Top 15 MongoDB Alternatives And Competitors


August 10, 2021

As the globe grapples to deal with heaps of structured and unstructured data collected by them, the smart way to manage this bulk of data and extract the insightful information out of it is through big data solutions and database services. One popular name in the world of big data technologies is MongoDB.

MongoDB has been a popular open-source database management system that leverages a document-oriented database model. Released in the year 2009, as a non-relational database and NoSQL database program, MongoDB has been utilized for big data applications, supporting various forms of data. It uses collections and documents, instead of tables and rows. It is written in C++ and has been considered ideal for mobile apps, real-time analytics, IoT-based applications, etc. MongoDB has been figuring as one of the most wanted database skills among software developers worldwide as of 2021.

Some of the key features of MongoDB include effective storage of data, ad-hoc queries for optimized and real-time analytics, high insert rate for cases with a high write load, appropriate indexing for good query executions, replication for improved data accessibility and stability, sharding and load balancing.

Even with its salient features and growing community, there are certain areas where it lacks – high data consumption due to denormalization, lack of functions to bind logic, not ACID-compliant, etc. Even though NoSQL has the best of database features, there are certain areas that are not taken care of, which is why developers are trying to search for other alternatives.

Through this article, we are attempting to lay down a few popular alternatives and competitors of MongoDB that can fulfill your requirements.
