 在2010年冬天的时候,我们前单位(晋能信工)把我们送到了北大青鸟培训了两个月,最后,我还是没有考试过了。我觉得我不是学习计算机的一块料。一恍,十年过去了,我也不知道我也干什么的一块料。被命运牵着鼻子走。我是一个胆小懦 弱而又不善言辞的人。一味地去听别人,看别人。从来也不知道自己是一个什么人,也不知道自己能干点啥。喜欢看一些不合时书,比如周易、韩非子之类的书。

       在晋能信工,我也干了7年多,从2009年到2015年。这7年中,我看了不少的计算机方面书,可是自己却不会写一个"hello word!"。也许,这是从事过计算机人的最大耻辱。我想自学一下程序,顺便也提升一下自己的证书历程。上了十年班了,一个证书也没考下来。说起来,还嘲人了。蝎体斯人了。

  英文不是中文,我连中国话也咬文嚼不清,有资格看英文类的书籍吗?

  在我四婶住院期间,我四婶的姐姐说过,一个事情,说的是一个小学老师给小朋友们上学,台上的老师说一句:“open your book! open your eyes! 打开你的书,打开你的眼睛!”下边的一个小朋友说:“老师不对,应该是翻开你的书、睁开你的眼睛!”这句话,在我心里翻了好几次。语言的翻译必须符合国语的语序和语言习惯。

    好吧!我也想翻译一些东西。自己还想*译一些东西。可是,我的才华够吗????

 英语单词,还没认识几个,就想翻译一些东西,就凭看过几年的数据库代码?是不是把自己看的太高了,还是我真得有这样的天赋了。

  早上起来,还是看点书吧!只有书中的未知,才知充实自己。虽然是一页书,但是还是看了看。

 

 

  

Preface 

Background

The history of database research over the past 30 year is one of exceptional productivity that led to the database system becoming arguably the most important development in the field of software engineering. The database is now the underlying framework of the information system and has fundamentally changed the way many organizations operate.In particular, the developments in this technology over the last few years have produced systems that  are more powerful and more intuitive to use. This development has resulted in increasing availability of database systems for a wider variety of users. Unfortunately, the appearent simplicity of these systems has led to users creating databases and applications without the necessary knowledge to produce an effective and efficient system. And so the "software crisis" or, as it is sometimes referred to the "software depression" continues.   

  The original stimulus for this book came from the author's work in industry, providing consultancy on database design for new software systems or, as often as not, resolving inadequacies with existing systems. In addition, the authors' move to academia brought similar problems from different users--students. The objectives of this book, therefore, are to provide a textbook that introduces the theory behind databases as clearly as possible and, in particular, to provide a methodology for database design that can be used by both technical and nontechnical readers.

 

Pre--face   脸的前面,是什么是?不知道,说实话,这个词以前见过,但是想不起是什么意思。也不知道是什么意思。也许就是一个前言的意思吧。

Back--ground . ground 是大地的意思,Background是什么意思。是背景的意思吗/

睡吧!看书是一件很痛苦的事情,也许,我是习惯学习吧!小学时,学习还行,初中就不行了。
