Firestore Mapping: Building Your Product's Neural Network ✦ No-Code DB Design #4
Hi, I'm Jian from ARCOA. 👋 In Part 1 , Part 2 , and Part 3 , we explored why database design matters, how static data builds the product's rulebook, and how dynamic data captures user behavior. Now it's time to bring both worlds to life — by mapping them into Firestore structure . Your spreadsheet is just a blueprint. Firestore is where that blueprint becomes your product's neural network. 1. Firestore Mapping: From Spreadsheet to Structure Designers naturally organize data in spreadsheets — rows, columns, simple tables. But Firestore doesn't work like Excel. It's hierarchical , not flat. To move from spreadsheet to Firestore, you need to understand the basic mapping rules — and then design relationships on top of them. ⭐ The Simplest Mapping Rules Spreadsheet Firestore Sheet collection Row document Column field Repeating values subcollection That's it. If you understand these four concepts, you can design an entire Firestore structure as a designer. 2....
