MongoDB Tutorial

This is the introductory lesson of the MongoDB tutorial, which is part of the ‘MongoDB for Developers’ course. This tutorial will give you an overview of the course, its prerequisites, and the value it will offer to you.

What is MongoDB?

MongoDB is an open source document-based database that allows embedded documents, arrays, and represents a complex hierarchical relationship using a single record. MongoDB is touted to be better than relational data models as it allows people to sort unstructured data with ease.

Let us explore the benefits of MongoDB to professionals and organizations in the next section.

Benefits of MongoDB to Professionals and Organizations

MongoDB is beneficial for professionals who administer, manage, analyze large and complex data, such as database administrators, data analysts, and System and enterprise architects.

The MongoDB tutorial is designed to help professionals in:

  • Schema design

  • Developing Web application in Java and Node JS

  • Developing Mobile application in Java and Node JS

MongoDB allows database developers to perform the following tasks:

  • Schema design

  • Optimize performance

  • Manage security, availability, and consistency

  • Monitor and manage clusters

MongoDB allows Data Analysts to

  • Perform CRUD operations and

  • Analyze the data stored in MongoDB

System and Enterprise Architects can perform the following tasks using MongoDB’s unique features:

  • Analyze Use cases

  • Design system architecture

  • Scale Read and write functions and

  • Optimize query performance

In the next section of the MongoDB Tutorial for beginners, we will talk about NoSQL databases and RDBMS and how they differ.

Difference between MongoDB and RDBMS

MongoDB is a type of NoSQL document oriented database. NoSQL databases are different from Relationship Database Management Systems (RDBMS) in the sense that NoSQLs are easier to work with and can be adapted to different forms of data storage. As a result, NoSQL databases are more in demand than RDBMS.

Take a look at the table given below to understand the difference between the two databases.




Data storage:

Multiple Storage Formats - Comprises of different databases with different data storage models

Single Storage Format - Data is stored in a tabular format with numerous rows and columns

Schemas and Flexibility:

Dynamic Schema - You can add columns anytime. The databases can be adapted to meet changing needs.

Fixed Schema - All fields are predefined before data-entry. To change the structure of these fields will be difficult.


Horizontal scaling - This database can be scaled across multiple servers. This method of scaling is cost effective.

Vertical scaling - This database scaling needs bigger servers and therefore costs more.

Atomicity, Consistency, Isolation, Durability (ACID) Compliancy:

Relational databases are mostly ACID compliant.

Most NoSQL databases compromise ACID compliancy for performance and scalability.

Next, let’s talk about the prerequisities for the MongoDB administrator tutorial. 

MongoDB Tutorial Prerequisites

The basic prerequisite needed to learn MongoDB is a fundamental knowledge of programming language and Hadoop components. However, participants are expected to have a knowledge of SQL commands.

Let us explore the MongoDB Tutorial Overview in the next section.

MongoDB Tutorial Overview

This MongoDB tutorial will provide a detailed introduction of MongoDB and its features. This course will include:

  • The difference between NoSQL and the traditional Relational Database Management System or RDBMS databases.

  • A detailed introduction of MongoDB as a document database

  • An explanation of MongoDB’s role in the Big Data Ecosystem, as well as, database scaling, replication, and sharding.

  • Information on how CRUD operations in MongoDB are performed and the process of developing Java and Node JS applications.

  • Detailed steps for installing MongoDB in different operating systems and performing various functions

In the next section, we will discuss the objectives of the MongoDB tutorial.

Objectives of the MongoDB Tutorial

By the end of the MongoDB tutorial, you will be able to:

  • Explain the functionalities of MongoDB as a document database
  • Identify the benefits of MongoDB
  • Explain the different use cases of MongoDB
  • Explain how to create and manage different types of indexes in MongoDB for query execution
  • Explain how the replication and sharding features in MongoDB help in scaling read and write operations
  • Explain the process of developing Java and Node JS applications using MongoDB
