Learn how to unlock the power of databases by writing SQL queries that extract, filter, and group information into meaningful insights. You’ll start with the basics of viewing tables, columns, and rows, then progress to combining data across multiple tables with JOINs and applying more advanced techniques like aggregate functions, subqueries, and parameterized functions. Using PostgreSQL and the free DBeaver app, you’ll gain hands-on experience exploring databases and running queries that can be applied to other SQL systems such as Microsoft SQL Server or MySQL.
SQL is one of the most valuable skills for today’s data-driven world, giving you the ability to answer questions directly from business-critical data. Whether you’re working as a Business Analyst, Data Analyst, Data Scientist, Web Developer, or in any role that touches data, mastering SQL helps you play a bigger role in making informed decisions and shaping strategy.
