SQL Indexing and Tuning Book: Use the Index, Luke!

Free Online SQL Indexing and Tuning Book: Use the Index, Luke!

“Use the Index, Luke!: A guide to database performance” is a free online SQL indexing and tuning book by Markus Winand. This book is for developers; it avoids unnecessary details about database internals.


This book covers everything developers need to know about indexes—and nothing more. To be more precise, the book covers the most important index type only: the B-Tree index. The B-Tree index works almost identical in various databases. The book uses the terms of the Oracle database only, but the principles apply to other databases as well. Side notes provide relevant information for MySQL, PostgreSQL and Microsoft SQL Server.

The structure of the book is tailor-made for developers; most of the chapters correspond to a specific part of an SQL statement.
