Welcome to module 9, aggregate functions.

This module explores the built-in aggregate functions for summarizing and analyzing data in SQL queries.

You'll learn how to use aggregate functions such as SUM, AVG, COUNT, MIN, and MAX to perform calculations on groups of rows, extract valuable nuggets, and generate quality reports that your users will love.

Through hands-on examples and interactive demos, we'll explore various scenarios where aggregate functions lead, from simple calculations to complex data analysis tasks.

Each lesson includes a homework assignment to reinforce your learning, and you'll have access to all example code in the Grumpy Old IT Guy GitHub repository. Join us to master aggregate functions and level up your SQL skills!

We will demonstrate different use cases and scenarios requiring aggregate functions through illustrative examples and interactive demos.

As usual, each lesson includes several examples and demos, plus a homework assignment to reinforce your learning.

All example code is available at the end of the course outline.
