PostgreSQL vs. MySQL Features and Comparison
Databases are logically modeled storage spaces for all kinds of different information (data). Each database, other than schema-less ones, have a model, which provide structure for the data being dealt with.
Relational Database Systems implement the relational model to work with the data. Relational model shapes whatever information to be stored by defining them as related entities with attributes across tables (i.e. schemas).
MySQL is the most popular one of all the large-scale database servers. It is a feature-rich, open-source product that powers a lot of websites and applications online. Getting started with MySQL is relatively easy, and developers have access to a massive array of information regarding the database on the internet.
PostgreSQL is the advanced, open-source [object]-relational database management system which has the main goal of being standards-compliant and extensible. PostgreSQL, or Postgres, tries to adopt the ANSI/ISO SQL standards together with the revisions.
PostgreSQL
The developer is PostgreSQL Global Development Group, and the initial release was in 1989
It's free and open-source software.
PostgreSQL is ACID compliant from the ground up and ensures that all requirements are met.
PostgreSQL is mostly SQL compliant.
PostgreSQL supports Master-Standby replication.
It is widely used in large systems where the speed of reading and writing is essential.
Postgres wants some more labor to install, configure and manage.
Postgres supports some data structures that MySQL does not support. Like Location, array, JSON.
Cloud systems providers support this structure.
MySQL
The developer is Oracle and the initial release was in 1995.
It's now owned by Oracle Corporation and offers several paid editions for proprietary use.
MySQL is only ACID compliant when using InnoDB and NDB Cluster Storage engines.
MySQL is partially compliant on some of the versions
MySQL supports Master-Standby replication.
It is a widely chosen for web-based projects that need a database simply for straightforward data transactions.
It seems to be easier to install, configure and manage MySQL.
MySQL often works by creating temporary tables for complex queries.
Cloud systems providers support this structure.
