This is the #1 selling textbook for the systems analysis and design course. This course is usually taught at the sophomore, junior, senior, and graduate levels to both information systems and business majors. Adoptions of this book can be found at vocational trade schools, community colleges, four-year colleges, and universities. SYSTEMS ANALYSIS AND DESIGN METHODS, 4/E is one of the most practical books on the market to support the core Systems Analysis and Design course. The authors have consciously kept a fine balance between the presentation of concepts and the support of those concepts through the practice of techniques and their application to systems development. The text is written with a lively, conversational tone, which works well with a wide variety of students. A running integrated case demonstrates concepts and techniques by tying the material together at the appropriate level of complexity. With the Fourth Edition, the Whitten text exemplifies how classical and modern techniques can work together in systems development. Traditional structured methodologies and newer object-oriented methods give students an appreciation for the value added by continuously improving tools and techniques. Finally, this edition will be the first on the market to truly incorporate practice with the use of a commercial CASE tool.
