One field or more might be written in just one operation, including updates to numerous sub documents and array elements. PostgreSQL ensures transactions are atomic, consistent, isolated, and durable (ACID). As it’s a relational database management system, PostgreSQL can guarantee that transactions follow each property of ACID. In MongoDB, the basic unit of storage is a serialized JSON document. MongoDB support various data types including nested documents, arrays, strings, dates, Boolean values, and numbers. MySQL, with its long-standing presence in the market, boasts a mature and robust user interface.
In a document database, a developer or team can own documents or portions of documents and evolve them as needed, without intermediation and complex dependency chains between different teams. 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. 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.
MongoDB vs PostgreSQL
At the same time, PostgreSQL is developed and maintained by the PostgreSQL Development group, which is used for the relational database management system. Since PostgreSQL handles relational databases, it exhibits an object-oriented nature. In MongoDB, postgresql mongodb all the contents of the database are documents and files. PostgreSQL and MongoDB support all major operating systems, including Windows, Linux, and Unix. PostgreSQL is a traditional relational database management system with a fixed schema.
- Limited data nesting can also be done using the TSV migration process in PostgreSQL to MongoDB.
- You can use PostgreSQL as the primary data warehouse or data source for various mobile, geospatial, analytics, and web applications.
- This also means that the database can only scale as much as the machine running it.
- While NoSQL databases work on storing data in key-value pairs as one record, relational databases store data on different tables.
- We use SQL to communicate with a database, and we can use SQL statements to perform tasks like updating or retrieving data from a database.
- MongoDB has a document model, making collaboration and development easier and faster to implement.
This ensures that replica servers have an up-to-date copy of the primary database. PostgreSQL also supports synchronous replication, where a transaction is not considered committed until all replicas have confirmed receipt of the transaction. Furthermore, what makes PostgreSQL extensive is catalog-driven events since it can dynamically manage and adapt to changes in the database schema.
Connect PostgreSQL to MongoDB: 2 Easy Methods
But MongoDB has succeeded, especially in the enterprise, because it opens the door to new levels of developer productivity, while static relational tables often introduce roadblocks. Also, if you have a flat, tabular data model that isn’t going to change very often and doesn’t need to scale-out, relational databases and SQL can be a powerful choice. But if you have many incumbent applications based on relational data models and teams seasoned just in SQL, a document database like MongoDB may not be a good fit.
If there is a need to scale, it can be easily done through horizontal scaling of more platforms. It can be used to manage data for anything from web applications to data warehouses. It is programmed in C and follows a monolithic architecture, which means that the components are completely united and work systematically.
Create a table
If you require a modern database to process data from various sources and in various formats, then go for MongoDB. If SQL database structure suits your application needs, PostgreSQL is a better choice. PostgreSQL uses joins to combine data from multiple tables into a single table.
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.

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. MongoDB is a NoSQL database with a flexible data model, high performance, and effective horizontal scaling.
It’s capable of powering massive applications regardless of it being measured by data sizes or users. This scale-out approach depends on the use of a growing number of smaller, generally more cost-effective machines. You can accelerate MongoDB’s query performance if you make indexes on fields in documents and sub documents. This database enables all document fields to be indexed and queried simply, as well as those that are deep within sub documents and arrays. So much of the conversation in the world of computer science covers isolation levels in database transactions. PostgreSQL defaults to the read committed isolation level, enabling users to adjust it to the serializable isolation level.
No-code Data Pipeline For your Database
Indexes are objects or structures that allow us to retrieve specific rows or data faster. Write-ahead logs enable sharing the changes made with the replica nodes, hence making asynchronous replication possible. Other kinds of replications include logical replication, streaming replication, and physical replication. 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.
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. We’re working hard on closing the gaps for data at rest encryption (DARE), as reported by both our community of users and our customers. MongoDB and PostgreSQL are trusted source that a lot of companies use as it provides many benefits but transferring data from it into a data warehouse is a hectic task.

Additionally, PostgreSQL uses the PostgreSQL Automatic Failover (PAF) to allocate a new primary if there’s a failure event. It offers several index types like B-tree, compound, text, geospatial, hashed, and clustered indexes. Determining the most suitable database management system for a specific use case is crucial in maximizing the efficiency and functionality of an application.
