Ayer helps application programmers keep up, walking them through the entire process of object-oriented, client/server application development. The book describes techniques for the analysis, design, development and implementation of a C/S-based application. Ayer thoroughly covers all OOP systems design hardware and network issues. Includes case studies and diagrams throughout.

Client/server applications are of increasing importance in industry; they are a significant first step towards a global distributed processing model. A very recent response to this trend is the Distributed Computing Environment (DCE) of the Open Software Foundation (OSF), the emerging new industry standard for distributed processing. The papers in this volume discuss the client/server approach based on DCE, illustrating and analyzing the functionality of important DCE components and applications. A number of contributions also focus on new models beyond traditional client/server processing and beyond DCE. The papers in this volume were presented at the International Workshop on the OSF Distributed Computing Environment, held in Karlsruhe, Germany, October 7-8, 1993. Following an introductory chapter, the contributions are grouped into parts on DCE analysis and comparison, application support, methods and tools, RPC extensions, and object-based systems.

For computer science courses focusing on distributed systems. This book systematically answers critical management and technical questions about the modern IT infrastructure, in particular, middleware.

Client/server and distributed technologies have made great strides since their emergence in the late 1980s to become very popular in the IT industry today. This book illustrates techniques not only for designing GUI client/server applications, but also for managing complex application environments containing both legacy and new applications. Topics covered in this book include - The what, when and how of the three tier client/server model - Coupling and dependency: key design factors in distributed systems - Distributed application design alternatives for the enterprise - The Federated application structure for integrating the applications of the enterprise - A real-life case study of a major financial institution - Systems Architects and senior technical staff Project Managers and Software Engineers involved with or interested in client/server computing, and final year undergraduate and postgraduate students will find this book useful.

Annotation Advanced guide to distributed applications using PowerBuilder 9. This book addresses development Web and Intranet-based systems, including Web Services, Portals, Application-Servers, XML, and Mobile Access. Content provides both specific implementation techniques and architectural patterns for distributed application development. PowerBuilder 9, to be released Q4 2002, introduces many highly-anticipated distributed development features including support for Web Services and Java application servers. Version 9 of PowerBuilder introduces many features designed specifically to blend the traditional strength of PowerBuilder as a rapid Client/Server application development tool with the new emerging models for distributed application development. PowerBuilder developers need PowerBuilder-specific information on interacting with Java application servers, such as WebSphere, WebLogic, and Sybases Enterprise Application Server (EAServer), and Web Service development. This book presents the new capabilities of PowerBuilder 9 along with the architecture and patterns required to create distributed systems in PowerBuilder. William Green and his team of writers are among the most prominent members of the Sybase community, having helped found TeamSybase in 1994. They have written and served on the advisory boards for every major PowerBuilder publication and have authored three books -- PowerBuilder 5 Object-Oriented Design and Development, PowerBuilder Foundation Class (PFC), and Secrets of the PowerBuilder Masters. They respond to several hundred newsgroups and listserv postings daily. They are active consultants implementing PowerBuilder-based solutions and serve on key community advisory panels within Sybase.
