Summary of "Complete MongoDB Tutorial #6 - Adding New Documents"

In this tutorial, the speaker demonstrates how to add new documents to a MongoDB database using both the MongoDB shell and MongoDB Compass. The focus is on inserting documents into a collection called "books" within a database named "bookstore."

Main Ideas and Concepts:

Tools Used:
- MongoDB Shell: Command-line interface for interacting with MongoDB.
- MongoDB Compass: GUI tool for visualizing and managing MongoDB data.
Switching Databases:
The speaker shows how to switch from the default "test" database to the "bookstore" database using the command:
```
use bookstore
```
Referencing a Collection:
To insert documents, you must reference the appropriate collection using:
```
db.books
```
Inserting a Single Document:
The method insertOne is used to add a single document to a collection. The document is passed as an object with properties such as title, author, pages, genres, and rating.

Example command:
```
db.books.insertOne({
    title: "The Color of Magic",
    author: "Terry Pratchett",
    pages: 300,
    rating: 7,
    genres: ["fantasy", "magic"]
});
```
Automatic ID Assignment:
MongoDB automatically generates a unique ID for each document upon insertion.
Inserting a Document into a Non-Existing Collection:
The speaker illustrates that you can insert a document into a collection that does not yet exist, and MongoDB will create the collection automatically.

Inserting Multiple Documents:

The insertMany method allows for inserting multiple documents at once. An array of objects is passed to this method.

Example command:

db.books.insertMany([
    { title: "The Light Fantastic", author: "Terry Pratchett", pages: 250, rating: 8, genres: ["fantasy"] },
    { title: "Dune", author: "Frank Herbert", pages: 412, rating: 9, genres: ["science fiction"] }
]);

Verification of Document Insertion:
After inserting documents, users can refresh their MongoDB Compass interface to see the updated collection with the new documents.
Deleting a Collection:
The speaker briefly shows how to delete a collection using the command:
```
db.authors.drop();
```

Methodology/Instructions:

To Switch to a Database:
Use the command: use <database_name>
To Reference a Collection:
Use: db.<collection_name>
To Insert a Single Document:
Use: db.<collection_name>.insertOne({<document_object>})
To Insert Multiple Documents:
Use: db.<collection_name>.insertMany([<array_of_document_objects>])
To Delete a Collection:
Use: db.<collection_name>.drop()
