📌 الـ NoSQL - قواعد بيانات غير علائقية (Non-Relational Databases)
- ملهاش جداول ثابتة زي SQL، بتستخدم طرق تخزين مختلفة زي المستندات (Documents)، الـ (Key-Value)، الـ (Wide-Column)، أو الرسوم البيانية (Graph).
- مش بتحتاج مخطط ثابت (Schema-less)، يعني ممكن تخزن بيانات غير متناسقة بدون مشاكل.
- مناسبة للبيانات اللي بتتغير باستمرار والأنظمة اللي بتحتاج سرعة عالية وقابلية توسع كبيرة، زي مواقع التواصل الاجتماعي وأنظمة التحليل الفوري.
- أمثلة عليها: MongoDB (بتستخدم الـ Documents)، Redis (بتستخدم Key-Value)، Cassandra (بتستخدم Wide-Column).

في MongoDB، لو عندك مجموعة (Collection) اسمها Users، وعاوز تجيب المستخدمين اللي أعمارهم فوق 25 سنة، هتستخدم استعلام زي ده:
db.Users.find({ "age": { $gt: 25 } })

أستخدم أي نوع في المشروع؟ 🤔
✅ الـ SQL مناسب لو عندك بيانات مترابطة وعاوز تضمن التكامل بينها.
✅ الـ NoSQL مناسب لو عندك بيانات غير منظمة، أو بتحتاج تتوسع بسرعة، أو عندك عمليات قراءة وكتابة ضخمة.Build Distributed Systems from ScratchLearn distributed systems the hard way, by implementing real algorithms.
