SQL, or Structured Query Language, is a universal tool for creating, managing, and querying relational databases such as SQL Server, PostgreSQL, and Oracle. For data analysts, SQL is a super tool, allowing them to go beyond typical spreadsheet editors and business intelligence systems. At the same time, SQL is intuitive and surprisingly simple: with a little practice, you'll easily extract data, rebuild tables, and create vibrant, visual reports and presentations!

This book is designed for data analysts and beginning IT professionals, including those with no experience working with relational databases. It features 24 compact lessons covering key aspects of SQL, such as extracting, filtering, and processing data. Each lesson concludes with a hands-on exercise lasting approximately 15 minutes. Before you know it, you'll be writing effective queries that return exactly the data you need. Over time, you will develop a valuable intuitive understanding of how databases function in real-world business scenarios.
