Oracle 19c, SQL Server 2019, Postgresql 12 and MySQL 8 database systems comparison


This article presents a comparative analysis of four popular database technologies. Commercial Oracle Database and SQL Server systems are compared with open source database management systems: PostgreSQL and MySQL. These systems have been available on the market for over a dozen years. Versions released in 2019 were selected for testing and comparasion. For the purposes of the comparative analysis, a database schema was developed and instantiated. Then, test scenarios were developed. They were prepared on the basis of the most popular operations performed with the use of database systems.
