There's no easier, faster, or more practical way to learn the really tough subjects. "SQL Demystified" explains how to use SQL (Structured Query Language) - the ubiquitous programming language for databases. Readers will learn to create database objects, add and retrieve data from a database, and modify existing data. This self-teaching guide comes complete with key points, background information, quizzes at the end of each chapter, and even a final exam. Simple enough for beginners but challenging enough for advanced students, this is a lively and entertaining brush-up, introductory text, or classroom supplement.
