A comparative analysis of the performance of the relational database and the Hadoop environment in the context of analytical data processing

The article presents a detailed comparative analysis of the performance of a Microsoft SQL Server relational database and an Apache Hadoop environment in the context of analytical data processing. The study was carried out by execut-ing more than a dozen research scenarios with different queries on datasets of varying sizes. For each research scenario, the average query execution time on different datasets was compared. Based on the results, it was found that the average execution time of queries from the presented scenarios is significantly shorter in MS SQL Server than in Apache Ha-doop
