🍃 MongoDB Nima?

📖 Ta'rif

MongoDB - bu ochiq kodli, document-oriented NoSQL ma'lumotlar bazasi tizimi bo'lib, JSON-ga o'xshash hujjatlarda ma'lumotlarni saqlaydi.

✅ MongoDB Afzalliklari

Document-based - JSON format
Flexible Schema - Moslashuvchan
Scalable - Oson kengaytirish
Fast - Tez o'qish/yozish

🎯 Xususiyatlari

NoSQL - Relational emas
JSON-like - BSON format
Indexing - Tez qidirish
Aggregation - Murakkab tahlil

📚 Collections va Documents

📖 MongoDB Strukturasi

// Database yaratish va tanlash use my_blog // Collection yaratish (avtomatik) db.users.insertOne({ username: "john_doe", email: "[email protected]", profile: { firstName: "John", lastName: "Doe", age: 30 }, hobbies: ["reading", "gaming", "coding"], createdAt: new Date() }) // Document struktura { "_id": ObjectId("..."), "username": "john_doe", "email": "[email protected]", "profile": { "firstName": "John", "lastName": "Doe", "age": 30 }, "hobbies": ["reading", "gaming", "coding"], "createdAt": ISODate("2024-01-15T10:30:00Z") }

📊 Collections

users - Foydalanuvchilar
posts - Maqolalar
comments - Izohlar
categories - Kategoriyalar

📄 Documents

JSON-like - BSON format
Flexible - Turli struktura
Nested - Ichki obyektlar
Arrays - Massivlar

🔧 Asosiy Operatsiyalar

➕ CREATE - Ma'lumot Qo'shish

// Bitta hujjat qo'shish db.users.insertOne({ username: "jane_smith", email: "[email protected]", firstName: "Jane", lastName: "Smith", age: 25, isActive: true, createdAt: new Date() }) // Ko'p hujjat qo'shish db.users.insertMany([ { username: "bob_wilson", email: "[email protected]", firstName: "Bob", lastName: "Wilson", age: 35 }, { username: "alice_brown", email: "[email protected]", firstName: "Alice", lastName: "Brown", age: 28 } ])

📖 READ - Ma'lumotlarni O'qish

// Barcha hujjatlarni olish
db.users.find()

// Shartli qidirish
db.users.find({ age: { $gte: 25 } })

// Ma'lum ustunlarni olish
db.users.find({}, { username: 1, email: 1, _id: 0 })

// Bitta hujjat
db.users.findOne({ username: "john_doe" })

// Tartiblash va cheklash
db.users.find().sort({ createdAt: -1 }).limit(10)
            

✏️ UPDATE va DELETE

🔄 UPDATE Operatsiyalar

// Bitta hujjatni yangilash
db.users.updateOne(
    { username: "john_doe" },
    { $set: { age: 31, updatedAt: new Date() } }
)

// Ko'p hujjatlarni yangilash
db.users.updateMany(
    { isActive: true },
    { $set: { lastLogin: new Date() } }
)

// Ustun qo'shish
db.users.updateOne(
    { username: "john_doe" },
    { $set: { bio: "Software Developer" } }
)

// Massivga element qo'shish
db.users.updateOne(
    { username: "john_doe" },
    { $push: { hobbies: "swimming" } }
)
            

🗑️ DELETE Operatsiyalar

// Bitta hujjatni o'chirish
db.users.deleteOne({ username: "test_user" })

// Ko'p hujjatlarni o'chirish
db.users.deleteMany({ isActive: false })

// Barcha hujjatlarni o'chirish (EHTIYOT!)
db.users.deleteMany({})

// Shartli o'chirish
db.users.deleteMany({ 
    createdAt: { $lt: new Date("2024-01-01") } 
})
            

🐍 Python bilan Ulanish

📦 Kerakli Kutubxonalar

# pymongo kutubxonasini o'rnatish pip install pymongo # Yoki pip install pymongo[srv]

🔌 Ulanish va Operatsiyalar

from pymongo import MongoClient from datetime import datetime # MongoDB'ga ulanish client = MongoClient('mongodb://localhost:27017/') db = client['my_blog'] collection = db['users'] # Ma'lumot qo'shish def create_user(username, email, first_name, last_name): user_data = { 'username': username, 'email': email, 'firstName': first_name, 'lastName': last_name, 'isActive': True, 'createdAt': datetime.now() } result = collection.insert_one(user_data) print(f"Foydalanuvchi yaratildi: {result.inserted_id}") return result.inserted_id # Ma'lumotlarni o'qish def get_users(): users = collection.find() for user in users: print(f"Username: {user['username']}, Email: {user['email']}") # Ma'lumotni yangilash def update_user(username, **updates): result = collection.update_one( {'username': username}, {'$set': updates} ) print(f"{result.modified_count} ta hujjat yangilandi") # Ma'lumotni o'chirish def delete_user(username): result = collection.delete_one({'username': username}) print(f"{result.deleted_count} ta hujjat o'chirildi") # Funksiyalarni ishlatish create_user('test_user', '[email protected]', 'Test', 'User') get_users() update_user('test_user', age=25, bio='Test user') delete_user('test_user')
