Firestore Data Modeling

What problem does it solve?

This skill addresses the challenge of structuring Firestore data to maximize security, scalability, and query performance for user-owned data such as bills, accounts, templates, and settings.

Core Features & Use Cases

• User-scoped collections to ensure data isolation and clean security rules
• Denormalization strategies to optimize read performance and reduce joins
• Security-first design with rules that enforce per-user access and data integrity
• Query patterns for common tasks like fetching unpaid bills, balances, and templates

Quick Start

Define a Firestore model for a user-scoped billing app with collections at users/{userId}/bills, accounts/{accountId}, templates/{templateId}, and settings/{preferences}. Provide example security rules and sample queries to retrieve unpaid bills, recent activity, and account balances.
