Essentials of Systems Analysis and Design

Provides the latest in systems analysis and design, including:

• Expanded coverage of business processes. Process modeling is at the heart of systems analysis and design. Data flow diagrams have been a staple of this book since its first edition, but now they are framed in the context of business process diagramming. The beginning of Chapter 6 has been rewritten to show how data flow diagrams are just one of many common methods for modeling business processes. Business processes are defined and illustrated before the discussion of data flow diagrams begins.
• Updated illustrations of technology. Screen captures have been updated throughout the text to show examples using the latest versions of programming and Internet development environments, and user interface designs.
• Updated content. Throughout the book, the content in each chapter has been updated where appropriate.
