Description

Relational databases hold data, right? They indeed do, but to think of a database as nothing more than a container for data is to miss out on the profound power that underlies relational technology. A far more powerful way of thinking lies in relational technologys foundation in the mathematical disciplines of logic and set theory.

Databases contain truths or propositions describing some area of interest such as a business. Those truths are organized into sets. Operations from logic and set theory can be applied to existing sets of truths to derive new sets of truths. Applied Mathematics for Database Professionals introduces you to this way of thinking, to the logic and set theory that underlies relational database technology. All this may sound abstract now, but there are profound benefits from the deeper understanding youll gain from this book. Youll learn to

  • Become a better database designer. Youll make fewer mistakes, and your designs will be more flexible in response to changing data needs.
  • Use the expressive power of mathematics to precisely specify designs and business rules.
  • Communicate effectively about design using the universal language of mathematics.
  • Develop and write complex SQL statements with confidence.
  • Avoid pitfalls and problems from common relational bugaboos such as null values and duplicate rows.

The math that you learn in this book will put you above the level of understanding of most database professionals today. Youll better understand the technology and be able to apply it more effectively. Youll avoid data anomalies like redundancy and inconsistency. Understanding whats in this book will take your mastery of relational technology to heights you may not have thought possible.

This book is reviewed and endorsed by C. J. Date and features a foreword by the same.

描述

關聯式資料庫儲存資料,對吧?它們確實如此,但如果僅僅將資料庫視為資料的容器,那麼就錯過了關聯技術背後深刻的力量。更強大的思考方式在於關聯技術基於邏輯和集合論的數學學科。

資料庫包含描述某個感興趣領域(例如業務)的真理或命題。這些真理被組織成集合。可以將邏輯和集合論的運算應用於現有的真理集合,以推導出新的真理集合。《應用數學與資料庫專業人員》將引導您進入這種思考方式,了解支撐關聯資料庫技術的邏輯和集合論。這一切現在聽起來可能很抽象,但從這本書中獲得的更深刻理解將帶來深遠的好處。您將學會:

- 成為更好的資料庫設計師。您將犯更少的錯誤,並且您的設計將對不斷變化的資料需求更具靈活性。
- 利用數學的表達能力精確地指定設計和業務規則。
- 使用數學這一通用語言有效地溝通設計。
- 自信地開發和撰寫複雜的 SQL 語句。
- 避免常見關聯問題(如空值和重複行)帶來的陷阱和問題。

您在這本書中學到的數學將使您超越當今大多數資料庫專業人員的理解水平。您將更好地理解技術,並能更有效地應用它。您將避免資料異常,如冗餘和不一致。理解這本書的內容將使您對關聯技術的掌握達到您可能未曾想過的高度。

這本書經 C. J. Date 審核並推薦,並由他撰寫前言。
