Practical SQL 在線電子書 圖書描述

Practical SQL is an approachable and fast-paced guide to SQL (Structured Query Language), the standard programming language for defining, organizing, and exploring data in relational databases. The book focuses on using SQL to find the story your data tells, with the popular open-source database PostgreSQL and the pgAdmin interface as its primary tools.

You’ll first cover the fundamentals of databases and the SQL language, then build skills by analyzing data from the U.S. Census and other federal and state government agencies. With exercises and real-world examples in each chapter, this book will teach even those who have never programmed before all the tools necessary to build powerful databases and access information quickly and efficiently.

You’ll learn how to:

Create databases and related tables using your own data

Define the right data types for your information

Aggregate, sort, and filter data to find patterns

Use basic math and advanced statistical functions

Identify errors in data and clean them up

Import and export data using delimited text files

Write queries for geographic information systems (GIS)

Create advanced queries and automate tasks

Learning SQL doesn’t have to be dry and complicated. Practical SQL delivers clear examples with an easy-to-follow approach to teach you the tools you need to build and manage your own databases.

This book uses PostgreSQL, but the SQL syntax is applicable to many database applications, including Microsoft SQL Server and MySQL.
