Hands-On SQL: Solve Real Business Problems with Data
Happy Monday!
Think about learning a new language—you can study grammar and vocabulary all day, but real progress happens when you actually start speaking. Data analytics is no different. Taking a course on SQL or data visualization is valuable, but the real learning happens when you work on projects. Every challenge forces you to think critically, troubleshoot issues, and develop a deeper understanding of what’s going on. That’s exactly where the real growth happens.
Types of Analytics
The best way to get comfortable with data analytics is by doing. No matter the domain—HR, Sales, Manufacturing, or any other field—you can apply different types of analysis to uncover insights. Here are some key types of analytics and the SQL techniques to master them:
Changes Over Time Analysis – Spot trends and track growth using DATEPART(), DATETRUNC(), and SUM().
Cumulative Analysis – Calculate running totals and moving averages with SUM() OVER() and AVG() OVER().
Performance Analysis – Use LAG(), AVG() OVER(), and CASE to measure trends and compare performance.
Data Segmentation – Organize data into meaningful categories with CASE and GROUP BY.
Part-to-Whole Analysis – Compare different metrics using SUM(), AVG(), and SUM() OVER().
The key takeaway? Theory is great, but real mastery comes from practice. So dive into projects, experiment with real-world data, and start uncovering insights today!
