看到两句最经典的话:
1.analysis patterns capture common solutions to recurring problems indo
main
modeling.
2.design patterns capture common solutions to recurring problems in program
design.
 
我觉得设计模式培养的是一种大局观念,就像棋谱中的布局之术。
设计模式是一种经验的累积,没必要死记硬背,只需要知道一种从大局考虑的整体思路,
几乎所有模式的出现都是顺理成章的。
 
设计模式不同于软件工程,前者使软件的开发设计、管理和体系的架构。
如果说软件体系结构是战略思想,那么设计模式就是战术运作。在经历过
多次软件编码后把相同类型的处理进行总结就形成了设计模式,如果他人的总
结不能很好的理解和强般硬套就不会有什么效果,反而会出现失误。
研究需要知识也需要经验,应用的系统分析设计和软件的系统分析设计是
两个方面,但是国内的公司多数总是考虑应用方面的分析设计,二忽略了软件
本身的体系结构的完善,所以有自己的软件结构体系和设计模式的公司不多,
对不同的公司,情况不一样,需要也就不一样

babysloth对johnvlissides说: So what's "compound ptterns" like? could you please say more about the new book?(22:05)那,什么是混合模式呢?您能否给我们介绍一下您的这本新书?
johnvlissides对sealw说: Look how much time it took for the traditional engineering disciplines to develop (100s or 1000s of years)(22:06)针对传统的工业原理进行开发需要多少时间?
johnvlissides对sealw说: we've been writing software for, what, 50 years?(22:06)我们已经写了大约50年软件了。
babysloth对johnvlissides说: How about adding the articles after 1998 of the column to PH 2/e?(22:06)PH第二版中1998年以后各卷增加的文章写得如何?
sealw对johnvlissides说: It's said the code quality of Linux is not as good as that of FreeBSD.(22:06)据说Linux的代码质量没有FreeBSD写得那么好。
johnvlissides对babysloth说: re: compound patterns, check out the corresponding articles at http://www.research.ibm.com/designpatterns/publications.htm#Articles(22:07)混合模式,请到http://www.research.ibm.com/designpatterns/publications.htm#Articles上查看相关的文章。
johnvlissides对babysloth说: it's not a project yet, btw;
just an idea(22:07)顺便说一句,它仍然不是一个项目,而仅仅是一个观念。
sealw对johnvlissides说: Yes. It's the benifits of Open Source software, not only Linux.(22:07)是的。它也获益于公开源代码软件,而不仅仅只有Linux在这样做。
johnvlissides对paofan说: Ido
n't know enough about Linux internals to point out any patterns(22:08)我对Linux内部实现了解得不多,所以无法指出它是否使用了哪些模式。
johnvlissides对paofan说: but I'm sure they're there(22:08)但是我认为他们就是这样的。
johnvlissides对sealw说: it's always a good idea to study exemplary software(22:09)研究这样一个可以作为范例的软件是一个好主意。
 
文章是好文章,可惜没有精辟见解。
建议:
换行。
 
umlchina应该借鉴新浪的嘉宾聊天室,对问题进行筛选,否则简直惨不忍睹。
 
哪有<分析模式>的资料、书籍?
 
本人对设计模式中的创建型模式,进行研究,觉得
Abstructor Factory,Builder,Factory,都是用到面向对象的语言中的多形性的概念。
而且觉得这三种方法有很大的类似,本人还真有点分不开。
 
《设计模式》这东西是团雾,你眼力好(不是砂眼),你就能看的仔细些,否则,哼哼,庸人自扰。
不过,到目前,我才搞清除MVC, 然而,我发现这种结构是那么的美妙,让人无力自拔。
 
先有道,道生机器语言,机器语言生汇编嚣。
汇编器生编译器,然后产生上万种高级语言,
最后产生设计模式。所以要了解设计模式,先要了解道。
 
我想设计模式好比战术套路,如果从实战中将很多经验提高到一定层次后,
形成解决问题的思想,就是战术思想,在战场就叫兵法,在武术上叫拳谱,
在棋艺叫棋经。在程序设计叫设计模式或设计样式。如果不作战,而空练
设计模式叫纸上谈兵。自己体会的战术是游击经验,可能很熟练有效。但
可以博采众长,以便进一步提高。如何提高?学习总结的设计模式是最好的
办法,并投入实际的应用中。

大家觉得那个模式最难理解,最难学?
 
据我所知的23中设计模式中,没有难懂的,只是一个灵活应用,几种模式的相互组合来解决
实际中的问题!这是难点!
 
用好设计模式,还是要在实际的例子中去解释和理解他,比如你不用设计模式,如何设计迷宫?用了设计模式又如何去设计迷宫?
两者比较体会就会受益无穷,当然肯定是很费时的。
设计模式是编程中抽象的抽象,抽象是设计模式的灵魂,懂的多少种设计模式其实不是重要,重要的是你要通过设计模式去学习如何在抽象中再抽象,锻炼提高自己的编程思维能力。

我感觉你一定是高手。
你的问题如果有答案了麻烦给我一份。[:)]
 
不知道设计模式能给我们解决什么问题!大家如此遵崇!又有多少人能运用!
