MongoDB vs PostgreSQL: 15 Critical Differences

It enables database administrators to provide high data redundancy and high availability of data. 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.

One of the most impressive details about PostgreSQL is that it offers support for all transaction isolation levels specified in the SQL standard, along with serializable. MongoDB has enjoyed widespread adoption as it has become the biggest modern database — it’s considered the go-to database by many developers. Due to the dedicated MongoDB community and engineering, it’s become a comprehensive platform that serves developers’ needs to an exceptional degree. MongoDB relies on a distributed architecture allowing users to scale out across numerous instances. It’s capable of powering massive applications regardless of it being measured by data sizes or users.

What is MongoDB?

This work is motivated by the question of which of those data storage systems is better suited to address the needs of industrial applications. In particular, the work conducted, set to identify the most efficient data store system in terms of response times, comparing two of the most representative of the two categories (NoSQL and relational), i.e. Furthermore, the average response time is radically reduced with the use of indexes, especially in the case of MongoDB. MongoDB is an open-source software from MongoDB Inc used for non-relational database management systems. At the same time, PostgreSQL is developed and maintained by the PostgreSQL Development group, which is used for the relational database management system.

As an astute reader should already be able to tell, the real question is not MongoDB vs. Postgres, but the best document database versus the best relational database. The serialization format stores documents and skips keys that are not required in the query, making it faster. Data is a fundamental component of every business process, and a database management system is an essential requirement to store this data with security and controlled accessibility. 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.

Extensibility support

While both are designed to store and manage data, they have some significant differences in architecture, functionality, performance, and scalability. In this article, we will explore the key differences between MongoDB and PostgreSQL to give you a better understanding of which one to choose based on your specific requirements. In order to evaluate these modern, in-memory spatial systems, real world datasets are used and the experiments are focusing on major features that are supported by the systems. The results show the strengths and weaknesses of the compared systems. In specific, GeoSpark seems to be the most complete spatial analytic system because of data types and queries supported. It is imperative for the research community to contribute to the clarification of the purposes and highlight the pros and cons of certain distributed database platforms.

  • Therefore, in a relational database, the data would be modeled across independent parent-child tables in a tabular schema.
  • 4 in which client application always interact with the primary node and the primary node then replicates the data to the secondary ones.
  • The main challenges in spatial partitioning are the spatial data skew problem which can result in bad response time through load imbalance and boundary objects problem which can lead to incorrect query results.
  • Fields can differ based on the document it is catering to, therefore, there’s no need to declare the structure of documents to the system — documents are self-describing.
  • It is widely used in the healthcare, banking, and manufacturing industries due to its innovative backup mechanisms.
  • The video ends with a summary of the main points and a recommendation for choosing a database management system for a project in 2023.

This SQL database has approaches for boosting concurrency, handling indexing, introducing optimizations, and enhancing performance — such as table partitioning, advanced indexing, among additional functions. As with Linux, PostgreSQL is a great example of an open-source project that has been managed well. It’s one of the most widely adopted relational databases, and it emerged from the POSTGRES project that began in 1986 at the University of Berkeley.

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. 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. When viewing documents, you will recognize the ever popular JSON format with key/value pairs that is language agnostic. PostgreSQL is the go-to choice for applications where data accuracy, complex transactions, and strict adherence to business rules are paramount.

In order to achieve high performance, the system partitions time consuming spatial query components into smaller tasks and process them in parallel while preserving the correct query semantics. The main considerations for data partitioning is to avoid high density partitioned tasks and to handle properly boundary intersecting objects. Hadoop-GIS takes advantage of spatial access methods for query processing and provides a real time spatial query engine (RESQUE) which supports an in-memory indexing on demand approach. There are challenges in managing and querying the massive scale of spatial data such as the high computation complexity of spatial queries and the handling of the big data nature of them.

Difference Between MongoDB vs PostgreSQL

MongoDB’s horizontal scalability and high availability mean it’s ideal for handling transactional data in financial systems. MongoDB is a NoSQL database with a flexible data model, high performance, and effective horizontal scaling. Ultimately, the best choice of a database depends on the specific needs of the project. As well as its mature mongodb vs postgresql which is better query planner and optimizer, PostgreSQL provides such performance optimizations as table partitioning, read query parallelization, and JIT (just in time) expression compilations. 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.

MongoDB automatically triggers a failover that elects a new primary node if a primary node becomes unavailable. MongoDB uses MongoDB Query Language (MQL) which allows you to interact with the document-oriented structure of MongoDB. MQL is rich in features and supports projection, aggregation frameworks, document querying, aggregation pipelines, geospatial queries, and text searches. Unlike in NoSQL databases, PostgreSQL’s basic storage unit is a row, called a tuple. Each tuple holds a single record under a specific data type that the column defines. Alongside the data values, each tuple also contains metadata like the primary key, which identifies each tuple within a table.

Security, performance, and consistency you can rely on

A schema allows for strong data consistency and integrity, as each column holds a specific data type. MongoDB and PostgreSQL are different types of databases that have distinct data models. It stores data in dynamic JSON-like documents and supports easy query, manipulation, and storage of data. As you may know, PostgreSQL refers to itself as an open-source object-relational database system.

MongoDB allows any field of a document, including those deeply nested in arrays and subdocuments, to be indexed and efficiently queried. MongoDB allows you to store data in almost any structure, and each field – even those deeply nested in subdocuments and arrays – can be indexed and efficiently searched. Postgres or Postgre SQL is an Object-Relational Database Management System(ORDBMS). It is an open-source and free database system that can use and extend the SQL language with other features. Initially, it was famous as Postgres, which refers to the Ingres database developed as a project at the University of California, Berkeley.

These features make it able to work with a polyglot database environment, which means it’s good for complex industries that want to optimize their storage. MongoDB, though, supports a fast, iterative development cycle so effectively due to the way in which document databases transform data into code under developer control. This speedy performance is disrupted by the nature of tighter tabular data models that are used in relational databases. Postgres employs SQL ultimately under the hood, a structured query language, to define, to access and to manipulate the database. Postgres does use its own flavor of SQL called PL/pgSQL (procedural language/postgreSQL). The big difference between the two is that the latter can perform more complex queries than SQL.
