Definition
Google's NoSQL cloud database that syncs data in real-time and scales automatically — the primary database used by 404Fault.
قاعدة البيانات السحابية NoSQL من Google التي تُزامن البيانات في الوقت الفعلي وتتوسع تلقائياً — قاعدة البيانات الأساسية التي يستخدمها 404Fault.
Why It Matters
Firestore is the database tier of the 404Fault stack. Understanding its document model, security rules, compound queries, and counter patterns is essential for building any feature on the platform.
Firestore هي طبقة قاعدة البيانات في مجموعة 404Fault. فهم نموذج مستنداتها وقواعد الأمان والاستعلامات المركبة وأنماط العدّادات ضروري لبناء أي ميزة على المنصة.

Example Usage
“Firestore path: `glossary/{termId}`. Document fields: `{ id: 'GLS-000001', slug: 'large-language-model', nameEn: 'Large Language Model', status: 'published', viewCount: 0 }`. To query published AI terms: `db.collection('glossary').where('status', '==', 'published').where('category', '==', 'ai-ml').limit(50).get()`.”
“مسار Firestore: `glossary/{termId}`. حقول المستند: `{ id: 'GLS-000001', slug: 'large-language-model', nameEn: 'نموذج لغوي كبير', status: 'published', viewCount: 0 }`. للاستعلام عن مصطلحات AI المنشورة: `db.collection('glossary').where('status', '==', 'published').where('category', '==', 'ai-ml').limit(50).get()`.”
AI Builder Tips
Avoid these mistakes when using Firestore:
Using Firestore for relational queries — Firestore does not support JOIN; denormalize or restructure your data model
Not indexing compound queries — any query with multiple `where()` clauses requires a composite index or it throws at runtime
Using document IDs as sequential integers — Firestore ID sharding works best with random IDs; sequential IDs cause hotspotting
