MongoDB vs PostgreSQL: 8 Critical Differences Learn

One of the most frequently cited drawbacks of NoSQL databases is that they don’t support ACID (atomicity, consistency, isolation, durability) transactions across multiple documents. With appropriate schema design, single-record atomicity is acceptable for lots of applications. However, there are still many applications that require ACID across multiple records. It adopts a relational model, provides comprehensive SQL capability, carries an extensible architecture, and is driven by an enthusiastic community. It popularizes the document model, provides built-in scaling and high availability, offers an integral developer experience, and is driven by a sharp-minded for-profit business entity.

Of course, this affects functionality and makes MongoDB useful than PostgreSQL when both of them are compared. MongoDB is quite reliable and users are always free to distribute the database to a number of nodes. Currently, PostgreSQL is controlled by PostgreSQL Global Development.

Architecture/Document Model

There are a very large number of contributors as well as organizations that are a part of it. The best thing about this database is it considers SQL for storing the data into the tables and for accessing the database. When I was new with web development, I was using PHP for backend and MySQL for database. Because of too many reasons including npm, express, community, fast coding and etc. If your JS skills are enough good, I recommend to migrate to Node.js and MongoDB.

Alongside its key features, we’ll look at 5 major differences between the two. PostgreSQL uses load balancing, connection pooling tools, and partitioning to offer scalability. PostgreSQL uses MVCC, data snapshots, flexible isolation levels, and deadlock detection to provide concurrency.

As an example the response time in Q6 in polygon P3p sample 1000 is the same as in the other polygons for the same amount of time intervals, although the volume of data returned differs significantly. The same behaviour is observed in the other samples of timestamps for both queries. SPEC, BAPco and TPC benchmarks are not suitable for large database environments and they cannot be applied for spatiotemporal data. However only three queries from SEQUOIA 2000 and one query of PGS-DBMS include the temporal component. Furthermore, Jackpine’s micro- and macro benchmarking consist only of spatial queries. On the other hand, the 3-Dimension spatiotemporal benchmark expands the aforementioned benchmarks and includes the time component.

If you’re not familiar with what NoSQL databases are or the different types of NoSQL databases, start here. If choosing between Postgres and MySQL is hard, then choosing between Postgres and MongoDB is no easier. And as both databases are heading upward, ico development company the choice will only become harder 🤷‍♂️. Most companies use databases to support their internal infrastructure, both Postgres and MongoDB permit this usage. It will help simplify the ETL and management process of both the data sources and destinations.

Support & Community

Each document is a JSON-like structure that can contain nested fields and arrays. MongoDB is designed to handle unstructured and semi-structured data. These sets allow you to record and replay processes on an as-required basis. MongoDB uses synchronous replication, which involves multiple repositories or systems that update at the same time. MongoDB is a document database and uses BSON for processing its data whereas PostgreSQL is a relational database that uses traditional SQL for its processing. Its completely automated pipeline offers data to be delivered in real-time without any loss from source to destination.

  • MongoDB is also open-source but has paid tiers like Enterprise and Atlas for the cloud.
  • Alongside its key features, we’ll look at 5 major differences between the two.
  • That’s a simpler step to take if you’re working on a new application or intend to modernize one that already exists.
  • All in all, don’t use a NoSQL database just cause you have the data type matching this tech, have both SQL and NoSQL at the same time.

These databases can support petabytes of unstructured data and can be used in analytics and reporting. For example, suppose that you need to import and store data from web pages with various document structures so that you can predict future sales using machine learning. MongoDB will support unstructured data from HTML pages and provide the performance and analytic capabilities for your machine learning predictions. These predictions could be used in front-end reporting for sales and marketing to determine the products that will sell the best in coming years and the most effective price structure. PostgreSQL uses a streaming replication method where changes made to the primary server are sent to replica servers through WAL files in real time. This ensures that replica servers have an up-to-date copy of the primary database.

PostgreSQL is also pretty universally supported in terms of language libraries and frameworks, without having to make compromises on how we want to store and layout our data. For those who like to jump right in and learn by doing, one of the easiest ways to get started with NoSQL databases is to use MongoDB Atlas. Atlas is MongoDB’s fully managed, global database service that is available on all of the leading cloud providers. Depending on the NoSQL database type you select, you may not be able to achieve all of your use cases in a single database.

MongoDB and Postgres differ in so many aspects like scaling and consistency. However in this case it seems these differences don’t matter that much. Hey Krunal, your requirement sounds pretty clear and specific to what you want to do with that data.

Finally, polygons relating to the intersection in Q9 were also uniformly selected within Mediterranean Sea and each polygon’s area from every group is of equal size. This means that the geographical areas of PInt1, PInt3, PInt5 are equal as well as PInt2, PInt4, PInt6. MongoDB Atlas has a globally aware, multi-cloud platform ready for you, which you completely manage yourself. MongoDB Atlas makes building and configuring these clusters simpler and quicker. This makes it easier for a user who has previous transaction experience to contribute to any application. But if a SQL database is a better fit for your requirements, PostgreSQL should work for you.

The translation of SQL to MongoDB queries may take additional time to use the engine which could delay the deployment and development. MongoDB tends to focus on fast data operation but lacks the data security that PostgreSQL seems to possess. It’s quite tasking on the memory, as the denormalization process usually results in high memory consumption. One major drawback of MongoDB, however, is that you can’t easily join tables. Hence anyone can use its features and make modifications to the code with ease when necessary. Replica sets can be implemented across various data centers too, as they would come in handy in case of regional outages.

What is MongoDB

PostgreSQL is an open-source relational database management system (RDBMS) that extends the SQL language. PostgreSQL is backed by over 35 years of active development on its core system by its developer community which contributed to its consistency, integrity, correctness, and stability. Many relational database platforms allow you to work with nested structures comfortably as well and PostgreSQL is not an exception. You can store your data in table columns that have a JSON data type and leverage PostgreSQL built-in functions for working with JSON. In the following queries, the purpose is to measure the impact of the number of vessels in each system’s performance. Thus, we repeated a class of experiments for a set of (10, 100, 1000) vessels.

MongoDB also supports database transactions across many documents, so chunks of related changes can be committed or rolled back as a group. 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.

Numerous extensions offer extra functionality, such as PostGIS — a geospatial analysis module. PostgreSQL complies with a wealth of security standards and includes various features for backup, reliability, and disaster recovery (typically via third-party tooling). PostgreSQL employs an engineering-centric approach to almost everything.
