七周七數據庫

如今，我們要面對和使用的數據正在變得越來越龐大和復雜。如果說數據是新的石油。那么數據庫就是油田、煉油廠、鉆井和油泵。作為一名現代的軟件開發者，我們需要了解數據管理的新領域，既包括RDBMS，也包括NoSQL。《七周七數據庫》遵循《七周七語言》的寫作風格和體例，帶領你學習和了解當令最熱門的開源數據庫。在簡單的介紹之后，《七周七數據庫》分章介紹了7種數據庫。這些數據庫分別屬于5種不同的數據庫風格，但每種數據庫都有自己保存數據和看待世界的方式。它們依次是PostgreSQL、Riak、ApacheHBase、MongoDB、ApacheCouchDB、Neo4J和Redis。《七周七數據庫》將深入每一種數據庫，介紹它們的優勢和不足，以及如何選取一種最符合你的應用需求的數據庫。《七周七數據庫》適合數據庫架構師、數據庫管理員，以及想要了解和學習各種NoSQL數據庫技術的程序員閱讀。《七周七數據庫》將幫助讀者了解、選擇和應用這些數據庫，從而更好地發揮日益增長的大數據的能力。

循序漸進學Spark

本書以小象學院git項目方式管理。感謝姜冰鈺、陳超、冼茂源等每一位內容貢獻者，感謝他們花費大量時間，將自己對Spark的理解加上在實際工作、學習過程中的體會，融匯成豐富的內容。與企業不斷涌現的對大數據技術的需求相比，大數據人才還存在很大缺口，對大數據技術充滿期許的新人正在源源不斷地加入這個領域。在小象學院的教學實踐過程中，我們發現，一本能完整系統地介紹Spark各模塊原理并兼顧使用實戰的書，對于初入大數據領域的技術人員至關重要。于是，我們根據日常積累的經驗，著成本書。
