Ask any hiring manager: SQL is the most demanded skill in data analyst job postings, and MySQL is the most common place to practise it. Analysis starts where the data lives — in the database.
Key Points
- Company data lives in databases — analysts query the source directly
- GROUP BY + aggregates replicate pivot tables at any scale
- JOINs combine customers, orders, and products into full business pictures
- Window functions unlock trends, rankings, and running totals
- Repeatable SQL beats manual spreadsheet steps for weekly reporting
- Every BI tool (Power BI, Tableau, Looker) speaks SQL underneath
