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

# Insert single record

To create a `todo` application, we insert a task into the MongoDB collection. We can assign any name to the collection, but it should be relative to the data stored in that collection. Here, we’ll choose `tasks`.

We can use the below command to choose a database.


```
use todo;
```

Below is the syntax to insert a single document.

```
db.<collection name>.insertOne(Document, Options);
```

The `Document` argument is an object that specifies properties in the `<key>:<value>` pattern.

Below is the property of the `Options` argument of the `insertOne` command.

**`writeConcern`**

The example below demonstrates how to insert a task into the `tasks` collection.

Learn and practice inserting single and multiple documents into a collection.
