Hence an ORDBMS supports additional features such as inheritance, classes, and objects. This, therefore, implies that despite the tables being linked and related, other elements of the Object-Oriented Management System are also available. An Object-Oriented Relational Database Management System contains qualities of both a Relational Database Management System and an Object-Oriented Relational Database Management System. PostgreSQL is an Object-Oriented Relational Database Management System (ORDBMS), while MySQL is a Relational Database Management System (RDBMS). Relational Database Management System (RDBMS) Object-Oriented Relational Database Management System (ORDBMS) vs. You can try out other alternatives if the two do not meet your needs. In addition, there are more third-party tools available for MySQL.Īlso, it is essential to note that MySQL and Postgres are not the only databases. Generally, MySQL is widely used than PostgreSQL, meaning most DBAs and developers are more familiar with it. Allows use of two or more B-tree indexes Object statistics Outstanding object statistics Fairly good object statistics Stack Overflow questions 89.3K 532K GitHub Rating 5.6k 3.34k Famous companies using the product Instagram, Groupon, and Netflix Uber, Twitter, and Airbnb B-tree Indexes B-tree indexes are merged at runtime to evaluate the dynamically converted predicates. Default values Only the system level can change the default values The default values can both be overwritten at the Statement and session levels. MySQL has a dynamic ecosystem with variants such as Galera, MariaDB, and Percona. However, it is taking an entirely new shape with the introduction of new features on the latest versions. Ecosystem Postgres has limited high-end options. MySQL does not support materialized views. MySQL performs well in OLAP & OLTP systems when working with only read speeds Join capabilities Has good join capabilities Limits join capabilities Support for materialized views and temporary tables Supports temporary tables and materialized views. Best suited PostgreSQL performs excellently when executing complex queries.
Performance Used in large systems where the read and write speeds matter most It is used chiefly for web-based projects that require a database for easy data transactions. It has significant community contributors whose sole purpose is to maintain the existing features by occasionally releasing new features. Besides, security enhancements and new cutting-edge features are periodically released. Community Support The innovative community aims at ensuring it remains the most advanced database while the active community regularly improves the existing features. For example, it does not support check constraints. For instance, it is only compliant with ACID while using NDB and InnoDB cluster storage engines SQL compliant PostgreSQL fully complies with SQL MySQL is partially compliant with SQL. The centrally managed account is prevented due to the lack of a pluggable authentication Differences between PostgreSQL and MySQLīelow is a table comprising of the significant differences between Postgres and MySQL Parameter PostgreSQL MySQL Forks 2.4K 1.6K ACID compliance PostgreSQL fully complies with ACID MySQL is partially compliant with ACID.Tables used for triggers and procedures are pre-locked.
