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

# Collation

Collation is used when we need to specify language-specific rules for string comparison. The collation can be specified for any collection or operation that supports collation.

Syntax:
```
{
  "locale": <string> // Required
}
```

A collation can be used with:
1. A collection
2. A view
3. An index
4. A specific operation like `insertOne` or `updateOne`.

Below is an example to use collation for an index.
```
db.tasks.createIndex({ 
    name: 1 
}, { 
    collation: { 
        locale: "fr"
    }
})
```
