Oracle's Designer/2000 gives you powerful tools for information systems development, but its sophistication makes it very challenging to learn. In Rapid Application Development with Oracle® Designer/2000, the authors' "fast-path" approach puts Designer/2000 essentials into your hands quickly and shows how to make the most of the toolset in designing and implementing information systems that effectively serve your clients' needs.

The book shows how to incorporate Designer/2000 into every phase of development, from interviewing business executives about their informational needs through implementing the final application. The book takes an example organization's development team through the planning, analysis, data design, and implementation of a sample Oracle7 database and an application built from Oracle Forms, Oracle Reports, and Visual Basic modules. In the process, it describes every Designer/2000 tool and demonstrates how to put each to work in real-world applications development.

Specifically, you will learn how to apply such Designer/2000 tools as the Matrix Diagrammer, Entity-Relationship Diagrammer, Repository Object Navigator, Database Design Wizard, Module Structure Diagrammer, and more. The book features extensive coverage of Designer/2000's flexible yet complex application generators, presenting the many capabilities and options of the Forms Generator, screen reports, and the Visual Basic Generator. Furthermore, you will find information on all the newest developments, including the WebServer Generator, the MS Help Generator, the Graphics Generator, and the C++ Object Layer Generator. For those who have little or no experience with Designer/2000, the book also includes a comprehensive overview providing a brief explanation of each Designer/2000 tool.

Preface

A great deal has changed in the information system (IS) industry since we wrote Rapid Development with Oracle CASE in 1992. Today there is an ever greater emphasis on:

  • Distributed client/server development

  • Graphical user interfaces (GUI)

  • Object-oriented tools and techniques

  • The creation of World Wide Web applications for viewing and reporting on enterprise-wide information.

Of course, many fundamentals of the system development process remain with us, for example, the challenge of managing complex, large-scale, often geographically distributed projects. And coupled with this is the ever-present pressure created by time and resource constraints.

All these factors beg for methods and tools that can squarely address their impact. Designer/2000 provides both the methodology and the technology that organizations need to manage this increasing complexity and accelerating rate of change.

When we thought about how to approach the Designer/2000 product set, we tried to consider these changes. We also reflected on the many responses we had received to Rapid Development with Oracle CASE: A Workshop Approach, the predecessor to this book. For example, we wanted to cover the operation of the application generators in more detail, since these products provide such a wealth of features and options. We also realized the need for a brief tutorial to help beginners navigate through the tools. Fortunately, we've been able to include all these enhancements (in other words, we have completely rewritten this book), and we believe our readers will receive significantly more assistance with their Oracle development efforts as a result.

Once again, out context for examining these tools and techniques is a rapid application development (RAD) workshop. We select a functional area of a client's organization in order to take their development team through Analysis to the implementation of a sample Oracle7 database and an application built from Oracle Forms, Oracle Reports, and Visual Basic modules. But this time we go even further by adding three more chapters that examine each of the application generators.

This combined approach allow us to:

  • Indicate the "red thread" of essential actions needed to complete a Designer/2000 project, beginning with business modelling and continuing through the implementation of a functioning system.

  • Provide detailed instructions on using the highly flexible (and complex) Forms, Reports, and Visual Basic Generators that our clients and readers have been asking for.

We are very excited about the quality of this book, and we sincerely hope it contributes to the success of all your future Designer/2000 projects.

Acknowledgements

By virtue of the complexity of Designer/2000 and the ambition of our aims for this book, we have needed (and received) considerable expert help from colleagues in the Oracle community. Once again, we need to thank Liz Johnson for providing us with her excellent technical editing skills. We are also indebted to several software developers, documenters, and courseware developers for their very thorough and knowledgable reviews. These include Andy Page, Bill Kukstas, Amy Coppola, Keith Bremer, Ian Neall, Carl Gohringer, Rosie Harvey, Matt Gridley, and Robin Fisher.
