Summary

Systems Analysis and Design in a Changing World, Fourth Edition maintains its popular and real-world coverage of both approaches to this discipline: the traditional (structured) and the object-oriented (OO). This new edition is even easier to navigate with its streamlined Table of Contents and distinctive treatment of each approach. Added perspective is provided for students via the running case studies and a new "Best Practices" feature. Updated to UML 2.0, advanced object-oriented topics are dispersed throughout the text as well as extensive coverage of the latest concepts in project management. Book jacket.
