As 400 Client Server Systems

Here's an invaluable hands-on guide to developing client/server applications on IBM's AS/400 version 3. This comprehensive reference details client/server concepts and techniques for the AS/400 and PCs featuring the latest AS/400 version 3. It features dozens of concrete examples of AS/400 client/server applications for the real world and real code examples with a business application emphasis.

Networking/AS/400 Timely, effective security for the AS/400(r) It may be hard to believe, but the AS/400 is not tamperproof, despite IBM's design efforts to that end. Consequently, the growing popularity of this system as a server means a greater security risk for everyone who uses it. AS/400 Security in a Client/Server Environment shows how to mount the strongest possible defense against security breaks in the AS/400, and how to recover quickly when they do occur. This readable, user-friendly book cuts through many commonly held misconceptions about security in general, and the AS/400 in particular. Through examples and case studies that read like detective stories, this book explains why the AS/400 represents such a tempting target to hackers, how bugs and viruses can be inserted into the system, and what preventive methods and techniques can fight them. This book provides the tools for bolstering the security of the AS/400 without restricting the normal functioning of the organization that is using it, including: Pointers on how to plan ahead for security problems when using the AS/400 as a server A 31 2" diskette containing security auditing and antivirus programs that clean up AS/400 bugs and viruses Figures and tables that illustrate the connection between design and potential threat Easily adaptable auditing procedures and technical recommendations Details of security weaknesses in the AS/400 system A complete overview of AS/400 security, from resource authorization models to today's client/server environments AS/400 Security in a Client/Server Environment provides a complete guide for IT managers; systems developers, designers, analysts, and programmers; and database developers and administrators, as well as anyone interested in the wider context of the AS/400's evolution.

Java distributed computing, Intranets, and Windows NT: the face of client/server computing continues to evolve. Readers can keep current with this top-selling and comprehensive reference.

Open Client/Server Computing and Middleware provides a tutorial-oriented overview of open client/server development environments and how client/server computing is being done. This book analyzes an in-depth set of case studies about two different open client/server development environments—Microsoft Windows and UNIX, describing the architectures, various product components, and how these environments interrelate. Topics include the open systems and client/server computing, next-generation client/server architectures, principles of middleware, and overview of ProtoGen+. The ViewPaint environment, ProtoView screen manager, SQLView visual database access, and ProtoView WinControl library are also elaborated. This text likewise covers the interaction with db-UIM/X, widgets and building interfaces, network object toolkit, and integration of cross-platform components. This publication is suitable for computing professionals and researchers interested in open client/server computing.
