接下来解释主要几种开发方法。
结构化方法:是一种传统的信息系统开发方法,基本思想是将系统生命周期划分为系统规划、系统分析、系统设计、系统实施、系统维护等阶段。这种方法遵循系统工程原理,按照事先设计好的程序和步骤,使用一定的开发工具,完成规定的文档,在结构化和模块化的基础上进行信息系统的开发工作。
面向对象方法:该方法认为,客观世界是由各种对象组成的,任何事物都是对象,每个对象都有自己的运动规律和内部状态,都属于某个对象类,是该对象类的一个元素。
原型法:也称为快速原型法。它是一种根据用户初步需求,利用系统开发工具,快速地建立一个系统模型展示给用户,在此基础上与用户交流,最终实现用户需求得信息系统快速开发的方法。
迭代方法:像结构化方法是强调软件开发工作得序列化过程,其中一个活动需要在另一个开始之前完成。在迭代式过程中,每个阶段都包括不同比例的所有活动。
