It's lap 24 of the Marrow Bay Grand Prix and the pit wall's screens are dark. You're the data engineer: every SQL query you write lights up a panel, from the driver roster to live timing, pace charts, the timing tower and finally the call to box a car.
Each lesson adds one working part to your build.
Chapter 1
Read the database: pick columns, filter and search rows, sort them, remove repeats.
Chapter 2
Summarise thousands of seconds into a few numbers, handle missing values, then connect the tables.
Chapter 3
Turn data into decisions, then write to the database.
