MongoDB is an open-source NoSQL database and stores data in the form of documents. It can be used as an alternative to traditional relational databases. NoSQL databases are schema-less and useful for working with large sets of distributed data. 

In this course, you will learn the core concepts of MongoDB including queries, documents, embedded documents, and operators with advanced features like CRUD operations, bulk write operations, GridFS, indexing, aggregation pipeline, authorization, and more.

You will have plenty of hands-on experience with the help of interactive widgets, and by the end you will have a strong understanding of how to build MongoDB-based applications.

MongoDB: The Complete Guide

## Prerequisites

Below is a list of prerequisites to install the MongoDB on macOS:

1. **Xcode Command Line Tools:**
Use the below command to install Xcode command-line tools. Run the below command in your macOS terminal.
   ```
   xcode-select --install
   ```
2. **Homebrew:**
Follow these instructions to install Homebrew.

## Install MongoDB community edition
Follow the below steps to install the MongoDB community edition:

1. Tap the MongoDB Homebrew to download the official Homebrew formula for MongoDB and the Database Tools. Run the below command in your macOS terminal.

   ```   
    brew tap mongodb/brew
   ```

2. Install MongoDB. Run the below command in the macOS terminal.
   ```
   brew install mongodb-community@5.0
   ```

   This command will show downloading progress. Once that is completed, we’ll be able to check whether MongoDB is installed or not.

Type the below command in your macOS terminal to check whether MongoDB is successfully installed or not.

```
mongod --version
```

This command will return the MongoDB version installed on your system.

Run the below command in your macOS terminal to start the MongoDB Service.

```
brew services start mongodb-community@5.0
```
After running the above command you will see a message "Successfully started `mongodb-community`." Enter “mongo” on the terminal to check access to the shell. Then, type “exit” to exit from the shell.

Next, we run the below command in our macOS terminal to stop the MongoDB Service.

```
brew services stop mongodb-community@5.0
```

# Install on Linux (Ubuntu)

Different commands are used to install MongoDB on different Linux systems. In this lesson, we’re only demonstrating how to install MongoDB on Ubuntu. Follow the instructions [here](https://docs.mongodb.com/manual/installation/) to install it on some other Linux OS.


1. Import the public key used by the package management system.
   ```
   wget -qO - https://www.mongodb.org/static/pgp/server- 5.0.asc | sudo apt-key add -
   ```
2. Create a list file for MongoDB.
Ubuntu 20.04 (Focal)
   ```
   echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
   ```
   Ubuntu 18.04 (Bionic)
   ```
   echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
   ```
   Ubuntu 16.04 (Xenial)
   ```
   echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
   ```
3. Reload local package database.
   ```
   sudo apt-get update
   ```
4. Install the MongoDB packages.
