Ask your own questions of the data, get trustworthy answers, and stop waiting in the analytics queue.
Most managers and analysts live one step removed from their own data. They have a question, they file a request, they wait days for a chart, and by the time it arrives the question has moved on. Meanwhile the answer was sitting in a database that anyone with a few hours of training could have queried in minutes.
This course teaches SQL for people who make decisions rather than build software. You will not become a database engineer, and you do not need to. You will learn to read data models, write clean queries that filter, group, and join, turn raw rows into the handful of numbers a decision actually needs, and, just as importantly, recognize the pitfalls that make data lie. The teaching leans on the standard references, from Codd's relational model to Cathy Tanimura's analysis patterns, and every chapter ends with a quiz. The course ends with a timed final exam and a verifiable certificate you can put in front of an employer.
Priya Nair has spent a decade turning messy company data into decisions people actually trust, first as an analyst and then leading data teams. She is unusually good at teaching SQL to people who never expected to write a line of it, because she remembers being one of them.
