BeginnerSQLAnalyticsBeginner

What it means

SQL is a set of simple words used to ask a database a question.

Why it matters

It gives you one reliable building block for doing Data Analytics work correctly and explaining it to someone else.

Tiny example

Imagine a analytics task as a small recipe. SQL is one named step in that recipe, with a clear input and result.

Remember this

Say it simply: “I use SQL to move from a question to a checked result.”
