上一篇,架构设计的UML图形思考 ,简介了图形思考设计.表达设计对于架构师的重要意义,以及简介了使用统一建模语言UML描写叙述类以及类之间的继承关系,这样的描写叙述还停留在写代码,表达的但是说是怎样写出类代码来,接下来我们要学习用UML表示业务的内涵,分析业务的内涵,加以抽象,将细节隐藏起来,用UML图象表现出来. 一.系统分析 什么是系统分析? 大多数情况下,一看到系统分析这个字眼.我们常常迷失于其字面的意义,以为分析的对象是「系统」.这是一种常见的迷失! 事实上.分析的对象是系统所处的「业务…

写在前面: 上一篇记录了Socket聊天程序的客户端设计,为了记录的完整性,这里还是将Socket聊天的最后一个模块--Common模块记录一下.Common的设计如下: 功能说明: Common模块主要是数据交互,这里使用JSON数据进行交互,common模块定义了各类交互信息,SendHelper实现的socket信息的传送,I18N是语言话,ConstantValue是系统中的配置以及常量(这里常量都是用接口,这个可能不太好),对于ReturnMessage拥有一系列的DTO作为其cont…

Ok, Go ahead. 1 (a) (b) (c) (d) 2 注:union 在 Common Lisp 中的作用就是求两个集合的并集.但是这有一个前提,即给的两个列表已经满足集合的属性了.具体的操作过程似乎是对第一个 list 中的每一个元素在第二个 list 中查找,如无则标记一下:待第一个 list 的所有元素在第二个 list 中查完以后将所有标记过的元素放入一个 list 中与第二个 list 进行合并.这意味着,如果刚开始给的两个 list 不完全满足集合的属性,则会有重复出现…

Write a function to find the longest common prefix string amongst an array of strings. 这道题让我们求一系列字符串的共同前缀,没有什么特别的技巧,无脑查找即可,我们定义两个变量i和j,其中i是遍历搜索字符串中的字符,j是遍历字符串集中的每个字符串.这里将单词上下排好,则相当于一个各行长度有可能不相等的二维数组,我们遍历顺序和一般的横向逐行遍历不同,而是采用纵向逐列遍历,在遍历的过程中,如果某一行没有了,说明其为…
