In today’s digital age, where data drives decision-making, having a trustworthy and reliable database system is paramount. In an era of massive data influx, ensuring that data operations are consistent and reliable is vital. ACID transactions prevent data anomalies, providing a framework that safeguards data, which in turn reinforces trust in data-driven decisions. While atomicity ensures an all-or-nothing approach during transaction processing, durability ensures that this ‘all’ remains intact and unaffected by unforeseen system challenges, cementing the changes permanently. Consistency ensures that every transaction in a database brings it from one valid state to another. Before the start of a transaction, the database is in a consistent state, and it should return to this state once the transaction is completed.
The parallel processing of data requests dresses load on one server and ensures data consistency while maintaining application uptime. Even though it is popular, it still lacks in a few things compared to other databases. It requires a lot of storage and doesn’t clean up the disk space automatically.
Performance, security, and reliability
On the other side of the spectrum, we have PostgreSQL, a venerable open-source relational database that embraces the traditional SQL paradigm. It excels in handling structured data, embodying a rock-solid foundation of ACID (Atomicity, Consistency, Isolation, Durability) compliance. MongoDB uses BSON (Binary JSON) and MQL, an alternative language to SQL. BSON allows for certain data types that are not used with regular JSON, such as long, floating-point, and date. MQL too offers similar features as SQL with some additional capabilities.
That’s our quick summary — now let’s take a deeper look at each database in turn before we reach our detailed comparison. But if a SQL database is a better fit for your requirements, PostgreSQL should work for you. Similarly, Astera Centerprise also allows connectivity to a PostgreSQL instance within the scope of an ETL pipeline.
MONGODB TUTORIAL
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. The volume of spatial data is increasing exponentially on a daily basis.
Alongside its key features, we’ll look at 5 major differences between the two. PostgreSQL uses logical and stream replication plus PAF to offer availability. PostgreSQL also provides various index types, including B-tree, hash, GIN, GiST, and Sp-GiST. MongoDB organizes each document into collections, with each having a unique ObjectId, which you use to identify a document. Regardless of the database you choose, partnering with a third party for support and guidance is a must.

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.
There are other benefits of using Integrate.io when choosing between MongoDB vs. PostgreSQL. The platform has a unique pricing model that charges you for the number of connectors you use and not the data you consume. Its flexible document model, based on BSON (Binary JSON), aligns well with modern programming paradigms and eliminates the need for complex object-relational mapping (ORM) layers.
Primary support for SQL
Their distributed architecture processes move data to improve performance. Data moves between replicas in PostgreSQL and between partitions in MongoDB. Concurrency is the ability of a database system to manage multiple transactions at the same time. Concurrency allows multiple users to access and modify data without causing inconsistency issues or conflicts.
It assumes there are no conflicts between most concurrency write operations, which allows people to modify data at the same time without acquiring locks. It also creates a new revision ID for the document, which allows multiple documents with the same data to exist simultaneously. 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.
SQL
For data ingestion we used the mongoimport tool to import data into MongoDB database. The total size the dataset occupied in the collection in MongoDB is 116 GB and each record has a size of about 275 bytes. Q7ii adds yet another factor, the geographical area and performs the same functionality as Q7i. Q8i returns the average speed for every vessel passed in the query whereas Q8ii takes into account the geographical area. The geographical polygons that used are uniformly selected and occupy equal size (P1ran, P2ran, P3ran).
- This statement uses the GeoJSON geographical query features of MongoDB to do that.
- This function is especially useful when you query data across multiple tables, using the relationships you define to connect data sets.
- We previously discussed how to use pgvector’s IVFFlat index type to speed up search queries for ANN queries, but it has performance limitations at the scale of hundreds of thousands of vectors.
- Since MongoDB 4.4, queries implemented against replica sets produce improved and predictable performance through “hedged” reads.
- Our no-code data pipeline platform comes with out-of-the-box connectors for both MongoDB vs. PostgreSQL, helping you unify your data and gain more meaningful insights from your data warehouse.
MongoDB was built to scale out horizontally, as it often combines its power with additional machines and doesn’t rely on processing power. Furthermore, you can also update related data in a single atomic write operation while applications issue fewer queries to complete common operations. Documents in MongoDB for the embedded data model must be smaller than the maximum BSON document size (16 MB). Normalization is the process of structuring a relational database to reduce data redundancy, minimize anomalies in data modification, and improve data integrity. MongoDB provides driver support for some of the best database languages like Python, R, Java, Scala, C, C++, C#, Node.js, and many more.

He writes tutorials on analytics and big data and specializes in documenting SDKs and APIs. He is the founder of the Hypatia Academy Cyprus, an online school to teach secondary school children mongodb vs postgresql programming. MongoDB is the most popular NoSQL database today and with good reason. This e-book is a general overview of MongoDB, providing a basic understanding of the database.
