解析:计算机这个术语描述由电子的和机电的部件组合而成的一种设备。计算机本身没有只能,因此称为硬件,仅仅是物理设备。硬件只有和其他要素连接才能使用,所有这些要素即为构成基于计算机信息系统的六要素:硬件、软件、数据/信息、人、操作程序和通信。系统定义为一组相关组件的集合,这些组件相互交互以完成一个任务,以实现一个目标。任何使用信息技术的组织会拥有一个基于计算机的信息系统,给管理人员(和各类员工)提供适当类型的信息以帮助他们做出决策。系统分析和设计是确定系统如何工作然后经过一系列步骤以使其更好。通常,采用系统方法来定义、描述和解决一个问题或满足一个目标。随着时间推移,新的市场机会、政府规定的变化、新技术的出现、公司兼并以及其他方面的发展等,使得组织需要改变其信息系统。当需要改变时,应用系统分析与设计的时机已经成熟。
