PostgreSQL vs MongoDB: Choosing the Right DBMS

MongoDB has community support forums and other online sites like StackOverflow and servers fault. PostgreSQL has a wide range of community forums and commercial support as well. » moreCompetitive advantagesBuilt around the flexible document data model and unified API, MongoDB is a developer… Live resharding allows users to change their shard keys as an online operation with zero downtime. Although schema-free, documents of the same collection often follow the same structure.

MongoDB vs PostgreSQL

MongoDB and PostgreSQL are both different types of databases, and both serve different purposes. We will explore the features, advantages, and use cases that will lead to selecting these databases. In this article, we are discussing two databases, MongoDB and PostgreSQL.

PostgreSQL Trigger

MongoDB can use indexes to limit the number of documents it must inspect otherwise a scan operation is performed in every document in a collection, to select those documents that match the query statement . In PostgreSQL, indexing allows the database server to find and retrieve specific rows much faster as it have to “walk” a few levels deep into a search tree. 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.

  • In specific, GeoSpark seems to be the most complete spatial analytic system because of data types and queries supported.
  • This strength is due to the database’s stable progress over the years.
  • Other than these few differences, both databases are equally strong in terms of performance and will work well with any organization, customer, or business needs.
  • PostgreSQL employs an engineering-centric approach to almost everything.
  • Having a different syntax and structure of data than relational database management systems , it stores data in the form of documents.
  • Postgres employs SQL ultimately under the hood, a structured query language, to define, to access and to manipulate the database.
  • Learn more about them, how they differ, and how to determine which one is right for you.

On the other hand, the 3-Dimension spatiotemporal benchmark expands the aforementioned benchmarks and includes the time component. Nevertheless, the examined spatio-temporal queries have been designed specifically for the maritime domain and its specific applications. Thus, none of the above benchmarks are suitable for the evaluation. MongoDB is a NoSQL database where each record is a document comprising of key-value pairs that are similar to JSON objects with schemas. MongoDB is flexible and allows its users to create schema, databases, tables, etc. Documents that are identifiable by a primary key make up the basic unit of MongoDB.

No-code Data Pipeline For your Database

Normalized data models describe relationships using references between documents. This would be beneficial to use when embedding may result in data duplication but insufficient read performance advantages outweigh the implications of the duplications. On the other hand, MongoDB allows you to store data in any structure that can be quickly accessed by indexing, no matter how deeply nested in arrays or subdocuments.

MongoDB vs PostgreSQL

Everything you would ever want from a relational database is present in PostgreSQL. Given the recent addition of transaction capabilities to MongoDB, it wasn’t too surprising to see a win for Postgres in this one, but the magnitude of the difference was still impressive. The Postgres database management system measured between 4 and 15 times faster than MongoDB in transaction performance testing. Benchmarking databases that follow different approaches is harder still. Despite the different data models that MongoDB and PostgreSQL expose, many organizations face the challenge of picking either technology. Also, It does not support the ACID properties of the database properly.

Scale-out vs. Scale-up: What’s the Difference?

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. 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.

In PostgreSQL, developers regard replication as synchronous, often called 2-safe replication. In MongoDB, developers store related information using collections. On the other hand, in PostgreSQL, developers store related data information using tables. Some form of processing data in XML format, e.g. support for XML data structures, and/or support for XPath, XQuery or XSLT.

PostgreSQL uses the relational database model that depends on storing data within tables and utilizing the structured query language for database access. It has a large object facility, which provides stream-style access to user data that is stored in a special large-object structure. MongoDB supports a rapid, iterative MongoDB vs PostgreSQL cycle of development so well because of the way that a document database turns data into code under the control of developers. A relational database such as PostgreSQL uses the common SQL syntax. Since data is stored in structured table designs, you link data across tables using primary and foreign keys.

MongoDB vs PostgreSQL

Documents in MongoDB for the embedded data model must be smaller than the maximum BSON document size . Normalization is the process of structuring a relational database to reduce data redundancy, minimize anomalies in data modification, and improve data integrity. MongoDB has a document model, making collaboration and development easier and faster to implement.

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. MongoDB is a schema-free document high-performance database offering both free and paid plans.

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. If built-in scalability is desired, then MongoDB inherently can scale horizontally with native sharding. Scaling out by adding new nodes or shards can be configured with ease. Automatic failover and replication are also built into MongoDB where PostgreSQL requires either an extension or more configuration to support those features. Migrating to a NoSQL document database can be a challenge if you have a large data model. Take inventory of your software to check if you have business intelligence analysis and reporting tools as they may depend on a SQL database and will not be able to take advantage of a NoSQL database.

Mongodb vs PostgreSQL performance

A relational database will reject data that doesn’t adhere to column design rules. As your data volume grows, these two databases will handle large datasets in different ways. MongoDB uses sharding, which means it distributes data across multiple machines. All your data is stored on one server, increasing the CPU, storage and memory as you handle more data.
