"Gunnar and Karin have not only defined a large collection of use-case patterns and examples of how specific usages are to be modeled in a use-case model, they have also provided an accurate, complete, and comprehensible description of the constructs used in use-case modeling... I am impressed by this book." —From the Foreword by Ivar Jacobson Employ the proven concept of design patterns to build more accurate, usable, and maintainable use-case models This book brings together dozens of proven patterns for creating use cases that more accurately reflect real requirements, are easier to translate into working systems, and are simpler to maintain. Utilizing these patterns, architects, analysts, engineers, and managers can leverage decades of hard-earned knowledge to achieve far better results, far more quickly. The authors carefully describe how each pattern works, what problems it is intended to solve, and the consequences associated with using it. All patterns are supported with detailed examples and platform-independent class models that demonstrate how they may be realized. All constructs and diagrams reflect the current UML 2.0 standard. This book also includes an insightful use-case primer that will be indispensable both to novices and veteran modelers seeking to become more effective. Coverage includes Modeling rules that lead to more comprehensible, maintainable, and correct models Patterns for structuring, layering, mapping, sequencing, and viewing use cases more effectively Blueprints for security, legacy integration, data input/ output, task scheduling, and reporting Constructing use cases that separate mandatory elements from optional parts that can be delivered separately Incorporating business rules in use-case modeling Practical techniques for documenting use cases more effectively When to use multiple patterns and blueprints together Identifying and avoiding eight common mistakes in use-case modeling: guidance for designers and reviewers Examples from a wide range of application domains Rely on this book as the world's #1 reference to reusable use-case solutions— and as a catalyst for inspiration in all your use-case modeling projects. © Copyright Pearson Education.
