Systems Analysis and Design: A Case Study Approach [antikvár]

prefoce This book proposes a new thrust in teaching the traditional systems analysis and design course by stressing an interactive and distributed data processing approach to systems. The concepts presented here enable a systems analyst to operate successfully in the 80s and beyond: a comprehensive treatment of design theory and principles, and great emphasis on the application of systems design to the real world. More specifically, several chapters ofthe text are devoted to a typica! systems design case study-namely, the ABC Company-whereby students are shown how to design an order-entry system. Based upon this illustrated case, they are then required to design a finished product inventory system or an accounts receivable system that complements the one presented. Thus, students are exposed to the underlying principles and practices of systems analysis and design, as weil as given an opportunity to design an interactive computerized (management information) system in a distributed processing environment, currently operated in a batch processing mode. Additionally, emphasis is placed on relating the humán factor to the new systems design. Such a presentation helps alleviate students' fear that computer systems are impersonal and insensitive to the humán element in business, government, and education today. Consideration for the humán element goes a long way toward resolving the problem that people are just numbers; the focus in this book is on utilizing the vast capabilities of personnel at all levels in an organization. Within the foregoing framework of principles and practices in systems analysis and design, the book contains certain student-oriented learning features. These include chapter objectives and outlines to help students place each chapter in its proper perspective. ÍX
