详细说明： Systems Analysis and Design (SAD) is an exciting, active fi eld in which analysts continually learn new techniques and approaches to develop systems more eff ectively and effi ciently. However, there is a core set of skills that all analysts need to know—no matt er what approach or methodology is used. All information systems projects move through the four phases of planning, analysis, design, and implementation; all projects require analysts to gather requirements, model the business needs, and create blueprints for how the system should be built; and all projects require an understanding of organizational behavior concepts like change management and team building. Today, the cost of developing modern soft ware is composed primarily of the cost associated with the developers themselves and not the computers. As such, object-oriented approaches to developing information systems hold much promise in controlling these costs. Today, the most exciting change to systems analysis and design is the move to object-oriented techniques, which view a system as a collection of self-contained objects that have both data and processes. Th is change has been accelerated through the creation of the Unifi ed Modeling Language (UML). UML provides a common vocabulary of object-oriented terms and diagramming techniques that is rich enough to model any systems development project from analysis through implementation. Th is book captures the dynamic aspects of the fi eld by keeping students focused on doing SAD while presenting the core set of skills that we feel every systems analyst needs to know today and in the future. Th is book builds on our professional experience as systems analysts and on our experience in teaching SAD in the classroom. Th is book will be of particular interest to instructors who have students do a major project as part of their course. Each chapter describes one part of the process, provides clear explanations on how to do it, gives a detailed example, and then has exercises for the students to practice. In this way, students can leave the course with experience that will form a rich foundation for further work as a systems analyst. ...展开收缩
