Key Difference Between Mysql and Postgresql Looking to level up your relational database skills? Start with a SQL course before you move to these robust database management systems. However, its architecture provides inferior scalability for high-concurrency applications. Its MVCC architecture allows low degrees of transactional integrity but MySQL database system usage is more with a vast user base. MySQL has limited support for extensibility and has lock-based concurrency management with a shared-everything architecture. MySQL was introduced by Michael Widenius in the 1990s, and later in 2009, Oracle Corporation purchased it. While PostgreSQL database system usage is less with a smaller user base, its architecture offers superior scalability for high-concurrency applications MySQL

Further, its MVCC architecture allows high degrees of transactional integrity. One of the best features of PostgreSQL is the possibility to add new functions, index types, and other features, which use a multi-version concurrency control (MVCC) system with a shared-nothing architecture. PostgreSQL came into existence in the 1980s and was made available as an open-source project in 1996. MySQL on the other hand is a pure relational database system that is based on the dependability and consistency of the system.īefore jumping into the technical differences between them let’s take a look at their history and architecture.
