MongoDB vs MySQL vs PostgreSQL What are the differences?

The upsides of SQL include the vast ecosystem of tools, integrations, and programming languages built to use SQL databases. It is likely that you can easily find help to make your SQL database project in general and PostgreSQL project in particular work. PostgreSQL can be run as an installed, self-managed version, or as a database-as-a-service on all of the leading cloud providers.

This is a reliable, enterprise-grade, open-source SQL database with more than three decades of history behind it. All you could ever look for in a relational database is here for you. PostgreSQL ensures transactions are atomic, consistent, isolated, and durable (ACID).

This provides redundancy and protection against any downtime that might occur in the event of a scheduled break for maintenance or a system failure. 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.

If you need to add a new field to a document, then the field can be generated without impacting other documents in the collection or updating an ORM or a central system catalog. MongoDB supports complete isolation while a document is being updated. Any errors would trigger the update operation to roll back, reversing the change and ensuring that the clients get a consistent view of the document. PostgreSQL also carries no licensing cost, eliminating the risk of over-deployment. Its dedicated group of enthusiasts and contributors regularly find bugs and solutions, chipping in for the overall security of the database system. Experience Postgres’ NoSQL performance by trying the pg_nosql_benchmark on GitHub.

Mongo is also simple to setup and use, and it’s speed as a document-object storage engine is first class. Writing queries is a nightmare
While N1QL is similar to SQL and it’s easier to write because of the familiarity, that isn’t entirely true. Creating an index with 5 fields, and only using 4 of them won’t result in Couchbase using the same index, so you have to create a new one. N1QL queries
Configuring the indexes correctly is next to impossible. It’s poorly documented and nobody seems to know what to do, even the Couchbase support engineers have no clue what they are doing. This means my stack consists of about 80% software I already know well, but I do allow myself 20% of the stack to explore tech I have less experience with.

MongoDB uses sharding, read scalability, and automatic data balancing to offer horizontal scalability. MongoDB organizes each document into collections, with each having a unique ico development company ObjectId, which you use to identify a document. While both PostgreSQL and MongoDB make amazing databases, it ultimately comes down to choosing what’s right for your business.

Key Differences Between MongoDB and PostgreSQL in Detail

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. PostgreSQL is an object-relational database management system that uses tables, rows, and columns to store data.

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. Every MongoDB shard is run as a replica set — a synchronized cluster consisting of three or more servers that keep replicating data between them.

No-code Data Pipeline For your Database

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. We’ll go over some basic differences to help you decide which database application is right for you. If you’re searching for a database, you’ll probably come across several vendors, two of which are MongoDB and PostgreSQL.

  • It increases the efficiency of database data retrieval operations.
  • But in  comparing JSON operations between PostgreSQL and MongoDB, there are benchmarks that show an advantage for both databases.
  • For enterprise organizations switching to an open source database, understanding the benefits and weaknesses of that database is key.
  • The MongoDB Source object in the product lets the user load a MongoDB database of their choice and use it within the scope of an ETL pipeline.
  • In MongoDB, the basic unit of storage is a serialized JSON document.

Using this system, you can perform complicated joins and form relationships between tables. This function is especially useful when you query data across multiple tables, using the relationships you define to connect data sets. In contrast, PostgreSQL uses logical and stream replication to ensure high availability. Logical replication selectively replicates specific tables or subsets of data. Streaming replication creates standby replicas that receive changes in the primary database. Additionally, PostgreSQL uses the PostgreSQL Automatic Failover (PAF) to allocate a new primary if there’s a failure event.

ACID transactions for changes to many documents

MongoDB provides driver support for some of the best database languages like Python, R, Java, Scala, C, C++, C#, Node.js, and many more. These MongoDB libraries and drivers support all of MongoDB’s features, giving high performance and scalability in all applications. Since it’s non-relational, MongoDB uses collections instead of tables. A foreign key is simply a set of attributes in a table that refers to the primary key of another table. It makes queries execute faster as it’s in a serialization format that effectively archives JSON-like documents. By storing data in fields such as nested subdocuments and arrays, related information in JSON documents can be stored together for quick query access through the MongoDB query language.

Although a number of other benchmarks limited to a specific database or application, Jackpine presents one important feature, portability in terms that can support any database (JDBC driver implementation). It supports micro benchmarking that is a number of spatial queries, analysis and loading functions with spatial relationships and macro benchmarking with queries which address real world problems. The object portion of this database relates to the varied extensions allowing it to incorporate alternative types of data, including JSON data objects, XML, and key/value stores.

Connect to a database

Much of the discussion in the computer science realm is about isolation levels in database transactions. PostgreSQL defaults to the read committed isolation level, and allows users to tune that up to the serializable isolation level. It is built on a distributed, scale-out architecture and offers a comprehensive cloud-based platform for managing and delivering data to applications. MongoDB handles transactional, operational, and analytical workloads at scale.

In this way, related information can be stored together for fast query access through the rich and expressive MongoDB query language. On the other hand, MongoDB is a NoSQL database that stores data in a flexible, document-oriented format. It uses modified JSON to store data and provides a rich query language for retrieving and manipulating data.

Like MySQL and other open source relational databases, PostgreSQL has been proven in the cauldron of demanding use cases across many industries. In a relational database, the data in question would be modeled across separate parent-child tables in a tabular schema. This means that updating all the records at once would require a transaction. We have chosen Tibero over Oracle because we want to offer a PL/SQL-as-a-Service that the users can deploy in any Cloud without concerns from our website at some standard cost. We have chosen Tibero over Oracle because we want to offer a PL/SQL that you can deploy in any Cloud without concerns. SQLite’s simplicity actually avoids most of these experiences, which is not helpful to you if that is what you hope to learn.
