Efficiency has been a pivotal aspect of the software industry since its
inception, as a system that serves the end-user fast, and the service provider
cost-efficiently benefits all parties. A database management system (DBMS) is
an integral part of effectively all software systems, and therefore it is
logical that different studies have compared the performance of different DBMSs
in hopes of finding the most efficient one. This study systematically
synthesizes the results and approaches of studies that compare DBMS performance
and provides recommendations for industry and research. The results show that
performance is usually tested in a way that does not reflect real-world use
cases, and that tests are typically reported in insufficient detail for
replication or for drawing conclusions from the stated results.Comment: 36 page
