Most beginners picture a database as some mysterious thing hiding inside their app. It’s not. It’s a real, openable, inspectable collection of tables that you can browse like a spreadsheet. Once you see one for yourself, it stops being intimidating and starts being a debugging superpower.
In this lesson we’ll cover the small vocabulary you need, introduce TablePlus as the tool for actually looking inside a database, and install the single most valuable debugging instinct you can have as a builder.
- The basic vocabulary: tables, rows, and columns
- How to use TablePlus to open and explore any database
- Why your app has separate local and production databases
- The “just go look at the data” instinct that saves hours of debugging
