BSON data types overview in MongoDB - Mini Project: Build & Apply

BSON Data Types Overview

📖 Scenario: You are working with a MongoDB database for a small online bookstore. You want to organize the book information using different BSON data types to store various kinds of data correctly.

🎯 Goal: Build a MongoDB document that uses different BSON data types to represent book details such as title, price, availability, publication date, and tags.

📋 What You'll Learn

Create a document with fields using these BSON data types: String, Double, Boolean, Date, Array, ObjectId

Use exact field names: _id, title, price, inStock, publishedDate, tags

Assign the specified values exactly as described in each step

💡 Why This Matters

🌍 Real World

Using correct BSON data types in MongoDB documents helps store and retrieve data efficiently in real-world applications like online stores, blogs, and social networks.

💼 Career

Understanding BSON types is essential for database developers and administrators working with MongoDB to design schemas and optimize queries.

1

Create the basic book document with _id and title

Create a MongoDB document called book with the field _id set to ObjectId("507f1f77bcf86cd799439011") and the field title set to the string "Learn MongoDB".

MongoDB

# Create the book document with _id and title
# Your code here

Need a hint?

Use ObjectId() to set the _id field and a string for the title.

2

Add price as a Double and inStock as a Boolean

Add the field price with the value 29.99 as a Double and the field inStock with the value true as a Boolean to the book document.

MongoDB

book = {
    "_id": ObjectId("507f1f77bcf86cd799439011"),
    "title": "Learn MongoDB"
}
# Add price and inStock fields below
# Your code here

Need a hint?

Use a number with decimals for price and true for inStock.

3

Add publishedDate as a Date

Add the field publishedDate with the value ISODate("2023-01-15T00:00:00Z") to the book document.

MongoDB

book = {
    "_id": ObjectId("507f1f77bcf86cd799439011"),
    "title": "Learn MongoDB",
    "price": 29.99,
    "inStock": true
}
# Add publishedDate field below
# Your code here

Need a hint?

Use ISODate() to set the date in ISO format.

4

Add tags as an Array of Strings

Add the field tags with the array value ["database", "mongodb", "nosql"] to the book document.

MongoDB

book = {
    "_id": ObjectId("507f1f77bcf86cd799439011"),
    "title": "Learn MongoDB",
    "price": 29.99,
    "inStock": true,
    "publishedDate": ISODate("2023-01-15T00:00:00Z")
}
# Add tags array below
# Your code here

Need a hint?

Use square brackets [] to create an array of strings.
