## 譯序

> 不懂資料庫的全棧工程師不是好架構師
>
> —— Vonng

​	現今，尤其是在網際網路領域，大多數應用都屬於資料密集型應用。本書從底層資料結構到頂層架構設計，將資料系統設計中的精髓娓娓道來。其中的寶貴經驗無論是對架構師，DBA、還是後端工程師、甚至產品經理都會有幫助。

​	這是一本理論結合實踐的書，書中很多問題，譯者在實際場景中都曾遇到過，讀來讓人擊節扼腕。如果能早點讀到這本書，該少走多少彎路啊！

​	這也是一本深入淺出的書，講述概念的來龍去脈而不是賣弄定義，介紹事物發展演化歷程而不是事實堆砌，將複雜的概念講述的淺顯易懂，但又直擊本質不失深度。每章最後的引用質量非常好，是深入學習各個主題的絕佳索引。

​	本書為資料系統的設計、實現、與評價提供了很好的概念框架。讀完並理解本書內容後，讀者可以輕鬆看破大多數的技術忽悠，與技術磚家撕起來虎虎生風🤣。

​	這是2017年譯者讀過最好的一本技術類書籍，這麼好的書沒有中文翻譯，實在是遺憾。某不才，願為先進技術文化的傳播貢獻一分力量。既可以深入學習有趣的技術主題，又可以鍛鍊中英文語言文字功底，何樂而不為？



## 前言

> 在我們的社會中，技術是一種強大的力量。資料、軟體、通訊可以用於壞的方面：不公平的階級固化，損害公民權利，保護既得利益集團。但也可以用於好的方面：讓底層人民發出自己的聲音，讓每個人都擁有機會，避免災難。本書獻給所有將技術用於善途的人們。

---------

> 計算是一種流行文化，流行文化鄙視歷史。 流行文化關乎個體身份和參與感，但與合作無關。流行文化活在當下，也與過去和未來無關。 我認為大部分（為了錢）編寫程式碼的人就是這樣的， 他們不知道自己的文化來自哪裡。
