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

In this lesson, we’ll learn how to export and import a MongoDB database. MongoDB provides command-line tools mongodump and mongorestore to export and import a MongoDB database, respectively. These tools are installed by default with the MongoDB Database Tools package.

## Export a MongoDB database

The **mongodump** command-line tool can export the following:
- One database
- All the databases
- Specific collection of a database


### Dump all the databases

The following command is used to dump all the databases.

```
mongodump
```

This creates a dump folder in the same directory you run the command in. The dump contains folders for each database.

If authorization is enabled, we provide a username with `mongodump`.

```
mongodump -u <username>
```

This will prompt us to enter a password. If the password is entered successfully, it dumps all the databases.

### Dump specific database

Run the below command to dump the `todo` database.

```
mongodump -d "todo"
```

If authorization is enabled, we provide a username with `mongodump`.

```
mongodump -u <username> -d "todo"
```

This will prompt us to enter a password. If the password is entered successfully, it dumps the `todo` database.

### Dump specific database collection

Run the below command to dump the `tasks` collections of the `todo` database.
```
mongodump -d "todo" -c "tasks"
```
