![]() ![]() NoSQL Capabilities – PostgreSQL offers some NoSQL capabilities like JSON support, XML support and key-value storage with HSTORE. ![]() MySQL has fewer automatic checks which provides flexibility but also risks data corruption issues. MySQL has historically implemented a subset of SQL which sometimes deviates from formal standards.ĭata Integrity – PostgreSQL enforces stringent data integrity checks and constraints by default. Strict SQL Standards – PostgreSQL aims to strongly conform to SQL standards like ANSI, ISO, and SQL:2016. Object-relational vs Pure Relational – PostgreSQL supports additional data types, inheritance, user defined types, and other object-relational capabilities beyond a standard relational DBMS like MySQL. However, there are also important differences in features and capabilities: Replication and clustering for high availability.Views, Cursors and other advanced SQL functionality. ![]() ACID (Atomicity, Consistency, Isolation, Durability) compliant transactions.Support for fundamental SQL commands like SELECT, INSERT, UPDATE, DELETE etc.PostgreSQL and MySQL share many common features as traditional relational database systems: Overall, PostgreSQL provides more licensing flexibility while MySQL is more restrictive. So while the databases themselves are free, there may still be commercial costs around enterprise features, support, and cloud hosting that should be factored in. MySQL – MySQL offers MySQL Enterprise Edition ($5,000 per server per year), MySQL Cluster Carrier Grade Edition (pricing unavailable), and Amazon RDS for MySQL ($0.11 per hour) PostgreSQL – Key commercial options include EnterpriseDB Postgres Advanced Server ($5,000 per server per year) and Amazon RDS for PostgreSQL ($0.12 per hour) In addition to the core open source databases, both PostgreSQL and MySQL offer commercial distributions which include extra tools, plugins, technical support, and other services: This "copyleft" provision discourages some companies from using MySQL. However, companies who modify the MySQL source code are required to release their modifications under the GPL as well. MySQL uses the GPL license which also allows free use and distribution of the software. PostgreSQL uses the permissive PostgreSQL license which allows companies to use, modify, and distribute the software freely, even in proprietary products. However, there are some key differences in the licenses: Licensing and Costīoth PostgreSQL and MySQL are open source databases, so the core software can be used without paying license fees. So in summary, PostgreSQL has its roots in academia and benefits from constant evolution over 30+ years while MySQL was designed from the beginning to be a simple, fast, low-cost database option. Development of MySQL continues under Oracle, along with a fork named MariaDB led by some of the original MySQL developers. In 2010, Oracle acquired Sun Microsystems, which had previously acquired MySQL AB, the company behind MySQL. 2010 – Oracle acquired Sun Microsystems.2008 – Sun Microsystems acquired MySQL AB.1999 – MySQL AB founded to commercially distribute MySQL.MySQL was designed from the outset to be easy to use, nimble and low cost. It was created by David Axmark, Allan Larsson, and Michael "Monty" Widenius as a lightweight alternative to existing databases which were perceived as bloated, slow and expensive. MySQL originated in Sweden in 1995 with version 3.19. It has benefitted greatly from its constant evolution over 30+ years in academia. PostgreSQL is maintained by a large developer community and is overseen by the PostgreSQL Global Development Group. 2001 – PostgreSQL 8.0 added window functions, CTEs, and multiversion concurrency control.1996 – PostgreSQL released as open source.1996 – PostgreSQL 7.0 released, adding SQL support.1986 – POSTGRES project started at UC Berkeley.In 1996, POSTGRES was renamed to PostgreSQL to reflect its support for SQL. The initial database was named POSTGRES and was conceived by Stonebraker as a next generation successor to the Ingres database. PostgreSQL was created at the University of California at Berkeley by Professor Michael Stonebraker and has been under constant development since 1986. Understanding the origins of PostgreSQL and MySQL provides insight into their differing philosophies and design principles. ![]() Let‘s dive into the key differences that help determine when to use PostgreSQL vs MySQL for your next project. But depending on your specific needs, one may be a better fit than the other. But if you want an easy to use database with flexible schema and great community support, MySQL is hard to beat.īoth PostgreSQL and MySQL are mature open source databases with overlapping capabilities. If you need advanced SQL support, strong data integrity checks and excellent performance under heavy loads, PostgreSQL is likely the better choice. ![]()
