Summary

This groundbreaking text provides the most comprehensive, balanced and up-to-date coverage of systems analysis and design available. The Third Edition maintains the dual focus on the concepts and techniques from both the traditional, structured approach and the object-oriented approach to systems development. Instructors have the flexibility to emphasize one approach over the other, or both, while referring to one integrated case study that runs through every chapter. The authors emphasize fundamentals of lasting value, while addressing the diverse development environments available today.
