Dennis Alan, Wixom Barbara Haley, Roth Roberta M. Systems Analysis and Design

6th ed. — John Wiley & Sons, 2015. — 489 р. — ISBN 978-1118897843, 1118897846.The 6th Edition of Systems Analysis and Design continues to offer a hands-on approach to SAD while focusing on the core set of skills that all analysts must possess. Building on their experience as professional systems analysts and award-winning teachers, authors Dennis, Wixom, and Roth capture the experience of developing and analyzing systems in a way that students can understand and apply.
With Systems Analysis and Design, 6th Edition, students will leave the course with experience that is a rich foundation for further work as a systems analyst.Acknowledgments.
