1. MongoDB Architecture

MongoDB is a document-oriented database, which means that data is stored in JSON-like documents. Each document has a unique _id field, and documents are organized into collections.

MongoDB uses a distributed architecture, which means that data can be stored on multiple servers. This makes MongoDB scalable and fault-tolerant.

2. MongoDB CRUD Operations

The four basic CRUD operations (create, read, update, delete) can be performed on MongoDB documents using the MongoDB shell or the MongoDB driver for your programming language of choice.

3. MongoDB Querying

MongoDB provides a variety of ways to query data, including:

• Document-level queries: These queries select documents based on their _id field or on the values of their fields.
• Aggregation queries: These queries aggregate data from multiple documents into a single result.
• Geospatial queries: These queries select documents based on their location.

4. MongoDB Security

MongoDB provides a variety of security features, including:

• Authentication: This allows you to control who can access your database.
• Authorization: This allows you to control what users can do with your data.
• Encryption: This allows you to encrypt your data at rest and in transit.

5. MongoDB Administration

MongoDB can be administered using the MongoDB shell or the MongoDB administrative tools.

The MongoDB shell allows you to perform administrative tasks such as creating users, creating databases, and creating collections.

The MongoDB administrative tools provide a graphical user interface for performing administrative tasks.

6. MongoDB Applications
