MongoDB vs PostgreSQL

MongoDB and PostgreSQL are the two most standard databases that are used for the enterprise application. Even though both the databases are open-source, and they have several differences.

In this section, we are going to discuss the differences between MongoDB and PostgreSQL database system based on various aspects.

What is MongoDB?

It is a document-oriented, cross-platform, open-source database and written in C++ programming language. It is used to deliver a high volume of data storage, rich query language, high performance, and high availability.

The primary objective of using this database is that it is easy to use and to understand big-data support, fast development features, and flexible deployment. MongoDB is established and maintained by a 10gen company, which is known as MongoDB Inc. The developers can easily understand and use it, and the data is stored in a JSON-like format.

It is developed to work on the collection and document concepts. It is a cross platform, which means that it supports various Operating Systems such as Linux, Windows, MacOS, etc. with different programming languages like Java, Node.js, C, PHP, C++, Python, and Ruby.

What is PostgreSQL?

PostgreSQL is the most popular Object-Relational Database Management System used to manage the relational database and securely store it. It is an open-source database software and written in C programming language.

PostgreSQL follows the transaction along with the ACID (Atomicity, Consistency, Isolation, and Durability) properties. It supports various operating systems such as Microsoft Windows, UNIX, Mac OS X, LINUX, and so on.

It is the initial database that provides the multi-version concurrency control (MVCC) feature.

Let us see some of the essential differences between MongoDB and PostgreSQL, which will help us to enhance our knowledge:
