SC Chapter 1:Views and Quality Objectives of Software Construction Review

Chapter 1: Views and Quality Objectives of Software Construction

1.1 Multi-Dimensional Views of Software Construction

Outline

Multi-dimensional software views
–By phases: build-and run-time views
–By dynamics: moment and period views
–By levels: code and component views
–Elements, relations, and models of each view
Software construction: transformation between views
–∅->Code
–Code ->Component
–Build-time ->Run-time
–Moment ->Period


我们这学期关注的重点:

1.2 Quality Objectives of Software Construction

上一章讲的是我们如何软件构造的目标是什么,下面我们介绍如何衡量开发出软件的好坏,虽然标准有许多,一般主要可以分成外部指标和内部指标:
external factor:主要反映的是从用户角度层面的指标
internal factor:主要反映的是从开发者角度的指标
指标很多,必然就要涉及tradeoff,但是就现在工业界对软件开发评判的标准,四个因素最为重要:正确性,鲁棒性,可扩展性,可复用性

主要有如下五张图给出的五个指标。
(这也是我们在后续课程章节中需要学习的部分)
