is distinct in its breadth, completeness, depth, and ease of use. It engages readers in hands-on projects while using a combination of text, tutorials, and lab exercises. Detailed and step-by-step illustrations and instructions using graphics, screens, displays, tables, diagrams, and examples are employed throughout the book.

Chapters of this book are organized into six major parts:

System
The chapters in Part 1 (System) discuss the major characteristics of AS/400. It introduces the AS/400 system architecture and operating system. Tutorials and lab exercises are used to illustrate the AS/400 environment and to teach the use of AS/400 menus and various displays. AS/400 Control Language (CL), which is essential for performing various system and programming tasks, is introduced. The AS/400 work management structure and job processing are explained. Other topics include storage management, system security, backup and recovery, and object-oriented architecture and programming.

Utilities
The chapters in Part 2 (Utilities) use step-by-step instructions showing readers how to use the AS/400 utilities, commonly called programming development tools, to develop their applications. These tools include Source Entry Utility (SEU), Data File Utility (DFU), Screen Design Aid (SDA), and Programming Development Manager (PDM). In each of the chapters, tutorials, screen displays, and lab exercises are used to maximize the reader's learning experience.

Database
The chapters in Part 3 (Database) discuss the concept and structure of the relational database in general and the AS/400 database, DB2/400, in particular. It uses a combination of forms, examples, and lab exercises to explain to readers the use of Data Description Specifications (DDS) in defining the AS/400 database files.

Programming
The chapters in Part 4 (Programming) introduce AS/400 programming languages. The AS/400 Control Language Programming (CLP) is discussed through various examples. Tutorials are used to dissect other major programming languages, including RPG/400, COBOL/400, and SQL/400. ILE, the AS/400 new integrated language environment, is examined and explained. A comparative perspective between RPG/400 and its predecessor, RPG II, is presented. Query/400, an AS/400 utility, which allows users to retrieve data and create reports without the knowledge of a specific programming language, is taught through step-by-step instructions and and lab exercises. Finally, Java, the object-oriented and Web-enabled programming language that has received wide-spread attention lately, is discussed through a tutorial.

Client/Server, Networking, and Internet
The chapters in Part 5 (Client/Server, Networking, and Internet) discuss client/server, networking, and internet - perhaps the most explosive topics and movements in today's computer industry and the focal points of the AS/400 in recent years. Included in the Part 5 are: Client/Server with the AS/400, a tutorial for TCP/IP network, internet and Web with the AS/400, internet security and Firewall for AS/400, HTTP server, Groupware, Lotus Notes, and Domino for AS/400, SAP on the AS/400, and a tutorial for using Client Access.

Project
The chapter in Part 6 (Project) presents step-by-step instructions that guide readers through the development of an application project. It reconstructs and expands the procedures specified in lab exercises and lab assignments of the preceding chapters to create the Asset Master application project. The structured instructions in this section assist readers in learning to use the AS/400 database, utilities, query, and CL commands when coding and developing application and programming projects.

Tutorials, Lab Exercises, and Lab Assignments
The tutorials, lab exercises, and lab assignments in many of the chapters enable readers to develop application projects through hands-on activities using various AS/400 utilities, database, and programming languages. They include CL commands, DB2/400, DDS, SEU, PDM, DFU, SDA, Query/400, and RPG/400. After the completion of these exercises and assignments, readers will have completed two major application projects: the Asset Master and Employee Master.

Who Can Use This Book
This is a technical book written for both novices and experienced computer professionals. AS/400 users and students can use this book to learn the ins and outs of the system and to acquire the basic knowledge of the AS/400. Programmers, system analysts, system administrators, database administrators, and operators can use this book to learn application development, system administration, database design, programming, and operation of the AS/400. Both beginning and experienced computer professionals will benefit from the detailed hands-on tutorials, graphical screen illustrations, step-by-step instructions, and lab exercises. The structured tutorials and practical knowledge offered by this book make it ideal material for technical reference, self-study, and classroom teaching and learning.
