Publisher's Synopsis
This book explains how to use relational databases and SQL - the language that is used to access them. This book describes the database concepts, including the tricky details, in plain English, with real-world examples. It does mention the mathematical terms that are often used to label these concepts so that readers will know what they are, but otherwise uses plain English terms that you will hear in practical database projects. This book describes techniques to make our databases accurate, fast and easy to change. We avoid bureaucracy and focus on what works, based on decades of work in business and public-sector projects. The book covers all the leading relational databases including: PostgreSQL, MySQL, Microsoft SQL Server, Oracle, DB2 and others.
