| Abstrakt: | The XML format is widely used nowadays what leads to incremental usage of XML databases too. Since they are relatively new in the database management systems group, they are still intensively developed and improved. The XML database deployed at the blog.matfyz.sk portal was never optimized to gain its maximal performance. This led to database crashes and long execution time of statements. The main goal of this work was to optimize the XML database deployed at our portal. In this work we introduced the background of the XML databases and described them in detail. Next part of the work was to analyse the existing database optimization and to propose optimization techniques, which could be used during the benchmarking. We created two benchmarks, which measured the improvement of the statement and action (e.g., homepage loading) execution time using proposed optimization techniques. The benchmark results showed that these optimization techniques boosted the database performance significantly.
