This flexibility is a huge benefit for avoiding bottlenecks and delays resulting from asking a DBA to restructure data definition language statements, before recreating and reloading a relational database . For instance, MQL enables users to reference data from numerous tables, transform it, aggregate it, and filter results for greater precision — like SQL. And unlike SQL, MQL functions in a way that’s idiomatic for every programming language.

MongoDB and PostgreSQL Database Technologies

Thanks to the document model’s emergent properties, development and collaboration are both simpler and quicker. MongoDB’s immense flexibility is fantastic for gathering information from a variety of sources or for accommodating document variations across a period of time. This is particularly valuable with the ongoing deployment of new application functionality. Of course, it may take some time to understand which database is ideal for you, especially if you’ve never encountered either option before. We’ve written this article to offer greater insight into each database’s characteristics so you can make an informed choice and end up with the perfect solution.

Step 1-a: Launch MongoDB

That’s easier to do if you are working on a new application, or plan on modernizing an existing one. Schema validation enables you to apply governance and data quality controls to your schema. If you are a SQL shop and introducing MongoDB vs PostgreSQL a new paradigm will cost more than any other benefits mentioned will offset, PostgreSQL is a choice that will likely meet all your needs. In MongoDB, if any new column is added then it is referred to as a field in the document.

Launch a MongoDB database on Clever Cloud, and then how to add some test data to it. You should now be able to view the replicated data using standard SQL commands. Note that you must change the search_path according to the DB Name that you specified when you set up the PostgreSQL destination in Airbyte.

Having a database to collect customer information, such as likes, dislikes, order history, or articles read, allows a business or organization to target their consumers more readily. This will lead to higher sales, more traffic, and better targeted ads. There are several different flavors of normalization, but the high level explanation is that it reduces redundancy and anomalies in your data. The retail store example from above could have certainly used a computerized database to increase productivity and reduce the amount of manual tabulating.

Architecture/Document Model

Realized in proprietary language PL/pgSQL or with common languages like Perl, Python, Tcl etc. MongoDB on a Plesk server can only be installed inside the Docker container. For more information on how to install MongoDB on a Plesk server, you can have a look here. You might be required to divert resources to find new solutions for scaling through caching or denormalizing data, or by employing alternative strategies. MongoDB and PostgreSQL’s developer communities are typically ready to assist when needed. Below, we’ll explore how SQL and MongoDB approach querying data, with a few helpful examples.

  • Imagine we have two separate people who are using an ATM to each retrieve cash from the same account at the same time.
  • Developers can choose what’s essential in the application and make database alterations as required.
  • PostgreSQL stores data as Structured objects rather than documents.
  • For instance, MQL enables users to reference data from numerous tables, transform it, aggregate it, and filter results for greater precision — like SQL.

While both PostgreSQL and MongoDB make amazing databases, it ultimately comes down to choosing what’s right for your business. MongoDB Atlas performs the same way across the three biggest cloud providers, making migration between multiple clouds easier. Furthermore, PostgreSQL provides data encryption and allows you to use SSL certificates when your data transits through the web or public network highways. PostgreSQL also enables you to implement the client certificate authentication tools as an option, and use cryptogenic functions to store encrypted data in PostgreSQL. However, MongoDB does have other options like the enterprise and Atlas , which have varying prices.

Features of MongoDB:

MongoDB Atlas has a globally aware, multi-cloud platform ready for you, which you completely manage yourself. Certain other databases have emulated PostgreSQL’s approach to linking APIs from languages to its databases. This simplifies moving a program running PostgreSQL to another SQL database . As PostgreSQL depends on a scale-up strategy for scaling writes or data volumes, it has to take full advantage of the computing resources made available to it. PostgreSQL achieves this via multiple indexing and concurrency strategies. This standard of engineering is beyond that of many commercial databases — they typically don’t bother with it as it can be incredibly difficult to achieve with decent performance.

An on-premise pricing model is offered for the MongoDB enterprise edition. Unlike MongoDB, PostgreSQL depends on a scale-up strategy for data volumes and scaling writes. It’s performed by adding more hardware resources like disks, CPUs, and memory to an existing database node. Assessing the performance of two different database systems is challenging since both MongoDB and PostgreSQL have different ways of storing and retrieving the data. However, the denormalization process usually causes high memory consumption when previously normalized data in a database is grouped to increase performance.

MQL too offers similar features as SQL with some additional capabilities. This is done because documents are processed as JSON-type documents. Using a drag-and-drop-based interface, permits users with zero coding experience to build data pipelines and effectively clean and transfer high-volume data sets. This entire process doesn’t require complicated code, so you can move data to the database of your choice without any data engineering experience.

