Introduction

Welcome to the MongoDB Shell Commands Workbook for Bookstore Inventory & Customer Sales Management.
This workbook is designed to guide you through the process of
creating a MongoDB database,
adding, removing, deleting, and modifying data records using MongoDB shell commands.
Our theme for this workbook is a bookstore. We will be tracking inventory and customer sales.

Prerequisites

Before we begin, make sure you have the following installed on your system:
MongoDB: Download and install the latest version of MongoDB from
https://www.mongodb.com/try/download/community
⁠
.
A text editor: Any text editor like VSCode, Sublime Text, or Atom will work.

Setting up a MongoDB Database
⁠
To start the MongoDB server, open a command prompt or terminal and run the following command:
Study the documentation for mongod here:
⁠
https://www.npmjs.com/package/mongod
⁠
⁠
npm install mongod
mongod

Open another command prompt or terminal and run the following command to start the MongoDB shell:
Copy code
mongo

To create a database for the bookstore, run the following command in the MongoDB shell:
perlCopy code
use bookstore

Inserting Inventory Data
⁠
First, let's create a collection called 'inventory'. To insert a new book into the inventory, use the following command:
db.inventory.insertOne({
title: "The Catcher in the Rye",
author: "J.D. Salinger",
isbn: "9780316769174",
price: 9.99,
stock: 10
});

Querying Inventory Data
⁠
To query all books in the inventory, use the following command:
luaCopy code
db.inventory.find();

To find a specific book by ISBN, use the following command (replace '9780316769174' with the ISBN you want to search for):
cssCopy code
db.inventory.findOne({isbn: "9780316769174"});

Updating Inventory Data
⁠
To update the stock of a book in the inventory, use the following command (replace '9780316769174' with the ISBN of the book you want to update, and '5' with the new stock value):
cssCopy code
db.inventory.updateOne({isbn: "9780316769174"}, {$set: {stock: 5}});

Deleting Inventory Data
⁠
To remove a book from the inventory, use the following command (replace '9780316769174' with the ISBN of the book you want to remove):
cssCopy code
db.inventory.deleteOne({isbn: "9780316769174"});

Inserting Customer Sales Data
⁠
First, create a collection called 'sales'. To insert a new customer sale, use the following command:
yamlCopy code
db.sales.insertOne({
customerId: 1,
purchaseDate: new Date(),
items: [
{
isbn: "9780316769174",
quantity: 1
}
],
totalPrice: 9.99
});

Querying Customer Sales Data
⁠
To query all customer sales, use the following command:

db.sales.find();

To find sales by a specific customer, use the following command (replace '1' with the customer ID you want to search for):
cssCopy code
db.sales.find({customerId: 1});

Updating Customer Sales Data

Updating Customer Sales Data
⁠
To update a customer's sale record, first, find the sale by its _id. For example, if the _id is ObjectId("1234567890abcdef12345678"), use the following command to update the totalPrice to a new value (replace '20.99' with the new total price value):

db.sales.updateOne({_id: ObjectId("1234567890abcdef12345678")}, {$set: {totalPrice: 20.99}});

To update the quantity of a book in a customer's sale record, use the following command (replace '9780316769174' with the ISBN of the book you want to update, and '2' with the new quantity value):

db.sales.updateOne(
{"items.isbn": "9780316769174"},
{$set: {"items.$.quantity": 2}}
);

Deleting Customer Sales Data
⁠
To remove a customer's sale record, first, find the sale by its _id. For example, if the _id is ObjectId("1234567890abcdef12345678"), use the following command to remove the sale:

db.sales.deleteOne({_id: ObjectId("1234567890abcdef12345678")});
