in this i have taughed about the mongodb

1. Introduction to
MongoDB
MongoDB is a popular open-source NoSQL database that uses a
document-oriented data model. It provides high performance, high
availability, and easy scalability. MongoDB eliminates the need for an
Object-Relational Mapping (ORM), making it easier for developers to
store and access data.

2. What is MongoDB?
1 Scalability
MongoDB allows
horizontal scaling
through sharding, which
distributes data across
multiple machines.
2 Flexibility
It supports various data
types and provides
dynamic schema design,
making it especially
useful for agile
development.
3 Performance
With in-memory
computing and native
JSON support,
MongoDB offers fast
read and write
operations.

3. Advantages of using MongoDB
Document Storage
Stores data in flexible, JSON-like documents
which can vary in structure, offering a more
natural representation of data.
Scalability
Easily scales out to handle larger amounts of
data and high throughput.

4. Introduction to Mongoose
1 Object Modeling
Mongoose provides a straightforward,
schema-based solution to model
application data.
2 Validation
It supports built-in data validation, ensuring
data integrity and consistency.

5. What is Mongoose?
Data Modeling
Mongoose allows for easy definition of
schemas and models for MongoDB
collections.
Middleware Support
Enables custom and predefined
operations before or after certain
events.

6. How to connect MongoDB with Node.js
using Mongoose
Install Mongoose
Use npm to install Mongoose
package for Node.js.
Setup Connection
Establish a connection
between Node.js and
MongoDB using Mongoose.
CRUD Operations
Perform create, read,
update, and delete
operations using Mongoose
with MongoDB.

7. Basics of Node.js
10K
Community
Node.js has a large and active community
providing extensive support and resources.

Event-Driven Architecture
Node.js utilizes an event-driven, non-blocking I/O
model, making it lightweight and efficient.

8. Introduction to Node.js
Environment Node.js provides an environment for executing
JavaScript code on the server-side.
Libraries It offers a rich repository of libraries to extend
its functionality and features.

9. Setting up a Node.js project
1 Initialize Project
Use npm init command to create the initial project structure.
2 Install Dependencies
Use npm to install necessary packages such as express and mongoose.
3 Create Server
Write code to create a server using Node.js and set up the routes.

10. Basics of querying MongoDB using
Mongoose
1 Find() Method
Use Mongoose's find() method to
query data based on specific
conditions.
2 Update() Method
Modify existing data in MongoDB
using Mongoose's update() method.
