Introduction

• स्वागत है मैंगो डीबी के कोर्स में जो कि सबसे बेहतरीन कोर्स होने जा रहा है
• यह सत्र MongoDB का संपूर्ण परिचय देगा और आपको इसकी विभिन्न विशेषताओं के बारे में सिखाएगा
• कोर्स को तीन भागों में बांटा गया है: बेसिक, एडवांस, और प्रोजेक्ट

Basic Topics

Introduction to MongoDB

• MongoDB एक ओपन-सोर्स, डॉक्यूमेंट-ओरिएंटेड, NoSQL डेटाबेस मैनेजमेंट सिस्टम है
• Document-Oriented NoSQL का मतलब है यह जानकारी को JSON दस्तावेज़ों के रूप में संग्रहित करता है
• यह एक बेहद फ्लेक्सिबल और परफॉर्मेंस-ओरिएंटेड सिस्टम है जो अनस्ट्रक्चर्ड और सेमी-स्ट्रक्चर्ड डेटा को संभालने के लिए डिज़ाइन किया गया है

Differences between SQL and NoSQL

• SQL: Structured, Fixed Schema, Suitable for Static Applications
• NoSQL (MongoDB): Document-Based, Dynamic Schema, Suitable for Dynamic and Evolving Data Models
• SQL Examples: MySQL, PostgreSQL
• NoSQL Examples: MongoDB, Redis

Core Operations (CRUD)

• Insert: DB.collection.insertOne(), insertMany()
• Find: DB.collection.find()
• Update: DB.collection.updateOne(), updateMany()
• Delete: DB.collection.deleteOne(), deleteMany()

Comparison Operators

• Equal, Not Equal, Greater Than, Less Than, In Operator
• Use within find queries to filter data as per condition

Aggregation Framework

• Aggregation is used for more complex data manipulations
• Consists of pipeline stages such as $match, $group, $project, etc.
• Used for operations like filtering, grouping, and transforming data

Indexes

• Used to optimize query performance
• Indexing helps in faster data retrieval and efficient sorting
• Create, delete, and manage indexes

MongoDB Atlas

• A fully managed cloud-based database service
• Allows easy deployment, management, and scaling of MongoDB clusters in the cloud
• Automated scaling options, supports global clusters
