<h2>Introduction to the course</h2><p>MongoDB is a popular open-source NoSQL database that is designed for storing and retrieving large amounts of data efficiently. It is based on the concept of a document-oriented database, which means that data is stored as JSON-like documents with optional schemas.</p><h2>Who is this course for?</h2><p>MongoDB is designed for developers who need a flexible and scalable database for storing and managing large amounts of data. It is often used in applications that require real-time analytics or the ability to store and retrieve large amounts of data quickly and efficiently.</p>

MongoDB

<h2>What does this lesson cover?</h2><p>MongoDB is a database program, in this lesson we will be defining the term database program before transitioning to MongoDB.</p><p>We will thus discuss key features and terms of MongoDB and put our knowledge to use with lesson quizzes.</p>

Introduction

<h2>What does this lesson cover?</h2><p>Installing MongoDB is a simple process that does not require prerequisites and can be accomplished smoothly and fast.</p><p>This lesson covers the installation process of MongoDB across all Operation Systems.</p>

Installation

<h2>What does this lesson cover?</h2><p>Before getting into MongoDB queries, we will be identifying the broad term that is query.</p><p>Queries offer a way to fetch, add, delete and manipulate data in your database. </p><p>It is used in all database programs and its complexity will be uncovered in this lesson.</p>

Queries

Lesson Challenge

<h2>What does this lesson cover?</h2><p>In this lesson, we will be focusing on the MongoDB method that deletes a single document in your collection.</p><p>The method will be displayed and defined in code to help developers better understand the works of the function and its structure. Finally, through the help of lesson quizzes, we will put our knowledge to use and conclude the lesson.</p>

Delete document

<h2>What does this lesson cover?</h2><p>Update Operators are used to change the values of already existing fields or add new ones. There&#x27;s a long list of update operators in MongoDB, we will start off easy with the set operator before moving onto that list.</p><p>Each operator will be provided with its syntax and structure in code with standard examples and supporting lesson quizzes.</p>

Update Operators

<h2>What does this lesson cover?</h2><p>The find() method is used to fetch documents by querying them. </p><p>In this lesson we will be covering the basic syntax of the method, the arguments it takes on and its more complex and standard use in MongoDB.</p>

Find

<h2>What does this lesson cover?</h2><p>A collection is a group of MongoDB documents. We will be learning how to create a collection in MongoDB with the createCollection() method. Thus, we will put our newly gained knowledge to use with lesson quizzes.</p><p>Now that we have the basics down, we will talk about the different types of collections and how to incorporate them into our program.</p>

Creating Collection

<h2>What does this lesson cover?</h2><p>In this lesson, we will be covering how to delete multiple documents in your collection.</p><p>The method will be displayed and defined in code to help developers better understand the works of the function and its structure. Finally, through the help of lesson quizzes, we will put our knowledge to use and conclude both the lesson and section altogether.</p>

Batch delete

<h2>What does this lesson cover?</h2><p>Updating documents in a collection can be executed with the two different methods given in the lesson.</p><p>There are a few rules to follow when using these simple yet crucial functions.</p><p>We will guide you through updating documents with lesson quizzes and code examples.</p>

Document update

<h2>What does this lesson cover?</h2><p>Create operations are a part of CRUD, which stands for create, read, update, and delete. It is a set of operations that are commonly used in database systems</p><p>Create Operations in MongoDB indicate inputting information in a collection. </p>

Create Operations

<h2>What does this lesson cover?</h2><p>Query Operators are used to compare document fields.</p><p>In this lesson, we will be talking about the three separate types of query operators: Comparing, Logical, and Evaluation.</p><p>Finally, we will put our knowledge to use with the help of lesson quizzes.</p>

Query Operators

<h2>What does this lesson cover?</h2><p>The validator option helps developers specify certain validation rules and regulations (a single validation rule or multiple validation rules)for documents in a given collection.</p><p>This lesson covers how exactly validation rules work and their limitations.</p>

Validation

<h2>What does this lesson cover?</h2><p>Indexes are data structures that hold a mapping of keys to documents. Although this textbook definition might seem difficult, this lesson helps uncover the indexing and discusses the most common types of indexing: the Unique Index and the Compound Index.</p>

Indexing

Installing MongoDB

<p><strong>Installing MongoDB </strong>on your system requires the following short list of steps that need no prerequisites whatsoever.</p><p></p>

<p>First off, you&#x27;ll need to download the MongoDB Community Server from the official MongoDB website. Pay attention to the version you install, it should correspond with your operating system.</p>

<p>All that&#x27;s left is for you to follow the instructions according to your OS. </p><p></p>

<p>On <strong>Windows</strong>, this will involve running the downloaded <strong><slot>.msi </slot></strong>file and following the prompts in the installation wizard. On <strong>macOS </strong>and <strong>Linux</strong>, you will need to extract the downloaded<strong><slot> .tgz</slot></strong> file and then run the installation script.</p>

Further Steps

<p>Once the installation is complete, you can start the MongoDB server by running the <strong>mongod </strong>command in your terminal.</p>

<p>To interact with the MongoDB server, you will need to use the <strong>mongo shell</strong>, which should have been installed as part of the MongoDB package. You can start the <strong>mongo shell</strong> by running the mongo command in your terminal.</p>

Write Missing

<p>Start the MongoDB server after installation.</p>

<h2>What does this section cover?</h2><p>MongoDB is used in a wide range of applications, including large-scale data management, and content management. It is popular among developers because it is easy to set up and use, and it is highly scalable and flexible. This section gives newbies a sneak peek into the key terms of MongoDB and how it works under the hood.</p>

Get Started

<h2>What does this section cover?</h2><p>This section covers two important topics. Firstly, we&#x27;ll talk about how to create collections in MongoDB  To finish the lesson off, we will discuss the different types of collections.</p><p>Finally, to conclude the section, we will refer to CRUD, specifically The Create Operation.</p>

Create

<h2>What does this section cover?</h2><p>We will be getting into the find method, query operators, and indexing. But what do all these areas have in common?</p><p>They are all a part of the set of Read Operations in CRUD.</p><p>The find method, query operators, and indexing in MongoDB will be extensively covered in separate lessons with lesson quizzes and code examples as a guide.</p>

Read

<h2>What does this section cover?</h2><p>Update Query Operators will be the focus of this section. We will be discussing the types of Update Operators, Document Update, and lastly, Validation.</p><p>We will start off easy with the fundamental set operator and transition into other update operators before moving to document updating and validators in MongoDB.</p>

Update

<h2>What does this section cover?</h2><p>Last but not least, we have CRUD&#x27;s Delete Operation that helps delete documents in your database program, in our case, MongoDB.</p><p>In this section, we will be discussing the different methods in use for removing documents: specifically deleting only one, or multiple documents.</p>
