Systems Analysis and Design - Tapa dura

Put SAD into action! You can't truly understand Systems Analysis and Design (SAD) by only reading about it; you have to do it. In "Systems Analysis and Design, Third Edition", Dennis, Wixom, and Roth offer a hands on approach to actually doing SAD. Building on their experience as professional systems analysts and award winning teachers, these three authors capture the experience of actually developing and analyzing systems. They focus on the core set of skills that all analysts must possess from gathering requirements and modeling business needs, to creating blueprints for how the system should be built. This book features new and expanded coverage, including expanded coverage of functional and nonfunctional requirements; new event action lists; a new extended example of process modeling and data modeling; expanded discussion of the use and interpretation of the weighted alternative matrix as well as RFPs, RFI, and RFQs; a new emphasis on the Migration Plan; and new coverage of business contingency planning during implementation. It focuses on doing SAD. After presenting the how and what of each major technique, the text guides you through practice problems and invites you to use the technique in a project. It follows a project based approach. Topics are presented in the order in which an analyst would encounter them in a typical project. Real life examples include a running case, which serves as a template that you can apply to your own work, and Concepts in Action examples that describe how real companies succeeded (and failed) in performing SAD activities. Object oriented concepts and techniques are included throughout the book, and a final chapter focuses on the major elements of UML. Coverage is updated to reflect the innovations of UML Version 2.0. Student Website includes hands on exercises, templates for project deliverables, PowerPoint slides, and relevant Internet links.
