What is the difference between SQL NoSQL MySQL and PostgreSQL?

PostgreSQL supports JSON and other NoSQL features like native XML support and key-value pairs with HSTORE. It also supports indexing JSON data for faster access. MySQL has JSON data type support but no other NoSQL feature. It does not support indexing for JSON.

What is difference between PostgreSQL and MySQL and MongoDB?

In this article, we compare MongoDB and PostgreSQL. PostgreSQL is a traditional RDBMS (relational database management system) SQL database, like Oracle and MySQL. MongoDB is a no-schema, noSQL, JSON database. MongoDB has a free version, but they also have hosted and enterprise paid versions.

What is SQL MySQL and NoSQL?

MySQL is used in the SQL database management system, a product from Microsoft corporation, where in NoSQL is a database type where SQL is necessary to access the document-based contents of the non-relational database management systems.

What is the difference between NoSQL and relational database?

A data structure used by the NoSQL database is vastly different from those used in a relational database. Some operations are faster in NoSQL than relational databases like MySQL. Data structures used by NoSQL databases can also be viewed as more flexible and scalable than relational databases.

Is PostgreSQL similar to MySQL?

What are the advantages of using MongoDB?

The rule of thumb when you use MongoDB is Data is that is accessed together should be stored together. Queries typically do not require joins, so the queries are very fast. Some NoSQL databases like MongoDB map their data structures to those of popular programming languages.
