Systems Analysis and Design
Wanted: Intelligent, Motivated Individuals for High-Paying Systems Analyst and Design Positions! This practical, no-nonsense textbook provides you with the rich foundation you need to enter the exciting field of systems analysis and design, and helps you gain the core skills that will ensure a successful and rewarding career! Each chapter in the text describes one part of the SAD process, provides clear explanations on how to do it, gives a detailed example, and then includes exercises that allow you to practice what you've learned. The focus is on the specific tasks that analysts need to accomplish over the course of a project, and the deliverables that will be produced from the tasks. As you complete the book, tasks are checked off and deliverables completed and filed in a Project Binder. Along the way, you are reminded of your progress using roadmaps that indicate where the current task fits into the larger context of SAD. The result is that you come to understand how to use this process in a real situation, and acquire key skills that you'll use throughout your career. Other Features of the Text