Validate data replication pipelines with data-diff

But MongoDB might be a poor fit if you have a large number of incumbent apps based on regional data models and teams that have experience with SQL only. MongoDB is especially capable of handling data structures that have been created by modern apps and APIs. It’s perfectly positioned to offer support for the agile, ever-changing development cycle seen in organizations today. Every MongoDB shard is run as a replica set — a synchronized cluster consisting of three or more servers that keep replicating data between them.

MongoDB and PostgreSQL Database Technologies

One of the few that actually uses MongoDB for their main service is Foursquare, and that came back to bite them with days of downtime which would not have occurred if they were using a RDBMS. The current data engineering solutions that businesses require for data and query processing necessitate a steep learning curve, which PostgreSQL lacks. PostgreSQL doubles the storage capacity of databases that need to be upgraded. DbVisualizer is equipping database professionals with the tools they need to build, manage and maintain state-of-the-art database technologies. It has sky-high user satisfaction and is the preferred tool for database professionals around the world.

You dumped a decades-tested, fully featured RDBMS for a young, beta-quality, feature-thin document store with little community support. Unless you’re already running tens of thousands of dollars a month in servers and think MongoDB was a better fit for the nature of your data, you probably wasted a lot of time for negative benefit. MongoDB is fun to toy with, and I’ve built a few apps using it myself for that reason, but it’s almost never a better choice than Postgres/MySQL/SQL Server/etc. Both databases support syntax that is quite different from one another.

Foreign Key Support

On top of this, MongoDB offers support for various programming languages. Idiomatic drivers are available for more than a dozen languages, but the MongoDB community has contributed plenty of others. You can take advantage of real-time aggregation, ad-hoc queries, and rich indexing to give powerful programmatic ways to access and examine data of all structure types.

MongoDB: The Scalable Document Database That Has Become a Data Platform

Unlike SQL, MQL works in a way that is idiomatic for each programming language. Essentially, it’s simpler for document databases to implement transactions as they keep data clustered in a document, and no multi-document transaction is required as document reading is an atomic process. One field or more might be written in just one operation, including updates to numerous sub documents and array elements.

Both Databases Are Awesome, But What Is Your Need?

When starting a new project, one of the things developers can struggle with is choosing a stack. Zeroing in on the right technology to solve a problem can be a nerve-wracking experience. Databases in particular can be challenging to settle on, especially if you’re unclear about how your data will be used. MongoDB uses BSON, a binary JavaScript Object Notation, under the hood to make querying extremely fast. The BSON is translated to JSON to be read when you open your collection.

MongoDB vs. PostgreSQL: What Is MongoDB?

MongoDB has only recently started to support ACID transactions similar to SQL databases. For MongoDB, this is achieved by using a “replica set” — a synchronized cluster consisting of three or more servers that keep replicating data between them. This provides redundancy and protection against any downtime that might occur in the event of a scheduled break for maintenance or a system failure, thus increasing the fault tolerance of the database.

Both these technologies are leveraged by organizations of all scales, both big & small, and depending on the situation, one can dominate over the other. They help you to resolve queries with greater efficiency by making the data simpler and thereby easier to scan. Both databases use different syntax and terminology to perform many of the same tasks. Where PostgreSQL uses rows to record data, MongoDB uses documents, etc. They also have many features that distinguish them from one another. The nature of your data and your target use cases are also vitally important.

Clever Cloud – hosting of the MongoDB and PostgreSQL databases. In this section, we are going to discuss the differences between MongoDB and PostgreSQL database system based on various aspects. Some young developer at the company likes to keep up with the latest-and-greatest trends, read all the NoSQL noise in past months and got excited, so decided to try it out in some new project. Even to this date, I feel more comfortable working with PostgreSQL than MongoDB.

This means that there could be times where the database is not reliable, but over time it will reach consistency. So your data is basically in a fluid state until it becomes consistent. Hevo Data, a No-code Data Pipeline helps to load data from any data source such as Databases, SaaS applications, Cloud Storage, SDK,s, and Streaming Services and simplifies the ETL process. Hevo not only loads the data onto the desired Data Warehouse but also enriches the data and transforms it into an analysis-ready form without having to write a single line of code.

MongoDB Atlas runs in the same way across all three major cloud providers, simplifying migration and multi-cloud deployment. If you want a relational database that will run complex SQL queries and work with lots of existing applications based on a tabular, relational data model, PostgreSQL will do the job. MongoDB generally stores the data like documents and represented in a binary form which is called binary JSON.
