Hence, there is no need to capitalize strings while querying.Īnother difference in terms of coding lies in the characters' sets and strings. On the other hand, MySQL is not case-sensitive. This means that developers must capitalize strings as they appear in the database otherwise, the query will fail. On the one hand, PostgreSQL is case-sensitive. MySQL, a couple of differences should be considered. When it comes to coding in PostgreSQL vs. This does not have to be a disadvantage, but rather something to watch out for. Therefore components used alongside the database might not comply with PostgreSQL formats. Nonetheless, despite the benefits of using alternative formats to store data, it can also be more complex to implement such data formats, considering they do not follow a well-established standard. For instance, by accepting arrays as a data type, PostgreSQL can also offer host functions that are compatible with those arrays. The main benefit of having a variety of options available is that it can increase functionality. In contrast, PostgreSQL further supports XML, arrays, user-defined type, and hstore, thus offering the ability to operate with more data types than MySQL. So far, JSON support remains one of the leading NoSQL features that MySQL has integrated. Up until the launch of the MySQL 5.7.8 version, the database system did not support JSON files. However, things were not always this way. PostgreSQL vs MySQL: key differences Data TypesĬurrently, both PostgreSQL and MySQL enable developers to work with JSON as a data type in tables. Regarding community support, both PostgreSQL and MySQL benefit from active communities as well as extensive documentation support. According to the index, MySQL is in the second position and PostgreSQL in the sixth. However, to be more precise, according to popularity statistics from May 2021, MySQL is still more popular than PostgreSQL, as the DB-Engines Ranking highlights.įurthermore, this data is aligned with the TOPDB Top Database Index, which is based on Google search results. PostgreSQL vs MySQL: which one is more popular?īoth PostgreSQL and MySQL are among the most popular databases available in the market. In turn, MySQL offers almost the same features (or very identical ones), and since the MySQL 5.7 version release (2015), it also started including NoSQL features. Additionally, PostgreSQL also integrates stored procedures, views, constraints, triggers, roles and further supports NoSQL. They both use tables as their core component, meaning that the data is organized into rows and columns. In terms of structure, MySQL and PostgreSQL are actually pretty similar. Thus, ORDBMS can include the concept of classes, objects, and inheritance. These systems consist of a relational model, meaning that it is still possible to relate values and tables while also following the object-oriented model's principles. Plus, the values within each table can be related to each other, and tables can even relate to other tables. Hence the data is stored in a structured format (with columns and rows). RDBMS vs ORDBMSīefore moving on to the comparison between PostgreSQL vs MySQL, let's first understand how ORDBMS differs from RDBMS. Plus, it also stands out in the community for its ease of use. Over the years, MySQL has built quite an impressive and reliable reputation. Moreover, this database is managed and owned by the Oracle Corporation. It is an open-source (available under the GNU GLP) Relational Database Management System (RDBMS). MySQL was introduced to the market in 1995, shortly before PostgreSQL.

PostgreSQL is an open-source Relational Database Management System ( RDBMS) that can also be considered an Object-Relational Database Management System ( ORDBMS) since it supports some object-oriented features, such as table inheritance and function overloading. Currently, its development is under PostgreSQL Global Development Group. PostgreSQL was first released in 1996 and created in the University of California, at the Computer Science Department. PostgreSQL vs MySQL: which one is more popular?

Further, it entails which one to choose and highlights the importance of considering the application's requirements. In that sense, this article provides a deep comparison between PostgreSQL and MySQL, considering aspects such as the data types, ACID compliance, indexes, replication, and more. Therefore, it is essential to understand their differences in order to choose the most appropriate one for each case. Both options offer many advantages and are highly competitive. There are many Relational Database Management Systems (RDBMS) available in the market, and PostgreSQL and MySQL are among the two most popular ones.
