Performance of the relational and non-relational databases / Prestanda för de relationella och icke-relationella databaserna

Alkhalaf, Ahmed, Al-Zubeidi, Hasan January 2023 (has links)
There are many types of databases, but the most common are relational and non-relational. These databases have different structures, and that affects their performance. Many studies examine the differences between relational and non-relational databases and compare them regarding performance. However, it lacks a study that collects the results from different sources and makes them available to software professionals, so they can choose a suitable database effortlessly. This thesis examines and analyzes several studies investigating the performance of relational and non-relational databases. The analysis examines the performance of typical database operations, insert, delete, update, and select, on different numbers of records. The results of this study show that the non-relational databases perform better, regardless of the number of records in the database. However, there are some cases where the relational databases perform better. The findings are based on an analysis of seven studies, encompassing databases MSSQL, MySQL, PostgreSQL, Oracle, and MongoDB. / Det finns flera typer av databaser, men de vanligaste är relationella och icke-relationella. Dessa databaser har olika strukturer, vilket påverkar deras prestanda. Många studier undersöker skillnaderna mellan relationella och icke-relationella databaser och jämför deras prestanda. Dock saknas en studie som samlar resultaten från olika källor och gör dem tillgängliga för mjukvaruproffs, för att underlätta valet av en lämplig databas. Denna examensarbete undersöker och analyserar flera studier som utforskar prestandan hos relationella och icke-relationella databaser. Analysen fokuserar på prestandan för vanliga databasoperationer, såsom infogning, borttagning, uppdatering och val, för olika antal poster. Resultaten av denna studie visar att icke-relationella databaser presterar bättre oavsett antalet poster i databasen. Det finns dock vissa fall där relationella databaser fungerar bättre. Resultaten baseras på en analys av sju studier som omfattar MSSQL, MySQL, PostgreSQL, Oracle och MongoDB-databaserna.
