NoSQL, which means ‘not only SQL,’ is an approach to Database Management that suits several Data Models, including document, columnar, graph formats, and key-value. A NoSQL database is a Data Storage and Retrieval Mechanism modeled in ways other than the traditional table structures utilized in Relational Databases.

NoSQL Databases are compatible with several data models for storing and accessing data. These types of databases have become more famous in the era of Big Data and high volume web, Cloud, and mobile applications, although they have been around for a while now. Most NoSQL databases are scalable across different data centers. They also run as distributed systems, enabling them to perform better with Cloud Computing Infrastructure.

What is MongoDB?

MongoDB is a Distributed Architecture and an Open-source NoSQL Database Management Program with the essential function to create highly accessible and adaptable web-based technologies. MongoDB tool is widespread among database development players because it offers an incredibly flexible schema. In addition, MongoDB, which provides drivers for all scripting languages, enables users to create their app without wasting time setting up a database. It also offers other advantages over traditional RDBMS. 

Key Features of MongoDB

MongoDB offers a world of advantages to companies needing a reliable database. Here are some benefits of using MongoDB:

  • Speed: MongoDB is 100 times faster than the average Relational Database. As a document-oriented database, MongoDB makes accessing documents easy by indexing. This facilitates quick query response, which saves users valuable time.
  • Sharding: Another advantage benefit MongoDB provides is that it allows users to store extensive data. This is done by distributing the data to several servers connected to the application. If one server can’t handle the size of the data, it is shared to another server through a process called auto-sharding.
  • Flexible Database: MongoDB allows users have different types of data in a separate document because it is a schema-less database. This affords its users high flexibility and the freedom to store data of any kind.
  • Horizontal Scalability: MongoDB is a horizontally scalable database, which is one of its essential advantages. It allows users to distribute large amounts of data to several machines efficiently.
  • Transaction Feasibility: Some MongoDB features include gridFS and Replication. These features support an increase in Data Availability while using MongoDB. This ensures that the applications’ performance is very high.
  • Absence Of Schemas: MongoDB is NoSQL, meaning it does not require schemas. Therefore, it’s unnecessary to outline your database schemas when using MongoDB. This cuts down the amount of time your database takes to process information. Thus, your schema will be defined by the algorithm you code.

Limitations of MongoDB

As much as MongoDB offers significant advantages over other databases, it is not perfect. It has some limitations that need to be worked on. Here are some of the disadvantages of MongoDB. 

  • Joins Not Supported: Unlike rational databases that support joins, MongoDB doesn’t. Although joins functionality can be added by coding it manually, it may be slow to execute and affect performance.
  • High Memory Usage: MongoDB is designed to store key names for every value pair. It is also affected by data redundancy because it lacks the functionality of joins. This results in high memory usage.
  • Limited Data Size: The maximum document size allowed with MongoDB is 16MB. This is a serious challenge that needs to be rectified.
  • Limited Nesting: MongoDB offers limited nesting access, as users can’t perform more than 100 levels of nesting of documents.

Real-life Examples Of MongoDB Use Cases

You have looked at some of the MongoDB use cases, so now let’s discuss a few real-life applications of this database system. Here are a few real-life applications Of MongoDB By Some Prominent Companies.

1) India’s Aadhaar

Aadhaar is a fantastic example of a real-world MongoDB use case. Aadhaar is India’s Unique Identification Project and the world’s most extensive Biometrics Database System. The program launched in 2009 has collected demographic and biometric information from over 1.2 billion people. Aadhaar relied on MongoDB, among other database systems like HBase, MySQL, and Hadoop, to store this massive amount of data. However, MongoDB was one of the database systems first purchased to power the search strategy.

2) Forbes

Another real-world MongoDB use case is Forbes. When a story becomes viral, people resort to every available website to get details. Therefore, it is essential for publishers to be alert and give shareable information as soon as possible to keep their readers informed.

This prompted Forbes to find practical solutions to boost its Content Engagement Rate. Forbes constructed its CMS and mobile application in two months using MongoDB. They had to redesign their website and switch to MongoDB to upload content from anywhere in the world efficiently.

Their editors also took advantage of MongoDB’s flexible structure to deliver dynamic quality material promptly to their viewers. This brave action eventually paid off. With this, they could eliminate poor existing practices while lowering overhead expenses.

3) MetLife

MetLife is a market leader in employee insurance, benefit plans, and pensions. They serve over 90 million clients across the Middle East, Europe, Asia, Latin America, Japan, and the United States. MetLife’s sophisticated customer service solution, “The Wall,” is built on MongoDB.

The Wall is a tool that offers a consolidated view of MetLife Customers’ payments, policy statements, and other information. It functions like Facebook’s Wall, which gathers data from 70 historical systems and integrates it into a database table. The Wall has a capacity of 24 TB and is distributed across six different servers in two Data Management Centers. Currently, MetLife is looking to further improve its service with several Big Data initiatives, including MongoDB-based apps.

Many retail businesses need Real-time Analytics. This requires that their apps remain relevant and always available online, with no interruption. This is because slow response time leads to a lot of revenue loss in the retail industry due to the cutthroat competition.

When consumers have several alternatives, they will not hesitate to switch to a more reliable service provider. For example, Otto is a major e-commerce company with a massive user base looking to meet and exceed its customers’ expectations. However, prompt response time was a significant challenge because their website has over 500 companies.

Otto is a classic MongoDB use case where they used MongoDB to lower their response time to between 1 to 2 seconds to solve this problem. They had to rebuild their entire catalog application. They used MongoDB because of its customizable schema capabilities, reliability, and growth characteristics.

5) Shutterfly

Shutterfly is a major Digital Picture Exchange and Private Publishing Firm with over 6 billion photographs and a processing volume of up to 10,000 calculations every second. It is one of the businesses that switched from Oracle to MongoDB.

During their transition to MongoDB, it became clear that running non-Relational Databases would better meet the company’s data demands, potentially enhancing programmer efficiency and customizability.

Before choosing MongoDB, Shutterfly investigated several other database systems, including BerkeleyDB and Cassandra. However, the firm settled for MongoDB while implementing it to data relevant to uploaded photographs. Still, the conventional RDBMS remains in place for aspects of the process that require a fuller transactional architecture, such as payment and account administration.

Shutterfly is pleased with its choice to adopt MongoDB, as noted by its data architect, Kenny Gorman, who said the firm believes in picking the right technology for the task. His statement showed that MongoDB was an excellent match, although not without tradeoffs. For example, many issues cropped up before they streamlined their services to match their users’ needs.


Major gaming firms like FACEIT and SEGA have effectively used MongoDB to improve their consumers’ interactive experiences. Underneath the shell, FACEIT relies on MongoDB as its primary Database System. In addition, MongoDB manages the orchestration of services between gamers, groups, and contests.

FACEIT even uses MongoDB to maintain its User Profile and Tournament Data. Users’ live streaming data is saved in MongoDB, and other metrics are used to measure players’ activity and interaction. Due to MongoDB’s Flexible Structure and Extensive Query Model, FACEIT could keep user profiles more effectively.

7) Weather Channel

While running its website,, the Weather Channel had problems servicing a massive clientele because it used a standard RDBMS system. However, MongoDB enabled them to develop their Smartphone application that serves over 40 million active users and provides Real-time Meteorological Data to its clients.

They also employed MongoDB’s Scalable Solution and MapReduce Functionalities to perform Real-time Analytics and forecasts based on weather data obtained. The prototype version that had previously taken weeks to develop was delivered in just a few hours. This gave The Weather Channel an edge over the competition.
