问题 问答题 简答题

阅读下列说明,回答问题1至问题4,将解答填入答题纸的对应栏内。【说明】某信息系统开发公司承担了某企业的ERP系统开发项目,由项目经理老杨带领着一支6人的技术团队负责开发。由于工期短、任务重,老杨向公司申请增加人员,公司招聘了2名应届大学毕业生小陈和小王补充到该团队中。老杨安排编程能力强的小陈与技术骨干老张共同开发某些程序模块,而安排编程技术弱的小王负责版本控制工作。在项目开发初期,小陈由于不熟悉企业的业务需求,需要经常更改他和老张共同编写的源代码文件,但是他不知道哪个是最新版本,也不知道老张最近改动了哪些地方。一次由于小王的计算机中了病毒,造成部分程序和文档丢失,项目组不得不连续一周加班进行重新返工。此后,老杨吸取教训,要求小王每天下班前把所有最新版本程序和文档备份到2台不同的服务器上。一段时间后,项目组在模块联调时发现一个基础功能模块存在重大BUG,需要调取之前的备份进行重新开发。可是小王发现,这样一来,这个备份版本之后的所有备份版本要么失去意义,要么就必须全部进行相应的修改。项目工期过半,团队中的小李突然离职,老杨在他走后发现找不到小李所负责模块的最新版本源代码了,只好安排其他人员对该模块进行重新开发。整个项目在经历了重重困难,进度延误了2个月后终于勉强上线试运行。可是很快用户就反映系统无法正常工作。老杨带领所有团队成员在现场花费了1天时间终于找出问题所在,原来是2台备份服务器上的版本号出现混乱,将测试版本中的程序打包到了发布版中。

结合案例,请分析为什么要进行配置项的版本控制?

答案

参考答案:

在项目开发过程中,绝大部分的配置项都要经过多次的修改才能最终确定下来。对配置项的任何修改都将产生新的版本。由于我们不能保证新版本一定比旧版本"好",所以不能抛弃旧版本。版本控制的目的是按照一定的规则保存配置项的所有版本,避免发生版本丢失或混淆等现象,并且可以快速准确地查找到配置项的任何版本。

    Mr. Ma, a famous mental doctor (心理医生) from Beijing once said at an important meeting, "Now

many young students can have problems with their minds. Some students become worried because they

have to study very hard. Others have trouble getting on well with people around them like their parents

and classmates. Parents and teachers should care more about this problem."

    Then Mr. Ma gave some examples. A middle school student from Xi'an was doing badly in his lessons.

He thought his teachers and friends often laughed at him, and he became so nervous and worried that one

night he left his home without telling his parents. Another student, a 14-year-old schoolgirl from Shanghai,

was very afraid of exams. While she was reading the exam paper, she couldn't think of anything to write.

    A recent report from a newspaper says about 18% of the young students in Shanghai have mental

problems. They often feel worried and very unhappy. Unluckily many of them won't go and ask for help.

Some think they will look stupid if they go to see a doctor. Others won't talk about their secrets.
