Discover best practices for turning data into information you can use

Structured Query Language, more popularly known as SQL, is a standard database language used to create, access and manipulate data, and store and maintain information in relational databases such as Access®, SQL Server®, Oracle®, and MySQL®. If that's all you know about SQL, then you're already ahead of the curve! Assuming no prior knowledge of SQL or relational databases, author Alex Kriegel takes you on a voyage of discovery as you learn SQL basics and learn to work with data stored in a relational database. Written in a beginner–friendly tone, this guide walks you through the creation of a sample database that incorporates all the SQL concepts taught throughout the book and also introduces data modeling, query tuning, and optimization.

  • Looks at dynamic SQL, procedural extensions and latest developments in the field

  • Shares best practices for optimizing query performance
