…理解软件。所有软件都在和数据打交道。如果你对数据没有深刻的理解，就绝不可能真正搞懂软件。我读过最好的书之一就是 Lex de Haan 和 Toon Koppelaars 写的《数据库专业人员应用数学》（Applied Mathematics for Database Professionals）。我觉得它就是数据库领域的 SICP。如果你想严肃认真地对待数据，就必须读懂它。而如果你想写好…
…understanding software. All software deals with data. If you don't have a good understanding of data, you are never going to have a good understanding of software. One of the best books I've ever read was Applied Mathematics for Database Professionals by Lex de Haan, and Toon Koppelaars. I think that's the database equivalent of SICP. You need to read it and understand it if you want to seriously deal with data. And you want to if you want to write…
Lex de Haan 和 Toon Koppelaars 的《数据库专业人员应用数学》（Applied Mathematics for Database Professionals）——一本从逻辑和离散数学讲起、相对温和的数据库理论入门书。Ralph Kimball 和 Margy Ross 的《数据仓库工具箱》（The Data Warehouse Toolkit）——即便你做的是 OLTP 业务，了解一下也大有裨益…
Lex de Haan and Toon Koppelaars, Applied Mathematics for Database Professionals -- a fairly gentle introduction to database theory starting with logic & discrete math Ralph Kimball and Margy Ross, The Data Warehouse Toolkit -- even if you're in an OLTP context, it's useful to know…
……从他的书里，除了深深的恼火，部分原因是他那种绝对的迂腐……我最后是靠 Alan Beaulieu 的一本温和入门书学会了 SQL。我偶然撞见另一本讲理论的书：《Applied Mathematics for Database Professionals》，作者是 Lex deHaan 和 Toon Koppelaars。也许这几位作者会仁慈地教我关系理论。但请避开 C. J. Date 的书。而且写书或者试图解释什么东西的时候，别变成他那样……
…from his books, except a deep irritation partly due to his absolute pedantry... I finally learned SQL with a gentle introduction by Alan Beaulieu. I stumbled upon another book that's about the theory: Applied Mathematics for Database Professionals, by Lex deHaan, and Toon Koppelaars. Maybe these authors will benevolently teach me relational theory. But please avoid C. J. Date's books. And don't be him when writing a book or trying to explain something…
