Definition

A powerful open-source relational database that stores data in tables with rows and columns.

قاعدة بيانات علائقية مفتوحة المصدر قوية تخزّن البيانات في جداول بصفوف وأعمدة.

Why It Matters

PostgreSQL powers Supabase. Understanding SQL and relational databases helps when choosing between Firestore and Supabase for a project.

PostgreSQL يُشغِّل Supabase. فهم SQL وقواعد البيانات العلائقية يساعد عند الاختيار بين Firestore وSupabase لمشروع ما.

Full Definition

PostgreSQL is one of the most popular relational databases. It organizes data into tables with a fixed schema, uses SQL to query data, and enforces relationships between tables with foreign keys. Supabase is built on PostgreSQL. Unlike Firestore (NoSQL, schemaless), PostgreSQL requires you to define your schema upfront with migrations.
PostgreSQL هي إحدى أكثر قواعد البيانات العلائقية شيوعًا. تُنظِّم البيانات في جداول ذات مخطط ثابت وتستخدم SQL للاستعلام عن البيانات وتُطبِّق العلاقات بين الجداول باستخدام مفاتيح خارجية. Supabase مبني على PostgreSQL. على عكس Firestore (NoSQL بدون مخطط)، يتطلب PostgreSQL تعريف مخططك مسبقًا باستخدام الترحيلات.

Example Usage

“SELECT * FROM projects WHERE status = 'published' ORDER BY created_at DESC LIMIT 12; is the SQL equivalent of a Firestore query.”

“SELECT * FROM projects WHERE status = 'published' ORDER BY created_at DESC LIMIT 12; هو مكافئ SQL لاستعلام Firestore.”
