PostgreSQL vs MySQL vs MongoDB Features and Benefits Comparison

If you are leaning toward making ACID a priority, research should be done to investigate if transactions are performed in an acceptable manner for your product. NoSQL databases don’t usually conform to the ACID properties but instead adopt eventual consistency. This makes NoSQL databases less ideal for financial institutions where the validity of its transactions is most important.

Any errors will trigger the update operation to roll back, reverting the change and ensuring that clients receive a consistent view of the document. PostgreSQL is a rock solid, open source, enterprise-grade SQL database that has been expanding its capabilities for 30 years. Everything you would ever want from a relational database is present in PostgreSQL, which relies on a scale-up architecture. If your concerns are compatibility, serving up thousands of queries from hundreds of tables, taking advantage of existing SQL skills, and pushing SQL to the limit, PostgreSQL will do an awesome job. PostgreSQL uses FDW to retrieve the data from other systems as it can change into any form of a data source. It helps the generally written queries in SQL can be used to fetch the data from the data source like table and others.

MongoDB is a non-relational database, while PostgreSQL is a relational database. While NoSQL databases work on storing data in key-value pairs as one record, relational databases store data on different tables. PostgreSQL is a highly stable database management system, backed by over 20 years of community development that has led to its high levels of integrity, resilience, and correctness. You can use PostgreSQL as the primary data warehouse or data source for various mobile, geospatial, analytics, and web applications. There are other benefits of using when choosing between MongoDB vs. PostgreSQL. The platform has a unique pricing model that charges you for the number of connectors you use and not the data you consume.

  • PostgreSQL may be a smart relative dB that additionally offers a number of the advantages of a document model.
  • It is likely that you can easily find help to make your SQL database project in general and PostgreSQL project in particular work.
  • In MongoDB, if any new column is added then it is referred to as a field in the document.
  • We begin in Section 2 with MongoDB support for joins, then continue in Section 3 with the corresponding capabilities in Postgres.
  • MongoDB is flexible and allows its users to create schema, databases, tables, etc.
  • Furthermore, partial and advanced indexing techniques such as GiST, KNN Gist, SP-Gist, GIN, BRIN, covering indexes, and bloom filters can also be implemented in PostgreSQL.

It basically means there is no need for you to mention their structure. Obviously, there are a lot of documents in a collection and in case the need to add a novel filed is felt, it can be done without affecting any other document. Also, there is no need to take the system offline and updating the system catalog. » moreNavicat for PostgreSQL is an easy-to-use graphical tool for PostgreSQL database development. MongoDB additionally helps you to increase your write outturn by deferring writing to disk.

Document databases can do JOINs, but they are done differently from multi-page SQL statements that are sometimes required and often automatically generated by BI tools. That said, MongoDB does have a SQL connector that allows SQL access, mostly from BI tools. MongoDB Atlas has also been extended through MongoDB Realm to ease app development, through Atlas Search powered by Lucene, and with features that support data lakes built on cloud object storage. The plumbing that makes MongoDB scalable is based on the idea of intelligently partitioning data across instances in the cluster. MongoDB does not break documents apart; documents are independent units which makes it easier to distribute them across multiple servers while preserving data locality.

Support & Community

We also have experts, and you can hire PostgreSQL developers easily. Dr. Stonebraker has been a pioneer of database research and technology for more than forty years. He was the main architect of the INGRES relational DBMS, and the object-relational DBMS, POSTGRES. These prototypes were developed at the University of California at Berkeley where Stonebraker was a Pro …

MongoDB vs PostgreSQL

Lots of data management and BI tools rely on SQL and programatically generate complex SQL statements to get just the right collection of data from the database. PostgreSQL does very well in such contexts because it is a robust, enterprise-grade implementation that is understood by many developers. PostgreSQL calls itself an open source object-relational database system. MongoDB has seen massive adoption and is the most popular modern database, and based on a Stackoverflow developer survey, the database developers most want to use. Thanks to the efforts of MongoDB engineering and the community, we have built out a complete platform to serve the needs of developers.

The important thing to remember is that transactions allow many changes to a database to be made in a group or rolled back in a group. MongoDB maintains the documentation, which helps is defining the servers. The database is free of cost and belongs to the traditional database concept that we call ORDBMS (Object-Relational Database Management System).

It supports a wide range of procedures and functions which MongoDB or MySQL does not support. The main difference between a relational database such as PostgreSQL and a document-oriented database such as MongoDB is that you don’t need to know the structure of data in the latter option. You can collect and store data without any planning or table design. With relational databases, you need to design the table around the data structure, and any data that doesn’t fit the design can’t be stored. A relational database will reject data that doesn’t adhere to column design rules. Using JSON allows you to change your schema on a whim without repercussion.

