Content Description

《敏捷软件开发:原则模式与实践》由享誉全球的软件开发专家和软件工程大师Robert C.Martin将向您展示如何解决软件开发人员、项目经理及软件项目领导们所面临的最棘手的问题。这本综合性、实用性的敏捷开发和极限编程方面的指南,是由敏捷开发的创始人之一所撰写的。1.讲述在预算和实践要求下,软件开发人员和项目经理如何使用敏捷开发完成项目;2.使用真实案例讲解如何用极限编程来设计、测试、重构和结对编程;3.包含了极具价值的可多次使用的C++和JAVA源代码;4.重点讲述了如何使用UML和设计模式解决面向客户系统的问题。
Author Description

Robert C.Martin是Object Mentor公司的总裁。Martin和他的软件咨询队伍使用面向对象设计、模式、UML、敏捷方法学和极限编程,在世界各地都有他们的客户。他还是好几本畅销书的作者。他还是1996-1999年《C++ Report》杂志的总编,并多次在国际会议和展览中发表富有特色的演讲。
Comments

第13届软件开发震撼大奖获奖作品;国际软件工程和开发大师最新力作;众多名家一致推荐的敏捷开发指南;软件工程发展史上的里程碑性巨著。希望你能喜爱这本书。希望你能像我一样学着以创建美的软件而骄傲,并享受其中的快乐。如果你从本书中略微看到了这种快乐,如果本书使你感受到了这种骄傲,如果本书点燃了你内心欣赏这种美的火花,那么就远超过我的目标了。

Book Abstract

7.2 设计的臭味——腐化软件的气味
当软件出现下面任何一种气味时,就表明软件正在腐化。
僵化性(Rigidity):很难对系统进行改动,因为每个改动都会迫使许多对系统其他部分的其他改动。
脆弱性(Fragility):对系统的改动会导致系统中和改动的地方在概念上无关的许多地方出现问题。
牢固性(Immobility):很难解开系统的纠结,使之成为一些可在其他系统中重用的组件。
粘滞性(Viscosity):做正确的事情比做错误的事情要困难。
不必要的复杂性(Needless Complexity):设计中包含有不具任何直接好处的基础结构。
不必要的重复(Needless Repetition):设计中包含有重复的结构,而该重复的结构本可以使用单一的抽象进行统一
。晦涩性(Opacity):很难阅读、理解。没有很好地表现出意图。
1.僵化性
僵化性是指难以对软件进行改动,即使是简单的改动。如果单一的改动会导致有依赖关系的模块中的连锁改动,那么设计就是僵化的。必须要改动的模块越多,设计就越僵化。
大部分的开发人员都以这样或者那样的方式遇到过这种情况。他们会被要求进行一个看起来简单的改动。他们看了看这个改动并对所需的工作做出了一个合理的估算。但是过了一会儿,当他们实际进行改动时,会发现有许多改动带来的影响自己并没有预测到。他们发现自己要在庞大的代码中搜寻这个变动,并且要更改的模块数目也远远超出最初估算。最后,改动所花费的时间要远比初始估算长。当问他们为何估算得如此不准确时,他们会重复软件开发人员惯用的悲叹,“它比我想像的要复杂得多!”
2.脆弱性
脆弱性是指,在进行一个改动时,程序的许多地方就可能出现问题。常常是,出现新问题的地方与改动的地方并没有概念上的关联。要修正这些问题就又会引出更多的问题,从而使开发团队就像一只不停追逐自己尾巴的狗一样(忙得团团转)。
随着模块脆弱性的增加,改动会引出意想不到的问题的可能性就越来越大。这看起来很荒谬,但是这样的模块是非常常见的。这些模块需要不断地修补——它们从来不会被从错误列表中去掉,开发人员知道需要对它们进行重新设计(但是谁都不愿意去面对重新设计中的难以琢磨性),你越是修正它们,它们就变得越糟。
3.牢固性
牢固性是指,设计中包含了对其他系统有用的部分,但是要把这些部分从系统中分离出来所需要的努力和风险是巨大的。这是一件令人遗憾的事,但却是非常常见的事情。
4.粘滞性
粘滞性有两种表现形式:软件的粘滞性和环境的粘滞性。
当面临一个改动时,开发人员常常发现会有多种改动的方法。其中,一些方法会保持设计;而另外一些会破坏设计(也就是生硬的手法)。当那些可以保持系统设计的方法比那些生硬手法更难应用时,就表明设计具有高的粘滞性。做错误的事情是容易的,但是做正确的事情却很难。我们希望在软件设计中,可以容易地进行那些保持设计的变动。
