1、原型:是指模拟某种产品的原始工模型。 2、快速原型方法的核心思想是:在软件开发的早期建立目标软件系统的程方法原型,让用户对原型进行评估并提出修改意见。当原型几经改进最终确定后,它将由软件设计和编码阶段进化

6.1软件维护概述 软件变更可以考虑以下的几个策略: (1)软件维护。不改变软件的基本结构,仅对软件做局部性修改以响应变更的需求。 (2)体系结构转换。是系统的体系结构发生彻底改变的重大的变更。 (3)软件再工程。软件再工程是在

4.1软件设计的概述 一、软件设计的概念 软件设计是一个把软件需求转化 为软件表示的过程,也就是把它加 工为在程序细节上非常接近于源程 序的软件表示(描述)

Interactive Complexity Complexity is a moving target The underlying factor is intellectual manageability 1. A simple\system has a small number of unknowns in its interactions within the system and with its environment 2. A system is intellectually unmanageable when the level of interactions reaches the point where they cannot be thoroughly

Can programming language influence correctness? anguages affect the way we think about problems The tools we use have a profound(and devious) influence on our thinking habits, and, therefore on our thinking abilities?

Fairly primitive and predictive power limited Function Points Count number of inputs and output, user interactions, external interfaces files used Assess each for complexity and multiply by a weighting factor Used to predict size or cost and to assess project productivity

A Testing EXercise (From Glenford Myers: The Art of Software Testing A program reads three integer values from a card. The three values are interpreted as representing the lengths of the sides of a triangle. The program prints a message that states whether the triangle is scalene iso