MongoDB vs PostgreSQL

In MongoDB, Collection is used for storing the related information. In PostgreSQL, the tables are used for storing the related data information. Further, the database has its free as well as enterprise version.


Relational databases are great at running complex queries and data-based reporting in cases where the data structure doesn’t change frequently. Open-source databases like PostgreSQL offer a cost-effective alternative as a stable production-grade database compared to its licensed contemporaries like SQL Server and Oracle. Since these constraints disallow any actions that remove links from one table to another and can stop the insertion of invalid data into foreign key columns, this may be a necessary feature for some users. MongoDB is a schema-free NoSQL database that supports a distributed architecture. MongoDB uses collections to enforce different rules and triggers to maintain the relationship between different attributes in the database.

MongoDB is also getting popular as it getting used with new technologies like ReactJS etc. Further, it is open-source, and that is why it became the developer’s choice. Also, at Linearloop we have a PostgreSQL database server to develop projects without any hurdles.

However, the programmer must know that the department field refers to a document in the department collection. In other words, there is no notion of foreign keys to assist the programmer in specifying the join. First, department information is repeated for each employee in the department. Since Bill and Fred are both in the Shoe department, information will be replicated.

There might be other information too but that can be stored in other tables. It is equipped with one of the best features and i.e. eliminating the repeated content or data. RDBMS is an acronym that stands for Relational Database Management System. It’s MongoDB vs PostgreSQL usually a SQL-based database such as PostgreSQL or MySQL and meets the ACID requirement. We call it “relational” because the values in a table and tables themselves are related, making it possible to run queries across many tables at the same time.


Furthermore, you can also review various groups or users’ data access activities with the auditing option which grants an extra layer of security. However, PostgreSQL is not as fast as MongoDB, as it’s a relational database that stores data in rows and columns. MongoDB can be a good choice if you want your database to be highly scalable and have a high computation & processing power. It can also be used if users lack programming skills as it is very easy to learn and does not follow the traditional SQL syntax. PostgreSQL can be a better choice if you have fewer resources but are well-versed in the traditional SQL syntax and procedures.

It needs several teams in development, ops, and the database administrator to coordinate the changes made in the structure carefully. However, PostgreSQL has made some efforts towards performance optimizations, including a mature query planner, just-in-time compilation of expressions, table partitioning, and parallelization of read queries. MongoDB has only recently started to support ACID transactions similar to SQL databases.

MongoDB has the potential for ACID compliance, while Postgres has ACID compliance built-in. ACID are principles or components that work towards data validity, especially in databases intended for transactional workflows. comes with out-of-the-box connectors for both MongoDB vs. PostgreSQL, helping you move data to the database of your choice without breaking a sweat. The most recent version of PostgreSQL has new features such as improved performance for queries and performance gains and space savings when B-tree index entries become duplicated. Companies like Groupon, Trivago, and Revolt use PostgreSQL to manage data. MongoDB offers both community support, tutorials, and, for a price, full training and upgrading under the supervision of a support engineer.

When to use PostgreSQL

On the other side, PostgreSQL also has several features but not as many as in the case of MongoDB. Navicat for MongoDB gives you a highly effective GUI interface for MongoDB database management, administration and development. In mongoDB, we don’t have to define the schema to handle data that follows any structure. So in a use case where you have to save unstructured data, then mongoDB is the best database to fulfill your requirement. MongoDB and PostgreSQL are both different types of databases, and both serve different purposes.

Comparing MongoDB vs PostgreSQL

Image SourceMongoDB also offers an On-Premise pricing model with MongoDB Enterprise Advanced edition. It has a monolithic architecture where all the components work together in an automated manner. It has an automatic load configuration feature to group similar data in its database. In the modern world today, competition between companies is very common, especially when they are offering similar products. In the competitive field of Data Analytics, offering efficient products and services and having a majority customer share in the market does help determine the profit of the company.

PostgreSQL: A Modern SQL Database

It was developed at the University of California, Berkeley, and was first released on 8th July 1996. Instead of storing data like documents, PostgreSQL stores it as Structured objects. BSON allows for certain data types that are not used with regular JSON, such as long, floating-point, and date. MQL too offers similar features as SQL with some additional capabilities.


Not simply in terms of storage, however additionally in terms of what you would like to try and do together with your data. Postgres doesn’t supply any native mechanisms to scale the info on the far side one server or to produce always-on info handiness. AI is a wide field of technology that’s used to create intelligent machines, while… Realized in proprietary language PL/pgSQL or with common languages like Perl, Python, Tcl etc.
