What is MongoDB? Interesting Facts to know in 2023

One of the software that helps companies develop modern Web-based apps is MongoDB. Organizations of various sizes and shapes are looking to harness the potential of data to discover new business opportunities and enhance existing business processes. Organizations that effectively use data have an advantage in making quicker and better-educated business decisions. However, working with wrong information can pose a challenge for both functions and businesses, particularly in software development and data management.

One of the most important areas where organizations require speedy development of phases and effective data management is the creation of advanced web-based software. Organizations require a top-quality operating system that can be implemented in the shortest time possible. Furthermore, the applications are required to be scalable. Therefore, all applications must be built and designed on a suitable database for the task. In the past, web applications utilized relational databases as their primary data storage, with an appreciation of the well-normalized data model. However, as web applications evolve and evolve, developers are increasingly switching to alternative data stores, for instance, NoSQL (Not only Structured Query Language), due to their advantages.

This database lets organizations develop scalable, data-driven applications. The models for data and persistence are designed for maximum read and write speeds. Furthermore, it includes the ability to automatically failover. If you’re interested in knowing what MongoDB is, its advantages and how MongoDB can help run modern web-based applications, This blog is ideal for you.

What is MongoDB?

It is a NoSQL database management program. NoSQL database systems can replace traditional databases that use SQL (Structured SQL Query Language). Information is saved in rows, tables and columns of a relational database. The database has connections between entities. In this, the data is saved in documents with a JSON-like structure to display and interact with data.

The Benefits of MongoDB

It offers a variety of advantages. Its benefits include:

  • NoSQL databases are more affordable and easier to maintain. NoSQL databases offer features like easy data distribution, simplified data models, and automated repair. These advantages result in lower administrative expenses and, consequently, cost less.
  • Open-source means it is free and requires fewer charges for servers. Open-source is completely free. NoSQL databases utilize lower-cost servers, and the cost of data processing and storage per gig is considerably lower.
  • It’s extremely easy to use and highly adaptable. Because NoSQL databases such as MongoDB are horizontally scalable, they can scale by adding devices to your pool of resources.
  • It can be integrated with caching. System memory caching improves the speed of data output.
  • MongoDB is free of schema problems. It is possible to store data in the NoSQL database without the need to use a predefined schema, which means you can alter the model of data and format without affecting applications.
  • It’s user-friendly. MongoDB provides various helpful options (Ad-hoc query, aggregate limited collection and file storage, indexing load balancing, replication and Server-side JavaScript execution) that make it a user-friendly database.

6 Key Features of MongoDB

The primary characteristics of MongoDB are:

  1. Document-oriented model

MongoDB was developed to meet the flexible and productive minds of developers. One way to achieve this is to make it document-oriented. The document model permits data to be saved as documents, which are then grouped into collections. Documents are self-contained, making it simple for developers to concentrate on one particular data set without splitting it across tables.

MongoDB also employs the BSON format to keep documents. BSON is an encoded binary JSON format capable of storing videos, images, and text. It is simple to interact via a MongoDB driver specific to the programming language used.

  1. Replication

In other databases, particularly relational ones, there’s always the issue of losing data. If data is stored in a server, it is a source of failure. The server might be damaged, the hardware might fail, and the internet service could be disrupted. Many other similar situations could make it difficult for users to access their data.

With MongoDB replication, it is possible to avoid issues with data loss by transferring data across several servers. These servers can be used for scaling up databases, data recovery, and backups. Replication is also the possibility for the storage engine in databases to distribute the load of reading over the different replications.

In a set comprising replica sets, only one primary server, or”node”, is one that can accept all writing applications. If the primary server fails, the system will select another of these servers to become the primary node in the timeframe.

  1. Balance of load

The proper balance of the load is crucial to managing databases in large-scale companies. Because the number of client requests and user traffic is in the thousands and millions each day, they have to be divided across different servers to increase efficiency and decrease overcrowding. MongoDB handles both write and read requests by balancing the loads across its servers while ensuring data consistency. This means that using MongoDB is not a requirement for any additional load balancers.

  1. Schema-less database

MongoDB is a database that does not have schemas, meaning it could comprise various kinds of documents within a single collection. This is in stark opposition to the conventional databases with an established schema structure, ensuring that similar data is stored in rows within the table.

MongoDB One collection may include documents of various dimensions, fields, and different types of contents. This creates a flexible schema for databases. Developers take advantage of this flexibility since data can easily be moved between schemas without interrupting or altering existing data. Additionally, MongoDB also can enable an adaptable schema to be fixed. If needed, you can also implement validation policies for the collections.

  1. Sharding

Sharing refers to sharing huge amounts of data and spreading it over many machines or units called shards. Sharding can be extremely beneficial to databases when it can handle complicated and complex queries. This is the case for websites with millions of users who log in or use this platform daily. In MongoDB, Sharding can also lead to easier horizontal scaling. The addition of more shards provides the possibility for spreading data out, which in turn, helps to increase the size of the database.

Each shard is a piece of the dataset which is the entirety and serves as a database which can better manage many requests with no downtime. In a sharding-based environment, the queries are routed to various shards by using a key for shards. This process of handling is known as Mongos. If done correctly, it will result in a more efficient load balance.

  1. Indexing

In MongoDB, every document field is indexed using primary and secondary indexes. This helps reduce the time to search for data in the database. The database engine uses the index to filter out data rather than search each document one after another for specific entries. The indexing feature of MongoDB is among the top features because it cuts down time spent finding answers to queries.

MongoDB Examples

MongoDB is a database with admirers, and here are a few instances of businesses or organizations using MongoDB as a database.

  • Aadhar: The Indian Unique Identification project is the largest biometric database in the world. Its Aadhar Project uses MongoDB to keep the huge biometric and demographic data of more than 1.2 billion Indians. Aadhar also utilizes MongoDB to store images of its projects.
  • eBay: The most well-known online auction site utilizes MongoDB to manage projects like cloud management and metadata storage, search suggestions, and merchandise classification.
  • Shutterfly: The most well-known online photo-sharing service boasts more than 6 billion photos and a speed that can reach 10,000 operations per second. Shutterfly has moved from Oracle to MongoDB to find MongoDB more suitable to its needs.
