Certificate SQL Engineering Beginner to Advanced.pdf

This course built my technical foundation in SQL for handling structured data environments. I practiced writing advanced queries involving joins, subqueries, aggregations, and data transformation techniques. It improved my ability to extract clean, structured insights from large datasets efficiently.

Beyond syntax, I learned how SQL supports real analytics workflows from data extraction to preparing datasets for reporting and dashboards. The hands-on practice strengthened my confidence in working with databases and enabled me to support analytics and operational reporting functions effectively.
