PostgreSQL is an open-source database management system, which is a powerful tool for managing data. It is also the world’s leading open-source database system. MySQL and Postgresql are open-source databases; they are publicly available to use and modify. This makes both of them very accessible to people with limited technological knowledge. In addition, it makes both of them useful as a starting point for developing new applications. On the other hand, proprietary databases like Microsoft’s SQL server are more more difficult for non-developers to access. In this article, you will learn about Difference between PostgreSQL and MySQL.

Difference Between PostgreSQL and MySQL

Parameter PostgreSQL  MySQL
ACID PostgreSQL is fully ACID compliant. MySQL is ACID compliant only when used with the InnoDB and NDB clustered storage engines. 
Open source PostgreSQL is released under the PostgreSQL License, a free and open source license. This is similar to the BSD and MIT licenses.  The MySQL Project has made its source code available under the terms of the GNU General Public License. 
Compatibility with SQL  PostgreSQL is mostly compatible with SQL.  MySQL is partially compatible with SQL. For example, check constraints are not supported. 
Used in Commonly used in large systems where read and write speeds are important It is primarily used in web-based projects that require a database for simple data transactions.
Works well with PostgreSQL works well when running complex queries. Best Suite MySQL works well in OLAP and OLTP systems when you only need read speed. 
Ecosystem Postgres had limited high-end options. However, it is changed by new features introduced in the latest version. MySQL has a dynamic ecosystem that includes variants such as MariaDB, Percona, and Galera. 

What is PostgreSQL 

Postgres is an object-relational database management system (ORDBMS). It was developed in the Computer Science Department of the University of California.

 PostgreSQL is an enterprise-class relational database system. Setup and installation are easy. Provides support for SQL and NoSQL. It has a great community who are happy to help if you run into problems using PostgreSQL. PostgreSQL is considered an ideal solution for performing complex, large-scale data manipulation. PostgreSQL and MySQL are compared because the former is better at handling abnormal database situations. PostgreSQL offers more features than other database management systems (users confirm this). It does more than just store information about tables and columns. Data types, index types, and functional languages ​​can also be defined.

Advantages of PostgreSQL

  • PostgreSQL’s write-ahead logging makes PostgreSQL a very fault-tolerant database. 
  • The PostgreSQL source code is freely available under an open-source license. 
  • PostgreSQL can run web apps and dynamic websites such as the LAMP stack option. 
  • PostgreSQL can be used as a spatial data store for location-based services and geographic information systems. 
  • Postgres is easy to use and doesn’t require a lot of training to pick up. 

Disadvantages of PostgreSQL

  • PostgreSQL is not owned by any organization. As such, it struggled to spread its name despite being fully featured and on par with other DBMS systems.
  • It is slower than MySQL in terms of performance metrics.
  • Many open-source apps support MySQL but may not support PostgreSQL.

What is MySQL

It is one of the most popular open-source relational database management systems (RDMS). The data for this table is stored in a table, making it easier to perform CRUD (create, read, update, and delete) operations. MySQL is an excellent choice for scalable web applications. One reason is that it’s standardized in the LAMP stack, an open-source suite of web applications consisting of Linux, Apache HTTP Server, MySQL, and PHP. Content management systems such as Drupal, Joomla, and WordPress rely on MySQL.

Key differences between Postgresql and MySQL

  • PostgreSQL is an object-relational database management system (ORDBMS), and MySQL is a community-driven DBMS system.
  • PostgreSQL supports modern application features such as JSON, XML, etc., but MySQL only supports JSON.
  • Comparing the performance of PostgreSQL and MySQL, PostgreSQL performs well when executing complex queries, and MySQL performs well in OLAP and OLTP systems.
  • PostgreSQL is entirely ACID compliant, but MySQL is ACID compliant only when used with InnoDB and NDB.
  • PostgreSQL supports materialized views, but MySQL does not.

Conclusion 

It is a popular and widely used DBMS system. It is an RDBMS (Relational Database Management System) and works primarily with a relational database model. This makes database management easier and more flexible. Postgres is an object-relational database management system (ORDBMS). MySQL is a community-driven DBMS system. PostgreSQL has an active community that accelerates its development.
