SQL Project: Understanding HAVING vs WHERE with Real Business Data

This project focuses on one of the most commonly misunderstood SQL concepts: HAVING vs WHERE.
Using two realistic datasets — an employees table (HR use case) and an orders table (e-commerce use case) — the project demonstrates how to correctly filter data before and after aggregation.

The goal is to help learners clearly understand:

When to use WHERE (row-level filtering)

When to use HAVING (group-level filtering)

How GROUP BY works with aggregate functions
