The Support of XML Technologies in Oracle DB, IBM DB2 and Microsoft SQL Server

The aim of this thesis is to perform an all-round comparison analysis of XML technologies support in three database systems: Oracle DB, IBM DB2 and SQL Server. It includes a theoretical technologies description and their comparison analysis, along with implemented software which is designed to run experiments by querying XML data using XQuery, SQL/XML technologies and XMark benchmark. It provides the comparison of database performances based on different storage methods, create time comparison statistics, export results to a text file and store the history of previous results. The main part of the work is the demonstration of several experiments run and a detailed analysis of the database performances based on the obtained results
