The philosophy of Marvin Gore and John Stubbe has always been to give students a solid foundation for applying learned techniques in the development of a computer information system. The goal of Contemporary Systems Analysis, 5/e is to maintain the integrity and tradition of the Gore/Stubbe style, while strengthening the coverage of current technology and trends in the field. Contemporary Systems Analysis presents a balanced approach to the four phases of the systems development life cycle (SDLC): analysis, design, development, and operation. As indicated by the change in the title, this edition acknowledges the effects of current technology on systems development and includes coverage of the latest trends, approaches, and software. CASE tools are integrated with the traditional, thorough presentation that is the trademark of the Gore/Stubbe text.
