System analysis and design methods = 系统分析与设计方法 / 5th ed., photocopy ed.

　　 More than ever, today's students are "consumer-oriented," due in part to the changing world economy that promotes quality, competition, and professional currency. They expect to way from a course with more than a grade and a promise that they'll someday appreciate what they've learned. They want to "practice" the applications of concepts. As with the previous editions of this book , we wrote it to: (1)balance the coverage of concepts, tools, techniques, and their application, (2)provide the most examples of system is and design deliverables available in any book, and (3)balance the coverage of classical methods (such as structured analysis and information engineering) and emerging methods (e.g., object-oriented analysis and rapid application development). Additionally, we wrote the textbook to serve the reader as a post-course, professional reference for best current practices.
