Applying Use Case Driven Object Modeling with UML: An

Annotated e-Commerce Example is a practical, hands-on

guide to putting use case methods to work in real-world

situations. This workbook is a companion to Use Case

Driven Object Modeling with UML. It bridges the gap

between the theory presented in the main book and the

practical issues involved in the development of an Internet

e-commerce application.

About the Author

Uniquely conceived as a workbook and featuring as a

running example an e-commerce system for an online

bookstore, Applying Use Case Driven Object Modeling with

UML examines design in detail, demonstrating the most

common design mistakes and the correct design solutions.

The hands-on exercises allow you to detect, identify, and

correct critical errors on your own, before reviewing the

solutions provided in the book.

Structured around the proven ICONIX Process, this

workbook presents a streamlined approach to UML

modeling designed to avoid analysis paralysis without

skipping analysis and design. The book presents the four

key phases of this minimalist approach to use case driven

design--domain modeling, use case modeling, robustness

analysis, and sequence diagramming--and for each topic

provides an overview, detailed discussion, list of common

mistakes, and a set of exercises for honing object modeling

and design skills.

The three chapters on reviews are also unique. The authors

devote a chapter each to requirements review, preliminary

design review, and critical design review. This focus on

"designing quality in" by teaching how to review UML

models fills a major gap in the published literature.

Through examples, Applying Use Case Driven Object

Modeling with UML shows you how to avoid more than

seventy specific design errors, as illustrated by the "Top

10" error lists included as a handy key on the inside covers

and within each chapter. With the information, examples,

and exercises found here, you will develop the knowledge

and skills you need to apply use case modeling more

effectively to your next application.

We dedicate this book to the memory of Tom Johnson,

whose steady and dependable work kept both of us busy

teaching the training workshops that gave us the source

material for this book.

Tom’s untimely passing as the manuscript was in final

production saddened all of us who knew him.

He will be sorely missed.
