Oracle Database and MySQL top the latest DB-Engines ranking for database management systems (see chart below).
The DB-Engines Index utilizes a scientific method to calculate the popularity of every database management system in use (whether that be relational, NoSQL, time-series, etc.). As of January 2020, Oracle Database is ranked the most popular among all 350 databases that have been analyzed. MySQL, the open source database that is developed, distributed, and supported by Oracle takes the #2 spot.
Not only do Oracle Database and MySQL top the DB-Engines ranking, but their 2019 increase in popularity was higher than any other database’s (see the chart below). In other words, the popularity gap between Oracle and its database competitors is widening.
This latest DB-Engines ranking follows the November 2019 Gartner report, 'Critical Capabilities for Operational Database Management Systems', where Oracle Database again achieved the highest scores in all four Use Cases.
