01 / Our mission
Make the underlying
logic make sense.
A database is more than a place to store information. It is a way to describe relationships, ask precise questions, and make deliberate decisions about data.
Our mission is to explain those ideas in a structured written format, with examples you can read closely, revisit, and work through at your own pace.
