These “data dictionaries” appear to the user as tables, but they do have information stored internally by the database system. The real question isn’t MongoDB vs PostgreSQL, but rather the best document database vs the best relational database. Altering a table after onset can be done, but can lead to not easily identifiable bugs down the road. The basic idea behind atomicity is that it supports a transaction paradigm. Either a transaction fails completely or succeeds completely, such as a transfer on funds from one account to another. Its completely automated pipeline offers data to be delivered in real-time without any loss from source to destination.
Choosing the right tech to solve a problem can be a harrowing experience. Databases in particular can be a bit tough if we’re unsure how our data is going to be used. It will help simplify the ETL and management process of both the data sources and destinations. MongoDB finds it very hard to integrate data from multiple sources and store that data in a common format. MongoDB has the potential for being ACID Compliant whereas PostgreSQL has it built-in. The ACID properties are the fundamental properties of databases so that transactions can be tracked properly.
The database selection depends on the platform and the environment as well. 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. Stand-alone NoSQL technologies do not meet ACID standards because they sacrifice critical data protections in favor of high throughput performance for unstructured applications. It’s not hard to apply ACID on NoSQL databases but it would make database slow and inflexible up to some extent. “Most of the NoSQL limitations were optimized in the newer versions and releases which have overcome its previous limitations up to a great extent”.
Both PostgreSQL and MongoDB are supported in all the major Operating Systems, including Windows, Linux, Unix, etc. Additionally, as there’s no support for joins, MongoDB databases are oversupplied with data — sometimes duplicate — hence heavily burdening the memory. There are other benefits of using Integrate.io when choosing between MongoDB vs. PostgreSQL.
Open-source data integration
To sum up, so far, we’ve covered the basic details of PostgreSQL and MongoDB alike. We’ve discussed their history, key features, and what makes them different. While PostgreSQL uses the GROUP_BY function to process and run aggregate queries MongoDB typically uses aggregation pipelines to process its queries. PostgreSQL, while not as fast as MongoDB in terms of its raw insertion speed, excels in terms of ACID compliance. Transactions are processed safely and reliably, allowing an entire transaction to fail instead of executing a write that partially succeeded.
It also provides you a brief overview of both databases along with their features. Finally, it highlights a few challenges you might face when you use these databases. Read along how you can choose the right database for your organization. Using Integrate.io, your company can optimize data integration tasks and use your existing database solution to its full potential without knowing complicated code like Python and Java.
One of the most powerful features of relational databases that make writing applications easier is ACID transactions. The details of how ACID transactions are defined and implemented fill many computer science text books. Much of the discussion in the computer science realm is about isolation levels in database transactions.
MongoDB vs PostgreSQL: Pricing Models
Data collection and analysis is key for any business to survive in this big data era. How you want to access and use data will help you choose the database that will most suit your data and client needs. One of the things that we may struggle with as developers when working on a green field project is our stack.
MongoDB is a database system that processes data using BSON, whereas PostgreSQL is a relational database that processes data using traditional SQL. PostgreSQL supports a wide range of data types, document types, and customizations, to name a few. Plenty of BI and data management tools depend on SQL and create complex SQL statements to gather the right assortment of data from the database. PostgreSQL performs brilliantly in situations like these, as it’s a strong, enterprise-grade implementation that most developers understand. SQL’s advantages include a huge tool ecosystem, programming languages designed to use SQL databases, and integrations. You’ll probably be able to find assistance to make your general SQL project work properly, and for your specific PostgreSQL project too.
MongoDB can deal with both normalized and denormalized data models . On the other hand, PostgreSQL supports declarative partitioning, which is essentially a way to specify how to divide a table into partitions. The table that is divided is called the partitioned table, the specification consists of the partitioning method, and the list of columns or expressions to be used is called the partition key. Since version 5.0, MongoDB has included a “live” resharding feature that comes as a major time-saver since you only need to set a policy. The database can automatically redistribute the data when the time comes. Data can be distributed across different regions with ease via the MongoDB Atlas cloud service.
Query Language Map
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. PostgreSQL has a wide range of connected interfaces, which helps in supporting the other programming languages. 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.
The scale-out strategy relies on using a larger number of smaller and usually inexpensive machines. In a relational database, the data in question would be modeled across separate parent-child tables in a tabular schema. This means that updating all the records at once would require a transaction. MongoDB vs PostgreSQL benchmark both are different database management system.
Features of MongoDB:
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. Foreign keys allow us to keep our data normalized by referencing an object from one table in another so the second table has access to the first table’s keys and values. RDBMS is an acronym that stands for Relational Database Management System. It’s 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.
- The PostgreSQL syntax to insert a record into the table is shown below.
- If you prioritize faster data integration and scalability across several servers, MongoDB might be a suitable choice for your business.
- MongoDB does have the possibility to be ACID compliant, whereas PostgreSQL already is.
- NoSQL databases are generally simpler by nature, so MongoDB is relatively easy to learn for those with any prior programming experience.
For load balancing and accessibility, MongoDB also claims to support the JSON data model, auto-sharding, and built-in replication. PostgreSQL users have to be prepared for the difficulties of scalability when an application is launched. PostgreSQL utilizes a scale-up strategy, so at one time or another in high-performance use cases, it’s possible to hit a wall.
No-code Data Pipeline For your Database
Now in the document database world of MongoDB, the structure of the data doesn’t have to be planned up front in the database and it is much easier to change. Developers can decide what’s needed in the application and change it in the database accordingly. Moreover, I am using Ruby on Rails 3, and an ODM called Mongoid.
BSON boasts data types that are unavailable in JSON data, such as int, datetime, decimal128, and more. It provides type-strict handling for a variety of numeric types, rather than a universal “number” type. When you want to introduce a new field to a document, you can do so without disrupting those other documents within the collection. There’s no need to update an ORM or a central system catalog, and you don’t have to take the system offline. You may also use schema validation to put data governance controls into effect for all collections. On the other hand, PostgreSQL is a perfect match for data analysis and warehousing.
As any fundamental technology like a database grows, it is supported by a platform ecosystem of services, integrations, partners, and related products. At the center of the MongoDB platform ecosystem is the database, but it has many layers that provide additional value and solve problems. So use cases that require super speedy queries and massive amounts of data or both can be handled by making ever bigger clusters of small machines. The strength of SQL is its powerful and widely known query language, with a large ecosystem of tools. This flexibility is hugely useful when consolidating information from diverse sources or accommodating variations in documents over time, especially as new application functionality is continuously deployed.
It has a moderate security architecture and is vulnerable to some security challenges. As PostgreSQL is free and open-source, anyone can use all its features for free.

A Foreign Key is a column or a group of columns of one table that references another column of another table and establishes a relationship between them.

Learn the fundamental concepts of databases, best-practices, and techniques to increase efficiency. The current data engineering solutions that companies require for data and query processing https://globalcloudteam.com/ demand a high learning curve that lacks in PostgreSQL. Although PostgreSQL is easy to deploy on multiple platforms, it does not have the same efficiency on every platform.
