Course overview
A SQL course from first queries to window functions and query tuning. Every concept is practised on business schemas sales, HR and customer data with an emphasis on writing queries that stay correct as data grows. Indexing and execution plans are introduced early enough to matter.
Learners build three databases and a set of reporting queries they can reuse at work.
Who it is for
- Analysts and MIS executives
- Developers writing queries
- Testers validating data
- Anyone moving into data roles
Prerequisites
Basic computer knowledge. No programming required.
How it runs
Learn → Practise → Build → Experience → Demonstrate, ending in a capstone. Delivered by practitioners from the engineering bench, in Madurai, Coimbatore and online.
