Managing Big Data with MySQL

Korshub take

Offered by Duke University, this course introduces relational databases through the lens business analysts actually need: using SQL and MySQL to answer real business questions. 193,337 students have taken it as a practical, non-theoretical entry point into working with structured data at scale.

You'll learn database design and data-modeling fundamentals, then apply query languages directly to business-analysis problems — the kind of hands-on SQL practice that separates knowing what a database is from being able to actually pull the numbers a business needs. Big data concepts are introduced alongside, connecting classroom SQL to real-world scale.

Who it's for

• Business analysts who need to query data directly instead of waiting on a data team
• Aspiring data analysts building core SQL and database-design skills
• Anyone curious how relational databases actually organize business data

A solid, practical foundation for anyone whose job increasingly runs through a database rather than a spreadsheet.
